Shandong Lepu Digital Printing Co., Ltd. is one of the most reliable manufacturers and suppliers of compostable packaging bags in China. With abundant experience, we warmly welcome you to wholesale high quality compostable packaging bags from our factory. Customized orders are welcome.
Compostable Packaging Bags Built for a Plastic-Free Supply Chain
Retailers and regulators are moving fast on single-use plastic bans, and a bag that only claims "eco-friendly" without certification won't clear an audit. These compostable packaging bags are made from certified PLA/PBAT film that fully breaks down in industrial composting facilities, leaving no microplastic residue behind. Beyond the environmental credentials, the matte-finish surface and stable barrier performance make them a practical wholesale replacement for everyday retail bags, mailers, and dry goods packaging - not just a marketing gesture.

Key Features & Advantages of LepuPouch Compostable Packaging Bags
Verified Industrial Compostability: Certified to EN 13432 and ASTM D6400 by TÜV Austria's "OK compost INDUSTRIAL" mark, these bags break down into water, CO₂, and biomass within 180 days under industrial composting conditions - with no microplastic residue, satisfying plastic-ban compliance requirements across Europe and North America.
Barrier Performance on Par with Conventional Film: The optimized PLA/PBAT structure delivers oxygen and moisture barrier levels close to standard laminates, keeping dry goods like coffee, tea, and spice powders fresh for up to 12 months without switching back to non-compostable plastic.
Production-Line Ready Sealing: A heat-seal strength above 35N/15mm and a wide sealing window mean LepuPouch's compostable film runs reliably on high-speed VFFS/HFFS filling equipment, keeping leaker rates below 0.3% and minimizing production downtime.
