Sino Topway manufactures and exports moisture resistant woven poly bags that are purpose-built for animal feed, grains, fertilizers, and industrial powders. These aren't typical poly shopping bags-they are high-strength, laminated or lined packaging sacks made from woven polypropylene, offering unmatched protection in wet or humid environments.
Whether you're a distributor, importer, or feed brand, our custom poly woven sacks offer multiple moisture barrier options-including BOPP lamination, inner PE lining, and paper poly layers-to preserve product quality during storage and transit.
I. Packaging That Shields Against Moisture-From the Inside and Outside
Moisture control is critical in bulk packaging. That's why our woven poly bags are engineered with layered barrier systems to stop spoilage, mold, and clumping before it starts.
Moisture Protection Options:
● BOPP Laminated Poly Bags
Biaxially Oriented Polypropylene (BOPP) film laminated on the outside for an oxygen and vapor barrier, plus vivid branding.
● PE Film Inserted Sacks
A full PE liner inserted inside the woven sack for direct protection of loose or powdery materials like feed additives or fertilizers.
● Inner-Laminated Woven Sacks
An internal moisture-resistant layer fused inside the PP fabric, ideal for finer powders that need sealing without a loose liner.
● Paper Poly Woven Bags
Popular in North America, this option bonds kraft paper to woven poly for a traditional look with high strength and shelf appeal.
II. Built for Bulk Performance – Not Retail Totes
Unlike retail poly bags or reusable shopping totes, these poly woven sacks are made for industrial-scale use. Each sack is:
- Tear-resistant for handling heavy contents like feed, charcoal, or minerals
- UV-treated (optional) for outdoor exposure
- Available with ventilation via micro-perforation
- Printable in up to 10-color full-panel gravure designs
- Stack-friendly with options like block bottom or anti-slip coating
III. Ideal for Packaging
- Animal Feed: Poultry feed, horse pellets, ruminant nutrition
- Pet Food: Dog and cat kibble, birdseed
- Grains & Seeds: Rice, corn, soy, barley, wheat
- Fertilizer: Urea, organic blends, powdered nutrients
- Charcoal & Firewood: Briquettes, lump coal, wood pellets
- Industrial Powders: Food additives, resins, minerals, and more
