As the pet food industry continues to expand globally, the demand for durable, reliable, and safe packaging solutions has never been higher. Woven Bags with PE Liner have emerged as a leading option in this field, offering the strength of woven polypropylene combined with the protective properties of polyethylene (PE) liners. These bags are particularly well-suited for packaging dry pet foods like dog and cat food, where maintaining product freshness, protecting against contamination, and ensuring durability during transport are critical. At VidePak, we specialize in producing high-quality Woven Bags with Liner that meet these exacting standards, offering our clients in the pet food industry the peace of mind that their products are well-protected from the moment they leave the production facility to the time they reach the consumer.
What Are Woven Bags with PE Liner?
Woven Bags with PE Liner are polypropylene (PP) woven sacks paired with an internal polyethylene (PE) liner to protect dry pet foods—kibble, treats, premixes—from moisture ingress, fat migration, and odor loss. The woven textile gives mechanical strength; the liner adds a continuous barrier and a clean contact surface. In different markets you may also hear woven poly bags with PE liner, PE‑lined PP woven sacks, liner‑insert poly woven bags, or coated woven pet‑food bags—different names, one clear intent: a bag that carries like a workhorse and presents like a brand, while keeping pet nutrition fresh and floors clean.
Unlike plain paper sacks that wilt in drizzle or mono‑film PE bags that tend to slip on pallets, Woven Bags with PE Liner sit in the productive middle ground. The warp and weft tapes share loads like an engineered textile; coatings and liners create a layered defense against humidity and dust; seam architecture ensures fines stay inside. For retailers that judge with the eye, the exterior can be finished with high‑fidelity prints or BOPP laminates; for operators that judge with the stopwatch, the square, predictable body feeds neatly on automated lines.
What Are the Features of Woven Bags with PE Liner?
Moisture control you can dial in. Pet food is hygroscopic and fat‑bearing—two reasons moisture discipline matters. Woven Bags with PE Liner use an inner film (typically 40–80 μm LDPE or co‑ex PE) to reduce water‑vapor transmission and preserve aroma. Need more insurance for coastal or monsoon corridors? Pair the liner with a thin outer LDPE/PP coating (≈ 18–30 g/m²) on the woven fabric to close inter‑yarn pores and enable heat‑sealing or pinch‑bottom closures.
Strength without dead weight. The woven PP lattice distributes puncture and tear loads across warp and weft. Result: corners stay crisp, seams stay shut, pallets stay square—even when bags meet clamp trucks, epoxy floors, or steel forks. You gain durability without paying a freight penalty for over‑gauge material.
Leak‑resistant seams and clean handling. Kibble sheds fines; premixes can sift. Anti‑sift bottom constructions—crepe‑taped stitching with hot‑melt, folded/locked hems, or ultrasonic sealing on coated builds—block the micro‑pathways where powders tend to escape. Cleaner aisles in the DC, fewer complaints at the shelf.
Food‑contact confidence. Polymer elements in Woven Bags with PE Liner can be specified to align with GB 4806.7, FDA 21 CFR 177.1520 (olefin polymers), and EU 10/2011 when required. We regularly verify print rub (ASTM D5264 / TAPPI T 830), drop (ASTM D5276), compression (ASTM D642), and WVTR (ASTM E96 / ISO 15106) so marketing claims travel with test numbers.
Brand‑forward graphics that survive the route. Surface flexo supports 1–6 colors for logos, nutrition panels, and handling icons. For photo‑grade storytelling, reverse‑printed BOPP (15–25 μm; matte, gloss, or pearlized) can be laminated so the artwork sits protected under film—shiny where you want allure, matte where you want reading ease. Your panels persuade; your panels arrive intact.
Grip where it matters. Smooth films can skate; woven textures grip. Woven Bags with PE Liner naturally raise pallet friction versus mono‑film alternatives. Add printed anti‑slip stripes or matte patches when automation or high‑bay racking makes stability non‑negotiable.
Sustainability with substance. By tuning tape denier, mesh, and coating weight, we avoid over‑engineering. Mono‑material paths (PP fabric + PP/PE liner that is easily separable) make downstream handling more straightforward where recycling streams exist. Durability cuts rebagging and stretch‑wrap consumption—a quiet win for cost and carbon.
What Is the Production Process of Woven Bags with PE Liner?
Extrusion & drawing—strength begins in the tape. Virgin PP pellets are melted, extruded as a thin sheet, slit into tapes, and drawn to orient polymer chains. The draw ratio sets tape denier (commonly 700D–1200D for bag fabrics). Too little draw invites stretch and stress‑whitening; too much risks brittleness. The sweet spot gives Woven Bags with PE Liner a backbone that resists puncture yet forms cleanly on the shoulder.
Weaving—creating the biaxial lattice. Tapes interlace on circular looms to form tubular or flat fabric. Mesh density (≈ 10×10–14×14 tapes/inch) balances flexibility and venting against fines control and smooth print lay‑down. Tight tolerance on tube width and gusset depth keeps bags feeding predictably on automated fillers.
Surface engineering—coating and corona. Where humidity swings or sift resistance is required, an LDPE/PP coating (≈ 18–30 g/m²) is extrusion‑applied to close inter‑yarn pores and create a heat‑seal interface. Corona treatment lifts surface energy so inks and hot‑melts anchor reliably in both coated and laminated constructions.
Liner fabrication & insertion—second‑wall protection. The PE liner (clear or black) is either gusseted and inserted as a loose sleeve, tab‑fixed to the neck, or manufactured as a form‑fit liner tailored to the bag’s internal cube. Black liners add light/UV blocking for photosensitive vitamins in fortified kibbles and also help with privacy in retail back rooms.
Printing & conversion—identity meets utility. Surface flexo or reverse gravure (for BOPP laminates) is run to spectrophotometric color targets so reorders match approved artwork. The web is gusseted, cut to length, and closed by sewing (breathable builds) or by heat‑sealing/pinch‑bottom (coated builds). Easy‑open tear tapes are available for consumer convenience; reclosable features can be engineered into secondary packaging if desired.
Quality control—turning promises into proof. Inline gauges track tube width, gusset depth, squareness, registration, and stitch density. Off‑line labs verify drop, compression, rub, seal strength, and—when specified—WVTR/odor retention. Certificates of Analysis map each result to the SKU so audits move on data, not anecdotes.
What Is the Application of Woven Bags with PE Liner?
Dog and cat kibble (5–25 kg). Kibble carries oils that migrate and aromas that sell. Woven Bags with PE Liner pair a grease‑tolerant inner wall with scuff‑resistant exteriors, keeping flavors inside and branding outside. Anti‑slip finishes make high‑bay racking calmer; crisp barcodes keep WMS scans fast.
Pet treats and biscuits. Brittle, shaped pieces demand abrasion resistance and tidy seams. Leak‑controlled bottoms prevent crumb trails in cases; matte BOPP zones improve panel readability for nutrition and claims.
Feed premixes & supplements. Vitaminized blends and probiotics are often light‑ and moisture‑sensitive. Black PE liners add opacity; outer coatings lower WVTR; pinch‑bottom geometry boosts leak resistance for fines.
Aquaculture & specialty species. Sinking and floating pellets benefit from cubic stacks and predictable handling across barge, truck, and warehouse nodes. Woven Bags with PE Liner maintain unit‑load integrity so protein gets where it should, how it should.
E‑commerce & club formats. Large‑format pet food SKUs must look premium after long routes. Reverse‑printed BOPP delivers shelf‑grade graphics; woven cores shrug off conveyor rub and clamp cycles, keeping returns down and reviews up.

The Advantages of Woven Bags with PE Liner for Pet Food Packaging
Woven Bags with PE Liner provide a unique combination of durability, flexibility, and protection that is ideally suited for pet food packaging. The outer layer of the bag is made from woven polypropylene, which is known for its strength, resistance to punctures, and ability to withstand the rigors of handling and transportation. This ensures that the bags can handle the heavy loads often associated with large quantities of pet food, reducing the risk of tearing or other damage that could compromise the integrity of the product.
The inner PE liner adds an additional layer of protection, acting as a barrier against moisture, air, and contaminants. This is particularly important in the packaging of dry pet foods, where exposure to humidity or air can lead to spoilage or the loss of nutritional quality. By using Liner PE Bags, manufacturers can ensure that their pet food products remain fresh and safe for consumption over extended periods, even in challenging storage or transportation conditions.
Moreover, the Woven Bags with PE Liner are designed to be highly versatile and customizable, allowing for a range of options in terms of size, shape, and closure methods. This flexibility is essential in the pet food industry, where packaging needs can vary widely depending on the type of food, the size of the packaging, and the specific requirements of different markets. At VidePak, we offer a wide range of customization options to meet these needs, ensuring that our clients receive packaging solutions that are perfectly tailored to their products.
The Role of Aluminum Liner Bags in Pet Food Packaging
In addition to PE Liner Bags, Aluminum Liner Bags have also gained popularity in the pet food industry due to their superior barrier properties. Aluminum liners provide an even higher level of protection against moisture, oxygen, and light, making them ideal for packaging pet foods that are particularly sensitive to these factors. For example, premium dog or cat foods that contain high levels of fats or oils can benefit from the enhanced protection offered by aluminum liners, which help prevent oxidation and the subsequent loss of flavor and nutritional value.
While Aluminum Liner Bags may be more expensive than standard Liner PE Bags, they offer significant advantages in terms of product protection and shelf life. This makes them an excellent choice for high-end pet food products where maintaining quality and freshness is paramount.
