Pasted Open Mouth Paper Bags — Applications, Color‑Coding Design, and Standards‑Driven Specification

What is Pasted Open Mouth Paper Bags?

Pasted Open Mouth Paper Bags are multi‑wall kraft sacks built with a pasted bottom (factory‑glued base panels that form a flat, square footing) and an open mouth at the top for filling. After dosing, the open mouth is closed by sewing (with or without crepe tape), by sewing plus PE tape for better dust control, or—if the top ply carries a heat‑sealable layer—by pinch‑sealing on a hot bar. In the trade you will also see aliases such as Sewn‑Open‑Mouth pasted bags, SOS pasted open‑mouth sacks, square‑bottom open‑mouth bags, multi‑wall paper sacks (pasted bottom), and for heat‑seal variants PBOM (pinch‑bottom open mouth) paper bags. Although the labels vary, the purpose is consistent: deliver tidy, stack‑stable packaging for dry, free‑flowing goods.

Key features of Pasted Open Mouth Paper Bags include a carton‑like base that resists bulging, breathable walls that allow trapped air to escape, high‑contrast printable faces for branding and regulatory information, and flexible closure choices that match manual or automated lines. Options extend from PE tubular liners (≈ 20–80 µm) for moisture‑sensitive products to aqueous barrier coatings when repulpability is prioritized. Typical capacities range from 5 kg to 50 kg, with 25 kg the most common industrial SKU.

How are Pasted Open Mouth Paper Bags produced? Converters draw reels of kraft paper (often 70–100 g/m² per ply), build 2–6‑ply tubes, paste a square bottom with water‑based or hot‑melt adhesives, cut to length, insert optional liners, and prepare the open mouth for the chosen closure. Printing is typically water‑based flexography up to 6–8 colors. Each lot undergoes visual, dimensional, and strength checks before bundling and palletizing.

Where are Pasted Open Mouth Paper Bags used? They excel in flour, sugar, and milled grains, animal feed and premixes, retail‑facing charcoal and biomass pellets, gypsum, lime, and dry mortars, mineral powders and additives, seeds and agricultural inputs, and specialty chemicals that are free‑flowing and can tolerate or benefit from breathable walls.

Why Pasted Open Mouth Paper Bags? A closure that reshapes the packing line

A valve bag hides complexity in a corner sleeve; a form‑fill‑seal film asks the machine to fabricate the bag live. Pasted Open Mouth Paper Bags choose a third path—a ready‑made, square‑bottom sack with a wide, open inlet. That single design decision changes the shop‑floor calculus: simpler dosing funnels, fewer change parts, easier visual inspection of fill level, and mouth closures that maintenance teams already know.

Start with the physics. Free‑flowing particles bring air with them. Paper’s porosity lets that air migrate out of the stack, so the pallet settles faster, tilts less, and needs less wrap. Consider the optics. A paper face accepts water‑based inks beautifully—deep blacks for barcodes, natural fibers for a premium finish. And do not ignore ergonomics. Operators can see the fill cone, clear a bridge, or add a sample scoop without fighting a valve sleeve.

Where does this closure shine? When dust is moderate, when breathability helps (flour, semolina, sugar), when warehouse teams value big, legible labels and color stripes for fast identification, and when the brand wants square shoulders on the retail face.

Systems view: breaking the bag into subsystems—and then stitching it back together

Good packaging is a system, not an isolated bill of materials. We decompose Pasted Open Mouth Paper Bags into seven subsystems and treat each as a small engineering problem before re‑integrating the whole.

1. Paper & plies — virgin vs recycled kraft; natural vs bleached; ply grammage (typ. 70–100 g/m²); fiber orientation; Cobb sizing level; expected bursting and tearing metrics.
2. Pasted bottom geometry — fold architecture, adhesive type (starch/dextrin vs hot‑melt), nip pressure/time, squareness tolerance; how the base carries column loads.
3. Top closure — sewn only; sewn + crepe tape; sewn + PE tape; pinch‑seal (PBOM style). Each path scores differently on dust, moisture, speed, and openability.
4. Liner or barrier — tubular PE (20–80 µm) for moisture control, or water‑based barrier coatings to prioritize mill repulpability; liner tacking strategy.
5. Print, labels, and identification — water‑based flexo, barcode contrast, ΔE* color control, color‑coding stripes for SKU families, label adhesives, anti‑scuff varnishes.
6. Handling & unitization — anti‑slip targets, pallet patterning, corner protection, strap/wrap plan; tilt‑table and vibration performance.
7. Compliance & recovery — food‑contact declarations (paper and liners), quality system certificates, forestry chain‑of‑custody, and material recycling documentation.

The reintegration step ensures a gain in one area (e.g., stronger seam) does not cost us performance elsewhere (e.g., mouth scuffing or harder opening).

Where Pasted Open Mouth Paper Bags fit best: use‑case mapping with reasoning

Food ingredients with hygiene routines

Flour, starch, powdered sugar, cereal blends: these products inhale humidity and exhale air. Pasted Open Mouth Paper Bags with breathable outers let pallets “settle,” minimizing ballooning. A sewn‑top plus crepe tape bridges needle holes, restrains fines, and keeps the mouth serviceable on a standard closer. Where shelf life needs a boost, a 30–60 µm PE liner maintains the paper look while lowering WVTR.

Animal feed and premixes

SKU sprawl is common and picking errors are costly. Pasted Open Mouth Paper Bags present wide panels for human‑readable SKU blocks and GS1‑128/QR codes. Add standardized side‑gusset stripes—blue for poultry, green for ruminants, red for swine, yellow for aquaculture—and warehouse teams can sort at ten paces.

Dry mortars and building materials

Gypsum, lime, light mortars, tile adhesive: moderate dust, high abuse. The pasted square bottom keeps columns true, and a sewn + PE tape mouth reduces wicking in damp seasons. Anti‑slip varnish raises static COF so stacks don’t slide, while the paper face tolerates scuffs better than glossy films in rugged yards.

Retail‑facing charcoal and biomass pellets

Residual off‑gas and air must escape; glossy film balloons, paper breathes. Pasted Open Mouth Paper Bags with vent patches or micro‑perfs keep bags flat, the square base keeps displays tidy, and the matte face telegraphs a natural, outdoor aesthetic.

Specialty minerals and additives

Traceability matters here. The generous printable area on Pasted Open Mouth Paper Bags allows large batch codes, hazard pictograms, and dual barcodes (front and gusset) so scanning works even after pallets are stretch‑wrapped.

Data you can plan around: market‑realistic windows

What do suppliers actually offer, and what do plants actually run? Public B2B listings and converter specs align around these windows for Pasted Open Mouth Paper Bags. Treat them as starting points and confirm by trial.

• Ply count: 2–6 plies
• Ply grammage: outer 70–100 g/m²; inner 70–90 g/m²; bleached outer optional for premium print
• Bag sizes: width 300–800 mm; length 500–1100 mm; bottom width 90–160 mm
• Capacity: 5–50 kg (25 kg most common)
• PE liner: 20–80 µm tubular insert; bottom‑tacked, top free or lightly tacked
• Printing: 1–8 colors water‑based flexo; spot varnish; matte/gloss
• Cobb (ISO 535): sized outer 30–50 g/m² (60 s); uncoated kraft 80–120 g/m²
• Targets for strength: tensile (ISO 1924‑2), tear (ISO 1974/TAPPI T414), burst (TAPPI T810) tuned to route risk

These figures are not promises; they are engineering ranges that shorten the path to a spec that behaves.

Engineering Pasted Open Mouth Paper Bags from the inside out

Paper selection with numbers, not adjectives

Choosing “stiff” or “nice‑feeling” paper is not a spec. We anchor Pasted Open Mouth Paper Bags to quantifiable metrology: basis weight (TAPPI T410), caliper (T411), tensile (ISO 1924‑2), tearing (ISO 1974 / TAPPI T414), burst (TAPPI T810), Cobb (ISO 535), and humidity conditioning (TAPPI T402). A flour route might value lower Cobb and higher burst; a dry mortar route might accept higher Cobb in exchange for tougher outer ply.

Bottom pasting—the geometry that decides stack destiny

Leaning pallets often trace back to the base. We pre‑crease panels; apply starch/dextrin or hot‑melt in controlled ribbons; close the base under calibrated nip pressure; and check squareness with go/no‑go gauges. Peel/shear checks (drawing from ASTM F904/F88 logic) reveal weak bonds before they ship. When the geometry is true, the pallet builds like masonry.

Top‑closure options and trade‑offs

• Sewn only — cost‑efficient, forgiving, easy to open; needle holes allow some dust and wicking.
• Sewn + crepe tape — bridges holes, neat appearance, tension‑relief on thick fills.
• Sewn + PE tape — adds moisture defense along the seam; useful in coastal climates and for hygroscopic products.
• Pinch‑seal (PBOM‑style) — hermetic when specified; premium look; requires heat‑seal control and typically a different closer.

There is no “best,” only best‑for‑this‑SKU‑and‑this‑route.

Liner strategy—moisture without mess

Hygroscopic powders cake; liners help. A 30–60 µm PE insert, bottom‑tacked, keeps the top free to shape with the fill cone. Where mills demand easier repulping, water‑based dispersion coatings offer modest barriers without a separate plastic layer. Either way, claims should match recycling reality, not wishful thinking.

Printing, labels, and the warehouse language

Mis‑picks are a silent tax. Pasted Open Mouth Paper Bags can carry a visual management system baked into the artwork:

• Color stripes—continuous bands (e.g., 15–30 mm) on the gusset or panel: blue, red, green, yellow, orange. Stripes communicate category before text is legible.
• Human‑readable SKU blocks—large fonts (90–120 pt on 25 kg bags) visible at 5–10 m.
• GS1‑128 or QR codes—placed in scuff‑safe zones; print quality verified to ISO/IEC 15416 grade C or better.
• License‑plate pallet labels—link pallet ID to batch, lot, and certificate of analysis; barcodes repeat on two elevations for scan convenience.
• Contrast‑aware palette—icons + stripe + text, so even dust‑grayed bags remain unambiguous.

When labels must endure rain or condensation, synthetic or varnished paper labels with peel ≥ 6–10 N/25 mm (method adapted from ASTM D3330) keep data attached.

Quality gates and third‑party verifications

Pasted Open Mouth Paper Bags translate craft into criteria. Typical lot‑release plans cite the standard numbers to keep audits objective.

• Paper metrology — T410 basis weight; T411 caliper; ISO 1924‑2 tensile; ISO 1974/T414 tearing; T810 burst; ISO 535 Cobb; T402 humidity conditioning before tests.
• Bag performance — drop/stack/vibration verified with procedures mapped to ISO 21898 (sacks—performance requirements and tests) and adjusted for paper specifics.
• Printing & optics — color ΔE* (ASTM E1164), whiteness/yellowness (ASTM E313), Sutherland rub (ASTM D5264); barcode grading (ISO/IEC 15416); label peel (ASTM D3330‑style).
• Food‑contact — for food‑adjacent SKUs: FDA 21 CFR 176.170 / BfR XXXVI for paper; if liners are present, 21 CFR 177.1520 and EN 1186 overall migration; inks aligned with EuPIA and Swiss Ordinance policies where required.
• Systems & sourcing — ISO 9001:2015 for QMS; FSC® chain‑of‑custody on request; ISO 22000 or BRCGS Packaging for hygiene management where applicable; ISO 18604 for packaging and the environment—material recycling.

Third‑party labs (SGS, Intertek, TÜV, BV) can witness or replicate key tests. Certificates of analysis list acceptance windows and retain samples, so claims rest on numbers, not anecdotes.

Case narratives—problem → solution → result

Case 1: Flour mill, 25 kg route, humid monsoon season

Problem — caking and barcode smear on arrival.
Solution — outer ply treated to Cobb 35–45 g/m² (60 s); switched from sewn‑only to sewn + crepe tape; added 40 µm PE liner; moved barcodes into recessed, low‑scuff panels; rub target set with ASTM D5264.
Result — caking claims dropped; barcode grade improved to ≥ C at receiving; pallets gained one extra layer without lean.

Case 2: Animal premix producer with 100+ SKUs

Problem — 1–2% picking errors from look‑alike bags.
Solution — color‑stripe program (25 mm bands on gusset: blue/poultry, green/ruminant, red/swine, yellow/aqua); 90‑pt SKU blocks; GS1‑128 license‑plate labels; dual barcode placement (face + gusset).
Result — picking errors fell to < 0.2%; cycle counts finished faster; forklift operators reported quicker line‑of‑sight recognition at 8–10 m.

Case 3: Dry mortar brand seeking squarer retail stacks

Problem — sagging faces and corner damage.
Solution — pasted‑bottom geometry retuned; anti‑slip varnish raised static COF; outer ply stiffened from 70 → 90 g/m²; switched to sewn + PE tape at the mouth for damp months.
Result — stacks kept their edge; wrap layers reduced; complaint rate fell through the next two quarters.

Comparative lens—POM vs PBOM vs pasted valve bag

• Pasted Open Mouth (POM) — breathability, simplicity, broad closure choices; best for free‑flowing fills with moderate dust; outstanding print area and warehouse readability; cost‑efficient conversion.
• Pinch‑Bottom Open Mouth (PBOM) — heat‑sealed top for near‑hermetic closure; premium look; tighter process control; excellent for fine or sensitive powders where dust/moisture control is paramount.
• Pasted Valve Bag — fastest fills on impeller/air packers; excellent dust containment; mouth is inaccessible after filling; chosen for cement‑like products and very fine powders at high bpm.

The question is not which is universally “better,” but which format minimizes trade‑offs for your product physics, line assets, and route risks.

Environmental and recovery notes without greenwash

Paper‑only Pasted Open Mouth Paper Bags are broadly repulpable at mills that accept multi‑wall sacks; choose water‑dispersible adhesives to avoid stickies. Paper + PE‑liner designs can still be circular if the liner separates cleanly; when mill repulping dominates, aqueous barrier coatings are often the better route. Recyclability statements should be qualified by geography and access to programs, consistent with the FTC Green Guides and regional guidance.

Warehouse‑friendly design—the little details that matter day‑to‑day

• Dual orientation — duplicate the SKU block and barcode on the gusset so codes remain scannable on stacked pallets.
• Moisture‑resistant labels — synthetic or varnished labels keep data legible in damp climates; specify peel strength windows (≥ 6–10 N/25 mm) at service temperature.
• Iconography — standardized handling icons; invert on color stripes for high contrast.
• Ergonomics — hand‑hold notches for sub‑25 kg retail SKUs, placed clear of the sew line.
• Anti‑counterfeit — serialized QR tied to a validation database; microtext in a stripe; UV‑responsive spot for field checks.
• Traceability — pallet labels that carry lot ID → materials → process conditions → test results, so disputes close with data.

A practical blueprint for specification and launch

1. Define the payload & route — net weight (5/10/20/25/50 kg), bulk density, dust class, humidity/temperature exposure, export distance, target stack height.
2. Choose paper & plies — for example, 3‑ply 80/80/70 g/m² with sized outer; set Cobb, tensile, tear, and burst windows.
3. Select the closure — sewn; sewn + crepe; sewn + PE tape; or pinch‑seal (PBOM) where hermeticity is required.
4. Choose liner/coating — none; PE insert 30–60 µm; or dispersion barrier for repulpability.
5. Engineer identification — color stripes (15–30 mm), big SKU blocks, GS1 barcodes (ISO/IEC 15416 grade ≥ C), duplicate codes on gusset.
6. Plan handling — static COF target for column strength, wrap tension tuned for paper, corner protection, pallet pattern.
7. Write tests & documents — standards above; lot‑level COA; certificates for ISO 9001, FSC®, and—where needed—food‑contact and hygiene standards.
8. Pilot, then freeze — run drop/tilt/vibration and coastal storage simulations; lock acceptance windows; define sampling and retains; publish a user‑friendly spec sheet for procurement and QA.

Follow this path and Pasted Open Mouth Paper Bags stop being a commodity description on a purchase order and become a tuned, auditable component of your operation—easy to recognize on a shelf, easy to trust on a pallet, and easy to defend in an audit.

Introduction — What, Features, Process, and Uses of Pasted Open Mouth Paper Bags

Pasted Open Mouth Paper Bags are multi‑wall kraft sacks with a factory‑glued square bottom and an open top designed for fast filling on auger, gravity, or belt feeders. In day‑to‑day sourcing they may also be called Sewn‑Open‑Mouth pasted bags, square‑bottom open‑mouth sacks, multi‑wall paper sacks (pasted bottom), or—when the mouth carries a heat‑sealable layer—PBOM (pinch‑bottom open mouth) variants. The appeal is straightforward: carton‑like stackability, breathable yet printable walls, and simple, serviceable closures. Typical construction spans 2–6 plies of 70–100 g/m² kraft, with the option of a 20–80 µm PE tubular liner for moisture‑sensitive contents.

What distinguishes Pasted Open Mouth Paper Bags in practice? High edge stiffness for square pallets; large printable faces for branding and regulatory marks; closure flexibility (sewn only, sewn plus crepe tape, sewn plus PE tape, or pinch‑sealed when specified); and strong compatibility with warehouse identification systems. Production follows a clean chain—ply selection and tuber formation, bottom pasting with water‑based or hot‑melt adhesives, cut‑to‑length, optional liner insertion, print/inspection, and palletization. Where do they shine? In flour, sugar, and milled grains, animal feed and premixes, charcoal and biomass pellets, gypsum, lime, and dry mortars, and specialty minerals that benefit from breathable walls and tidy stacks. For a quick overview and adjacent formats, see: Pasted Open Mouth Paper Bags.

Problem‑Led Framing — Why choose Pasted Open Mouth Paper Bags over other formats?

The immediate problem in many plants is not capacity but consistency: bags that lean, barcodes that smear, seams that shed dust. Pasted Open Mouth Paper Bags tackle these pains by design. The pasted base spreads load like a mini‑carton, reducing column creep. Breathable paper allows entrapped air to escape after filling, so pallets settle without ballooning. The open mouth simplifies dosing hardware and visual QC—operators can see the fill cone, correct a bridge, or sample without contending with a valve sleeve. The result is less downtime and fewer cosmetic downgrades. Is the trade‑off worth it? When dust is moderate and breathability helps, the answer is usually yes; where ultra‑fine powders demand near‑hermetic containment, a PBOM or pasted valve bag may be better.

Method — From sub‑problems to an integrated specification

System thinking converts a vague “buy paper bags” brief into a measurable plan. We split Pasted Open Mouth Paper Bags into five sub‑problems and solve them in sequence before we recombine: (1) paper/ply recipe; (2) bottom geometry; (3) mouth closure; (4) liner or barrier approach; (5) identification and unitization. Horizontally, we borrow methods from corrugated engineering (column strength), from labeling science (barcode contrast, ISO/IEC 15416), and from flexible packaging (rub resistance, ASTM D5264). Vertically, we track cause‑and‑effect: heavier outer plies increase stiffness, which improves stack height but may require lower wrap tension to avoid scuff; tighter Cobb lowers water uptake, which protects print but can reduce breathability—so liner decisions and Cobb targets must be set together, not apart.

Result — What outcomes should a well‑specified program deliver?

A successful rollout of Pasted Open Mouth Paper Bags tends to move the same needles: squarer stacks (fewer topple interventions), cleaner mouths (less product loss and less housekeeping), stable barcode grading at intake (C or better), and fewer warehouse picking errors thanks to deliberate visual design. On the cost side, total wrap per pallet typically falls when static friction is raised via anti‑slip varnish; rework hours drop when sewn seams are taped; and claim rates from scuff or lean trend down quarter‑over‑quarter. None of these are miracles; all of them are the predictable result of tuning the small pieces and measuring what matters.

Discussion — Materials and structure of Pasted Open Mouth Paper Bags

At the core sits paper choice. Virgin or recycled kraft? Natural or bleached? Common practice uses 3–4 plies around 70–100 g/m² each, specified by basis weight (TAPPI T410), caliper (T411), tensile (ISO 1924‑2), tearing (ISO 1974/TAPPI T414), burst (TAPPI T810), and Cobb (ISO 535). The bottom is where geometry meets glue: pre‑creased panels, water‑based starch/dextrin or hot‑melt in controlled ribbons, calibrated nip, and square‑ness checks. The mouth closes along a spectrum—sewn only for cost efficiency; sewn plus crepe tape to bridge needle holes and neaten the edge; sewn plus PE tape to block wicking in coastal routes; and pinch‑sealed tops where near‑hermetic closure and premium appearance are demanded.

Liners earn their keep when hygroscopicity rises. A 30–60 µm PE insert bottom‑tacked inside Pasted Open Mouth Paper Bags sharply lowers WVTR while preserving a paper look; water‑based dispersion coatings offer lighter barriers while maximizing repulpability. Printing stays water‑based flexo, typically 1–8 colors, with rub limits set by ASTM D5264 and color ΔE* against a master by ASTM E1164. The aim is simple: beautiful on day one, readable after the voyage, scannable on the dock.

Identification & Color‑Coding — Turning bags into a warehouse language

Mis‑picks cost money and reputation. The large faces of Pasted Open Mouth Paper Bags are a gift: convert them into a visual system. Run standardized color stripes (blue, red, green, yellow, orange) as 15–30 mm bands along the side gusset; add human‑readable SKU blocks in 90–120 pt type for 25 kg formats; place GS1‑128 or QR codes in scuff‑safe zones; verify print quality to ISO/IEC 15416 grade C or better; duplicate codes on the gusset so stacked bags remain scannable. Stripes signal the family, icons reinforce the meaning, barcodes close the loop with the WMS. The effect is immediate: fewer errors at ten paces, faster cycle counts, calmer docks.

Horizontal vs Vertical Thinking — What changes when one knob turns?

Horizontal: borrow from other domains. From corrugated, import tilt‑table logic and column‑strength goals to judge pallet behavior. From flexible films, import COF targets to balance conveyor glide against pallet grip. From print production, import ΔE* color control so every red stripe is the same red, batch after batch. Vertical: follow chains of cause. Increase outer‑ply grammage → higher stiffness → less bulge → lower wrap layers, but also more abrasive mouth edges → add crepe tape or lower wrap tension. Tighten Cobb with varnish → better water resistance → improved barcode survival, yet lower breathability → counter with micro‑vents or slightly looser fill to allow air egress. This is how Pasted Open Mouth Paper Bags move from guesswork to governance.

Sustainability & Safety — Honest claims, testable paths

Paper‑only Pasted Open Mouth Paper Bags are widely repulpable where mills accept multi‑wall sacks; choose water‑dispersible adhesives to avoid stickies. Paper + PE liner designs should allow easy separation at end‑of‑life or rely on dispersion coatings where repulpability is paramount. Food‑adjacent SKUs lean on BfR XXXVI and FDA 21 CFR 176.170 for paper contact; if liners are used, assess overall/specific migration per EN 1186 and confirm resin status under 21 CFR 177.1520. Document material recycling per ISO 18604 and respect regional packaging rules (e.g., 94/62/EC heavy‑metal limits). The point is not to say “green,” but to show “compliant and credible.”

Buying Guide — Converting questions into numbers

Before ordering Pasted Open Mouth Paper Bags, translate reality into specification lines. Payload and density determine volume, which becomes width, length, and bottom width; desired stack height, route humidity, and dust class steer the closure (sewn only, sewn + tape, or pinch‑seal). Hygroscopic risk justifies a 30–60 µm liner or a dispersion coating; anti‑slip targets set static COF high enough for columns and kinetic COF low enough for conveyors; barcode policy fixes contrast and quiet‑zones; and QA plans cite the standard numbers—T410/T411, ISO 1924‑2, ISO 1974/T414, T810, ISO 535, ISO 21898 for sack performance, ASTM D5264 for rub, ASTM E1164/E313 for color/whiteness. When every knob has a number, procurement gets clarity and operations get consistency.

Evidence — Compact case narratives (Problem → Method → Result → Discussion)

A flour mill faced caking and smeared codes each monsoon. By specifying a sized outer ply (Cobb 35–45 g/m²), switching to sewn + crepe tape, and adding a 40 µm liner, Pasted Open Mouth Paper Bags arrived with barcode grades at C or better; pallets gained an extra layer; rework dropped. Discussion: moisture mitigation and mouth hygiene matter more than raw ply count.

A premix producer battled 1–2% picking errors. Implementing 25 mm gusset color stripes and front‑panel SKU blocks, duplicating GS1‑128 on the gusset, and setting rub targets stabilized identification. Result: <0.2% mis‑picks and quicker cycle counts. Discussion: visibility beats memory—design the bag to do the shouting.

A dry‑mortar brand complained of leaning stacks. Retuning pasted‑bottom geometry, stiffening the outer ply to 90 g/m², and applying anti‑slip varnish lifted column strength; wrap layers fell; complaint rates declined over two quarters. Discussion: the base geometry is destiny—square bottoms stack square.
