Printed & laminated woven

The graphics skin of the whole family: BOPP film gravure-printed on its inner face (里印/reverse print) so the ink is sandwiched and abrasion-proof once laminated. Sold as a roll to bag converters, or made in-house by integrated factories that own a gravure press.

Processes roto-print

Finished laminate sold as a reel rather than a bag: woven PP fabric with printed BOPP already bonded to it. Bought by converters who own only bag-making machines, by FFS (form-fill-seal) bagging lines, and by exporters avoiding finished-bag trade duties.

PP woven fabric, and sacks made from it, extrusion-coated by laying a curtain of molten PE or PP straight onto the weave — no separate film and no adhesive. It is often confused with BOPP film lamination, which bonds on a pre-printed film: coating gives a waterproof, heat-sealable surface that is printed by flexo on a slightly textured face. The coating can be on the outside, inside or both faces, in PE (softer, seals more easily) or PP (stiffer, keeps the sack mono-material), for chemicals, animal feed, fertiliser, cement and dry mortar, and rice and flour.

The workhorse of the family and the highest-volume item: a flat laminated tube, one end sewn closed at the factory, the other left open for the filler to sew after filling. Everything else in this catalogue is a variation on this bag.

Sewing is replaced by a welded bottom — no needle holes, no thread wick, no loose fibres. The retail-clean construction for small consumer packs and anything with a dust or leak complaint.

Side gussets folded into the tube so the filled bag squares up instead of pillowing. Buys pallet stability and two extra print faces without moving to a full block bottom.

A separate PE bag inserted (loose or tack-welded) inside the laminated woven sack. The lamination stops rain and abrasion from outside; the liner stops moisture migration and product-to-fabric contact from inside.

Processes tape-extrusion · circular-weaving · roto-print · BOPP-print-laminate · liner-insert · cut-sew · heat-seal

A laminated bag deliberately made leaky to air. Lamination is airtight, which is fatal for products that de-gas, off-gas moisture, or must not balloon on a filling line — so holes are laser-drilled or needle-punched after lamination.

Solves the one thing everyone hates about woven sacks: you cannot open them. A laser-scored line, a PET tear tape, or a pull-string chain stitch gives a clean straight opening without a knife.

BOPP lamination makes a beautifully slippery bag — which then slides off the pallet in transit. Anti-slip lacquer or an anti-slip masterbatch in the film restores friction without killing gloss.

A BOPP-laminated woven sack with a valve sleeve set into one top corner: the packer's spout fills the sack through the sleeve, and the sleeve is pressed shut by the product when filling stops, so filling is dust-free and the sack needs no sewing afterwards. The valve can be a tuck-in or inserted sleeve, ultrasonically welded, or self-sealing with an adhesive strip, and is combined with a sewn, block or pinch bottom. Used for flour and premix, fine chemicals, minerals and fillers, fertiliser, dry mortar and fine sugar.

Bottom (and often top) is folded and hot-melt or heat sealed rather than sewn, producing a flat, dust-tight, square-shouldered sack that runs on automated lines and looks like a premium paper multiwall.

Processes tape-extrusion · flat-weaving · circular-weaving · roto-print · BOPP-print-laminate · heat-seal · cut-sew

A woven sack that stands up on a shelf like a carton. Bottom is folded, pasted or welded into a rectangle and the sides are creased so the filled bag holds a cuboid shape. This is woven packaging fighting film pouches for shelf space.

Five panels, four vertical corner seals, flat base — the box pouch format, built on a laminated woven substrate instead of film so it can carry 5-15kg without bursting. The direct answer to film quad-seal pet food bags.

A laminated woven retail bag with a carry handle punched through the top of the bag itself, so no separate handle part is needed. Because woven fabric tears easily from a cut edge, the handle area is reinforced with a laminate patch, a folded-over top flap or heat-sealed edges that fuse the cut tape ends, and the opening can be a plain slot, a D-cut, a kidney or oval cut, or twin slots. Common on retail packs of rice, charcoal, potting mix, cat litter, firewood and wild bird seed.

A moulded PP/HDPE handle clipped, riveted or heat-staked through the top hem. Comfortable in the hand at weights where a punched slot cuts fingers, and it reads 'premium' at shelf.

Woven PP webbing or PP strapping tape sewn or ultrasonically welded to the bag as a loop or side handles. The heavy-duty carry solution for 15-25kg retail packs where a punched slot or clip would fail.

A press-to-close (or slider) zip tape welded into the mouth of a laminated woven bag so the consumer can reclose it. The single most-demanded upgrade in premium pet food and litter.

A printed woven bag with a clear area that lets the shopper see the product. There are two constructions: a knock-out window, where an area of the BOPP laminate is left unprinted and the product is seen through the weave, and a patch window, where an aperture is cut in the fabric and clear film is welded over it for near-glass clarity. Windows can be a vertical strip, a full clear front or a shaped cut-out, with anti-fog film for moist products, and are used on retail rice, pulses and speciality grains, dry pet food, seed, lump charcoal, bird seed and potting media.

Bags supplied in wicketed bundles (punched and threaded onto a metal wire) so an automatic bagging machine can strip one bag at a time. Not a bag design so much as a supply format that unlocks automation.

Retail carrier bags made from laminated woven or laminated nonwoven PP — a huge category in India and South Asia for sweets, grocery, garment and promotional bags. Same gravure press, same lamination line as the sack business.

A finish play, not a structure play: matte, soft-touch or paper-textured BOPP that gives an 'eco/artisan' look on a fully plastic, fully waterproof woven sack. Popular where brands want the paper aesthetic without paper's weather failure.

Seed needs to breathe (viability drops in sealed packs), be traceable, and survive a season in a shed. A tension between the moisture barrier lamination gives and the respiration seed needs — solved with micro-perforation or partial lamination.

Charcoal is sharp, dusty, greasy-black and de-gasses — the most abusive retail product in this family. Laminated woven with vents and a handle is the standard answer; the lamination is what stops black dust marking the shopper.

Sugar's spec is dominated by food-contact compliance and moisture control — a PE liner inside a laminated woven sack is the standard global construction from refinery 50kg down to retail 1kg.

Typical Capacity 1, 2, 5, 10, 15, 25, 30, 50, 100kg. Grade A fabric for 50kg (rated 50kg), grade B 40kg, grade C 25kg. Mesh 10×10 or 12×12/inch, fabric 80-120 gsm, BOPP 18-25μm. PE liner 40-80μm food-grade virgin, sealed. FDA 21 CFR 175.105 adhesive; EU 10/2011 or GB 4806 for those markets. Anti-slip lacquer common because refinery pallets are hand-stacked.

Flour is a fine, de-aerating powder that clouds a filling hall — which is why this application drove the move from sewn open-mouth to block-bottom valve sacks. The premium retail end uses laminated woven for shelf appeal.

A bag made from spunbond non-woven fabric laminated with gravure-printed BOPP film. It is often sold under the same 'BOPP laminated bag' name as laminated woven bags, so the substrate should be stated when specifying. It is made up by sewing or ultrasonic welding as a tote, D-cut bag, box bag, foldable shopper, insulated cooler bag or garment cover. Softer and lighter-duty than laminated woven fabric and not suited to heavy sack loads, it is used for retail carriers, promotional and event bags, garment and shoe bags, and insulated grocery bags.

A single-use bag made from LDPE film for packing ice. The film is usually modified to stay tough at freezing temperatures and is clear so the ice can be seen; bags are flexo-printed, heat-sealed and supplied on a wicket for fast filling, or with a drawstring or cotton-string closure. Used for retail bagged ice, convenience-store and forecourt ice, foodservice ice and fishing and marine ice; a laminated woven cooler tote is the reusable woven alternative.
