Start with the Real Bottle and Gift Job
A canvas wine carrier looks like a simple sewn item until it is loaded with glass, passed across a busy bakery counter, packed into a holiday carton, or shipped to a retailer with strict receiving rules. For an artisan bakery, the same carrier might hold a 750 ml wine bottle, a champagne bottle, a local olive oil bottle, a sauce bottle, a tasting card, crackers, tissue, ribbon, or a dessert pairing insert. Each choice changes the required height, gusset depth, handle strength, divider behavior, logo position, and packing method.
Begin the RFQ with the job the carrier must perform. Is it a checkout gift bag for walk-in customers? A reusable carrier for wine-and-bread pairings? A corporate holiday item packed by a third-party fulfillment team? A specialty retail bundle that must stand neatly on shelf? Those are different buying situations. If the supplier only sees “custom canvas wine bag with logo,” one factory may price a lightweight sleeve while another prices a reinforced gusseted carrier. The cheaper quote may simply be quoting a different product.
Bottle geometry deserves early attention. Bordeaux-style bottles are usually straighter. Burgundy bottles often have wider shoulders. Champagne bottles are commonly wider and heavier. Olive oil and sauce bottles may be tall, square, or capped in ways that add height. Give suppliers the measured bottle height including cork, cap, foil, or closure; the largest diameter; shoulder shape; and filled weight. For a two-bottle carrier, state whether both sides hold glass or whether one side may hold food. A sample can look good empty and still fail during real bakery assembly.
- Define the carrier job as promotional, reusable retail, premium gift, distributor stock, event handout, or online fulfillment packaging.
- List every item that may be packed inside, including wine, champagne, olive oil, sauces, crackers, cards, tissue, ribbon, and neck tags.
- Give bottle diameter, height including closure, shoulder profile, and maximum filled weight rather than only saying one bottle or two bottles.
- Tell suppliers whether the filled carrier must stand upright on a bakery counter, fit a secondary carton, or only be carried by hand.
- Share channel constraints such as retail shelving, warehouse bins, courier boxes, distributor labeling, or store-by-store allocation needs.
Write Specifications Suppliers Can Price and Inspect
A strong canvas wine carriers RFQ template should read less like a product idea and more like a factory instruction sheet. Keep it concise, but make it measurable. The core specification should define finished dimensions after sewing, not cut-panel dimensions. Canvas thickness, seam allowance, folded gussets, divider attachment, and handle stitching all reduce or shape the usable internal space. Procurement teams need a written basis for comparison, sample approval, and dispute resolution.
Include item name, target use, carrier type, finished size, fabric weight, fabric color, handle construction, stitching type, divider construction, print method, artwork size, label details, MOQ tiers, packing method, carton limits, sample stages, and QC standard. Use plain construction language: open top, flat bottom, boxed gusset, side gusset, bottom gusset, self-fabric handle, webbing handle, sewn divider, bartack, box stitch, and edge finishing. If the supplier recommends a change, ask them to state the change and show its effect on price, lead time, durability, or inspection.
A simple drawing prevents many expensive misunderstandings. Add front, side, and top views with arrows for height, front panel width, side gusset, bottom gusset, handle drop, handle width, divider width, divider height, and logo placement. For two-bottle carriers, show where the divider is attached. Is it caught in the side seams? Sewn into the base? Attached only near the top? Phrases such as “adjusted for production” are too vague unless the revised measurement or construction is written into the approved file.
- Use finished measurements after sewing for all dimensions and make suppliers confirm them in the quotation.
- Include front, side, and top sketches with measurement arrows for gusset, divider, handle, and logo placement.
- Define construction terms clearly so suppliers do not substitute a sleeve, tote-style bag, or unreinforced gift pouch.
- Ask suppliers to list all deviations instead of silently changing fabric weight, handle width, stitch method, divider height, or packing.
- Keep one unchanged specification sheet for every supplier so quote differences reflect real production economics, not missing requirements.
Choose Canvas Weight with Cost and Use in Mind
Canvas weight is visible to the customer and important to the sewing line. It should not be chosen by habit alone. For wine carriers, a broad practical range is about 8 oz to 16 oz cotton canvas, roughly 270 to 540 GSM depending on weave and supplier conversion. Many bakery gift programs land in the 10 oz to 12 oz range, approximately 340 to 407 GSM, because it offers a reusable feel, a clean print surface, and carton volume that is still manageable.
Lighter canvas has a place. An 8 oz or 9 oz fabric can work for short-term event giveaways, light single-bottle sleeves, or cost-sensitive promotions where compact packing matters more than standing structure. It becomes risky when the carrier needs to hold two bottles, stand on a counter, or feel premium in a holiday bundle. Heavier canvas can look more substantial, but it brings trade-offs: higher fabric cost, thicker seam intersections, slower sewing, more carton cube, and possible rejection if the factory is not set up for heavy folded construction.
Ask for both oz/yd² and GSM. Suppliers use different shorthand, and weight descriptions are not always converted consistently. Require a physical swatch from the intended fabric source, not only a photo. Check shade, hand feel, stiffness, density, odor, and print surface. For natural canvas, decide what character is acceptable. Cotton flecks, slubs, and seed marks may fit a bakery aesthetic. Stains, oil marks, mildew, strong odor, or heavy shade mismatch do not.
- Use 8 oz to 10 oz for event giveaways or low-cost single-bottle sleeves where standing structure is not critical.
- Use 10 oz to 12 oz for most bakery gift carriers that need reusable feel, good print performance, and manageable carton volume.
- Use 14 oz and above only when premium stiffness is required and the factory can sew thick handle and gusset intersections cleanly.
- Ask for both oz/yd² and GSM, then approve a physical swatch before authorizing construction samples.
- Define natural canvas character separately from defects: flecks and slubs may be acceptable, but mildew, oil marks, and strong odor are not.
Lock Fit Before Approving Artwork
Artwork approval should wait until structure is settled. A logo can look centered on a flat digital proof and then shift visually once the bottle pushes the front panel outward and the gusset opens. For a single standard 750 ml wine bottle, buyers may evaluate finished dimensions around 120-130 mm front width, 350-380 mm height, and 90-100 mm gusset as a starting point. Those numbers are not universal. Champagne, Burgundy, olive oil, and specialty sauce bottles often need different proportions.
The gusset controls stability, usable space, and packing speed. A narrow gusset saves fabric but may create a tight fit, cause leaning, or push stress into the side seams. A boxed or flat gusseted base helps the carrier stand on a counter and gives the finished gift more structure. The bottom seam also needs attention because the bottle base pushes downward while the handles pull upward. During sampling, request photos of the carrier filled with the intended bottles, not just flat sample shots.
Dividers need their own specification. A loose divider lets bottles knock together, scuff labels, and make the carrier feel poorly engineered. A tight divider slows assembly and may tilt bottles outward. State divider width, height, attachment points, and whether it is secured into the base. If one compartment may hold crackers, chocolate, jam, or a folded bakery insert instead of a bottle, provide the widest insert size. Handle drop matters too. It should be comfortable for hand carry without making the compact carrier look untidy on display.
- Confirm finished height, front width, side gusset, bottom gusset, and internal fit using real bottles before approving artwork.
- Set handle drop for comfortable hand carry while keeping the filled carrier balanced and suitable for counter display.
- Keep print placement away from gusset folds, bottom seams, and handle stitching to avoid distortion and abrasion.
- For two-bottle carriers, specify divider height and base attachment if bottle separation is a critical requirement.
- Require suppliers to photograph samples filled with actual bottle types, including front, side, top, and divider views.
Match Branding to Canvas and Handling
Branding is often the reason a bakery invests in custom canvas wine carriers, but decoration must match the material and the way the bag will be handled. Screen printing is usually the first option to test for one- to three-color bakery logos, seasonal graphics, and event marks. It can deliver practical unit economics at moderate volumes and a familiar matte look on cotton canvas. Still, ink must be tested on the selected canvas shade because texture, natural flecks, and absorbency can soften edges or shift perceived color.
Heat transfer and digital print can help when artwork has gradients, many colors, or fine details. They also bring different risks: cracking over folds, poor adhesion on textured canvas, glossy patches, edge lifting, or a finish that feels less natural than the bakery intended. Embroidery can feel premium for a small mark, but it can pucker lighter canvas and is rarely ideal for large filled logos. Woven labels, cotton labels, or small patch details work well when the buyer wants subtle branding that can carry across wine bags, totes, and gift packaging.
Treat branding as data, not decoration language. Provide artwork files, print size, number of colors, Pantone or brand references, print position from bottom and side seams, maximum placement tolerance, and whether one or both panels are printed. Ask the supplier to state screen charges, minimum line thickness limits, and expected color variance on natural or dyed canvas. If brand color is strict, review the pre-production sample under daylight and store lighting; warm bakery lighting can change how ink reads on natural cotton.
- Use screen print for solid logos, simple holiday artwork, and 500-plus piece orders where unit economics matter.
- Use heat transfer or digital print only after adhesion, flexibility, rubbing, odor, and visual finish are approved on the selected canvas.
- Use embroidery for small premium marks rather than large dense artwork on lightweight panels.
- Use woven labels or side labels when the brand wants understated identification across wine bags, totes, and gift packaging.
- Measure logo placement from seams and center lines, and define tolerance in millimeters before production.
Request Quotes That Reveal the Real Cost Drivers
A low quote is only useful when it is built on the same product. Canvas wine carrier pricing is shaped by fabric consumption, canvas grade, dyeing, cutting efficiency, handle construction, seam complexity, divider labor, print setup, number of print colors, label details, packing material, carton size, and inspection requirements. If those assumptions are not visible, procurement may select a price that cannot deliver the requested carrier.
Ask suppliers to quote 500, 1,000, and 3,000 pieces against one unchanged specification. That makes volume breakpoints easier to see. A simple natural canvas single-bottle carrier with one-color screen print may show meaningful savings as setup and cutting are spread across more units. A dyed two-bottle carrier with a divider, woven label, and individual packing may have a higher practical minimum because dyeing, label production, and sewing setup create fixed costs. Do not compare a 500-piece quote for simple construction with a 3,000-piece quote for a premium build.
Line-item clarity is essential for B2B buying. Ask suppliers to separate unit price from screen charges, sample fees, courier charges, label cost, special packing, export carton, inspection support, cutting charges, and artwork conversion. Also request estimated carton dimensions and gross weight at quote stage. A lower unit price may not be lower landed cost if the carrier is heavier, packed loosely, or shipped in oversized cartons. Compare product, decoration, packing, freight volume, duty assumptions if applicable, inspection, and rework risk together.
- Quote MOQ tiers at 500, 1,000, and 3,000 pieces without changing fabric, print size, construction, or packing.
- Separate setup charges from unit price so reorders and seasonal artwork changes can be budgeted accurately.
- Compare natural, bleached, dyed, recycled, and organic canvas as separate options if sustainability or color is part of the brief.
- Request carton dimensions and gross weight early so the buyer can estimate storage, freight, and receiving impact.
- Treat quotes that omit fabric weight, handle reinforcement, print method, tolerance, or packing data as preliminary rather than final.
Ask for Supplier Evidence Before Sampling
A useful supplier response gives more than price and lead time. Wine carriers hold heavy glass, so the buyer should look for evidence that the supplier understands load concentration, seam stress, print placement, and export packing. Ask for photos of similar bottle bags, close-ups of handle attachment, bottom seam images, divider construction, sample swatch cards, print examples on canvas, packed carton photos, and a basic internal inspection checklist. Evidence from flat tote bags alone is not enough.
Clarify which processes are in-house and which are subcontracted. Subcontracting is not automatically negative, but it affects schedule control and accountability. If printing is handled outside the sewing factory, who owns the issue if color, placement, adhesion, or odor fails? If woven labels or patches are ordered from another vendor, are they on the critical path for a seasonal launch? These dependencies should be visible before the purchase order is placed.
Documentation needs vary by market, channel, and brand policy. Some buyers may need recycled content documentation, organic cotton certification, restricted substance declarations, carton labeling rules, or retailer-specific packaging standards. Ask what the supplier can support and whether the documentation applies to the actual material quoted. Even when the carrier does not touch food directly, odor, cleanliness, moisture, and storage conditions matter because the item will be handled around bakery products.
- Request similar product photos that show bottle carriers, handle reinforcement, bottom seams, and divider construction.
- Ask which processes are in-house and which are subcontracted, then identify who signs off on final quality.
- Confirm available documentation for material composition, recycled content, restricted substances, or retailer packaging needs if relevant.
- Ask suppliers to list production risks they see in the specification instead of only confirming that everything is possible.
- Require a written inspection plan or checklist before deposit so quality expectations are visible to both sides.
Use Sample Gates Instead of One Big Approval
Sampling works best as a sequence. Approve fabric first: weight, shade, hand feel, stiffness, surface texture, odor, and any sustainability claim. Then approve blank construction: finished size, gusset, divider, handle drop, seam quality, standing ability, and bottle fit. After that, approve decoration: logo size, color, opacity, edge sharpness, placement, adhesion, and rubbing behavior. Finally, approve packing: fold method, bundle count, inner packing, export carton, shipping marks, and carton fill.
This staged approach prevents a common and costly mistake: approving a beautiful printed sample before the structure is correct. A carrier may look excellent in photos but still be too narrow for champagne, too soft to stand on a counter, or weak at the handle root. For bakeries working toward holiday launch dates, a late structural change can force new cutting, revised artwork placement, and new carton planning. That creates more risk than a small delay in artwork approval.
State in the RFQ that bulk production cannot begin until written pre-production approval is issued. Keep one approved sample with the buyer and one with the factory. If photo approval is part of the process, specify required views: front, back, side, top opening, inside divider, handle close-up, bottom seam, filled bottle view, logo close-up, folded packing view, and packed carton. Physical samples are still important for hand feel, stiffness, odor, load testing, and print texture.
- Approve fabric swatch before construction sampling if shade, stiffness, or sustainability positioning matters.
- Test blank samples with actual bottles and bakery inserts before approving print placement.
- Approve printed samples under daylight and store lighting because ink can look different on natural canvas.
- Require close-up photos of handle stitching, bottom seam, divider, logo edge, fold method, and carton packing before final approval.
- Keep matched approved samples at the buyer and factory for bulk inspection comparison.
Define QC Tolerances and Defect Classes Early
Quality control belongs in the RFQ, not in a dispute after production. For canvas wine carriers, inspection should cover fit, strength, appearance, decoration, packing, and carton condition. The checklist should include finished size measurement, fabric shade comparison, GSM verification where practical, stitch density, seam security, handle load test, divider alignment, print adhesion, logo placement, thread trimming, stains, odor, and packing accuracy. Because the product carries glass, handle and bottom seam issues should be treated as safety or function risks, not minor cosmetic flaws.
Use numbers wherever possible. Finished dimensions might start around plus or minus 5 mm for height and width on a simple carrier, with final tolerance adjusted for construction complexity. Handle drop and logo placement may be controlled around plus or minus 3 mm to 5 mm. Load testing should define the weight, method, duration, and pass/fail criteria. For example, use the heaviest intended filled contents plus a buyer-defined safety margin for a specified time, then inspect for seam opening, handle tearing, fabric distortion, or permanent elongation.
Write defect classes clearly. Critical defects may include broken handle stitching, open bottom seams, unsafe hardware if used, mildew, strong odor, or wrong construction. Major defects may include size outside tolerance, visibly crooked logo, severe shade mismatch, failed print adhesion, wrong carton quantity, or divider misalignment. Minor defects may include small loose threads or natural fabric variation within the approved range. If a third-party inspection is planned, state the AQL level, sample size, and whether the inspector must perform load testing or only visual and measurement checks.
- Classify handle failure, bottom seam opening, mildew, strong odor, unsafe hardware, and wrong construction as critical defects.
- Measure dimensions, handle drop, divider position, and logo placement against the approved sample and written tolerance.
- Check print opacity, rubbing, adhesion, color match, edge sharpness, registration, odor, and transfer marks between stacked pieces.
- Define acceptable natural canvas flecks and slubs separately from stains, oil marks, dirt, mildew, and shade mismatch.
- Include packing and carton checks in final inspection because crushed cartons and wrong counts create receiving problems.
Plan Packing, Cartons, and Receiving
Packing affects presentation, freight cost, storage, and receiving accuracy, so it should not be left as an afterthought. Canvas wine carriers may be packed flat in bundles, individually polybagged, paper-banded, interleaved to protect print, placed in inner cartons, or packed directly into export cartons. Many artisan bakeries and specialty retailers prefer reduced plastic. That can work, but the buyer still needs protection against print rubbing, moisture, dirt, and warehouse picking errors.
Define fold direction and bundle method. Poor folding can leave permanent creases across the logo or deform handles before the carrier ever reaches a store. If the screen print area is large, fresh, or heavy, ask whether interleaving is recommended. If individual stores receive small quantities, inner packs or clearer carton marks may reduce allocation mistakes. For distributor delivery, carton marks should include purchase order, item code, color, quantity, gross weight, carton number, and destination routing when required.
Carton gross weight matters for both workers and product condition. Overfilled cartons can crush lower cartons, distort handles, and rub printed panels. Underfilled cartons waste freight space and may collapse during stacking. Request estimated carton dimensions and gross weight with the quotation, then require final carton data before shipment booking. A packed carton photo should show the open carton, fold orientation, bundle count, shipping mark, and closed carton condition. It is a small request that often catches practical issues before goods leave the factory.
- Specify flat pack, bundle count, paper band, master polybag, individual polybag, inner carton, or other required packing method.
- Protect printed panels with controlled stacking or interleaving when rubbing or ink transfer is a realistic risk.
- Set a maximum export carton gross weight that warehouse teams can handle safely and that prevents carton crush.
- Require carton marks to match purchase order, item code, color, quantity, carton number, gross weight, and destination instructions.
- Ask for final carton dimensions, gross weight, carton list, and packed carton photos before shipment handover.
Specification comparison for buyers
| RFQ decision | Recommended specification | Best-fit bakery use case | Procurement risk to control |
|---|---|---|---|
| Bottle profile | Quote against measured contents: bottle height, largest diameter, shoulder shape, filled weight, and closure height for 750 ml Bordeaux, Burgundy, champagne, olive oil, sauce, or mixed gift bottles. | Wine-and-bread pairings, holiday hampers, tasting kits, condiment bundles, and specialty retailer gift sets. | A bag sized for a straight Bordeaux bottle may be too short, narrow, or unstable for champagne or wide-shouldered Burgundy bottles. |
| Canvas weight | Specify cotton canvas in both oz/yd² and GSM; common practical range is 10-12 oz, approximately 340-407 GSM, with swatch approval from the intended production lot. | Reusable bakery gift carriers needing a clean print surface, credible hand feel, and manageable carton volume. | A lighter fabric can sag or show bottle edges; heavier fabric can increase seam bulk, sewing time, carton cube, and freight cost. |
| Finished dimensions | State finished dimensions after sewing: height, front width, side gusset, bottom gusset, handle width, handle drop, divider width, and logo position. | Programs requiring consistent fit across store packing teams, distributors, and online gift assembly. | Cut dimensions are not inspection dimensions; seam allowance and folded gussets can reduce internal space. |
| Construction format | Single-bottle open-top carrier for simpler gifting; two-bottle carrier with secured divider when glass bottles are paired. | Checkout gifting, winery-bakery collaborations, corporate food gifts, and seasonal retail bundles. | A loose divider can allow bottle contact; an over-tight divider slows packing and can scrape labels. |
| Handle reinforcement | Require self-fabric or webbing handles with box stitch plus bartack, dense X-stitch, or equivalent reinforced attachment at each handle root. | Repeated store handling, event distribution, courier handoff, and gift assembly with filled glass bottles. | Handle root failure is a critical defect and should be controlled by load testing, not visual approval only. |
| Base structure | Use a boxed or flat gusseted base with reinforced bottom seam; define whether the bag must stand upright when filled. | Counter display, gift presentation, staff packing, and carton stacking before distribution. | A flat sleeve saves fabric but may tip over, crease the logo, and look weak when loaded. |
| Branding method | Screen print for solid one- to three-color logos; woven label, cotton label, or small embroidery for subtle premium marks; test heat transfer or digital print before bulk. | Bakery logos, holiday artwork, tasting event marks, and private-label gift programs. | Ink opacity, edge definition, rubbing, placement, and cracking must be checked on the actual canvas color and texture. |
| MOQ tiers | Request 500, 1,000, and 3,000 pieces using one unchanged specification, packing method, and inspection standard. | Budget planning across pilot runs, holiday volume, multi-location replenishment, and reorder programs. | Changing fabric weight, logo size, divider, or carton packing between tiers makes supplier comparisons unreliable. |
| Packing method | Define flat pack orientation, bundle count, print protection, inner pack, export carton quantity, carton marks, and maximum gross weight. | Distributor receiving, bakery warehouse storage, retail backroom replenishment, and store-by-store allocation. | Overfilled cartons can deform handles and scuff prints; unclear carton marks create receiving and picking errors. |
Buyer checklist before sampling
- List every item going into the carrier: 750 ml wine, champagne, olive oil, jam bottle, sauce bottle, bakery syrup, crackers, tasting card, tissue, ribbon, neck tag, or mixed gift insert.
- Measure the tallest bottle height including cork, cap, or foil; the widest diameter; the shoulder shape; and the heaviest filled weight for each intended content set.
- Set a maximum loaded weight per carrier and require a load test target, such as the intended filled weight plus a defined safety margin, held for a defined duration.
- Specify finished dimensions after sewing: height, front panel width, side gusset, bottom gusset, divider width, divider height, handle width, and handle drop.
- State fabric weight in both oz/yd² and GSM, plus natural, bleached, dyed, recycled cotton, organic cotton, or blended canvas preference if relevant to the brand or buyer policy.
- Define acceptable natural canvas character: cotton flecks, slubs, and seed marks may be acceptable; stains, oil marks, mildew, strong odor, and heavy shade mismatch are not.
- Attach artwork files with print size, Pantone or brand color references, print method preference, placement from seams, and acceptable position tolerance in millimeters.
- Ask for MOQ and pricing at 500, 1,000, and 3,000 pieces using the same fabric, construction, artwork size, packing, and inspection requirement.
- Require suppliers to separate unit price, screen or plate charges, sampling fees, courier cost, label cost, inner packing, export carton, inspection support, and any cutting or artwork charges.
- Confirm whether cutting, printing, sewing, washing, label attachment, inspection, and final packing are done in-house or subcontracted, and ask who controls QC at each stage.
Factory quote questions to send
- What exact canvas weight are you quoting in oz/yd² and GSM, and can you provide a physical swatch from the fabric batch or source intended for production?
- Is the fabric natural, bleached, dyed, recycled, organic, or blended cotton canvas, and is it stock fabric or made to order?
- What finished size are you quoting after sewing, including height, front width, side gusset, bottom gusset, handle width, handle drop, divider width, and seam allowance assumptions?
- Which bottle dimensions did you use for fit: height, widest diameter, shoulder profile, and maximum filled weight?
- For two-bottle carriers, how is the divider constructed, where is it attached, what divider height is quoted, and what bottle diameter range is it designed to separate?
- Which handle reinforcement is included: straight stitch, box stitch, X-stitch, bartack, rivet, webbing reinforcement, or another method, and can you show close-up photos?
- What load test can the finished carrier pass, using what weight, hanging or carry method, duration, and pass/fail criteria after the test?
- Which print method is included, how many colors are quoted, what maximum print area is allowed, and what file format do you need for artwork?
- Can you test print opacity, edge sharpness, rubbing resistance, adhesion, odor, and transfer marks on the selected canvas before bulk production?
- What logo placement tolerance can you hold from the side seam, bottom seam, and center line on bulk production?
Quality-control points to confirm
- Finished dimensions should be measured after sewing and pressing, not from cut panels. Practical tolerances often start around plus or minus 5 mm for main height and width, plus or minus 3 mm to 5 mm for handle drop and logo placement, but the RFQ should set the final limits by design complexity.
- Canvas GSM should be checked against the approved swatch and supplier production record because a fabric downgrade can change stiffness, print absorption, standing ability, seam bulk, and perceived value.
- Natural canvas shade, cotton flecks, slubs, and seed marks should be defined in advance so normal fabric character is accepted while stains, oil marks, mildew, dirt, and heavy shade mismatch are rejected.
- Handle attachment points must be inspected as critical areas, with no skipped stitches, broken bartacks, loose thread nests, needle cuts, seam slippage, or distortion after load testing.
- Bottom seams, gusset corners, and divider attachment points should be checked because bottle weight concentrates stress where flat fabric turns into a three-dimensional carrier.
- Load testing should use the heaviest intended filled contents plus a defined safety margin, held for a defined time, followed by inspection for seam opening, handle elongation, fabric tearing, and permanent distortion.
- Logo position should be measured from fixed references such as bottom seam, side seam, and center line rather than approved by eye only.
- Screen print quality should be checked for opacity, pinholes, edge sharpness, color match, registration, cracking, rubbing, odor, and transfer marks between stacked pieces.
- Divider alignment should keep bottles separated without excessive tightness, tilted bottle position, or label scraping during bakery staff assembly.
- Stitch density should be consistent with the approved sample, and inspectors should flag long loose ends, thread color mismatch, uneven tension, puckered panels, skipped stitches, and untrimmed thread clusters.
