Our zipper bags are manufactured from premium PE (Polyethylene), PP (Polypropylene), and EVA (Ethylene-Vinyl Acetate) materials,
designed to provide safe and convenient storage for a wide range of products, including food, apparel, pharmaceuticals, and industrial components.
Each material has unique advantages: PE is soft and flexible, ideal for refrigerated and frozen storage; PP offers high rigidity and heat resistance for microwave defrosting and high-temperature sterilization; EVA provides excellent sealing and transparency for premium packaging.

Produced through precise film extrusion and converting processes, our zipper bags come in a variety of shapes and designs,
including flat type, stand-up pouches, wing type, and slider type.
The zipper closure options include single-track, double-track, waterproof sliders, and wing zippers compatible with automatic packaging machines..

Anti-fog film to prevent condensation in refrigerated or frozen environments

Freshness-preserving mineral additives to strengthen oxygen and moisture barrier properties

Integration with high-barrier films (Al, EVOH, etc.) for extended shelf life
These features make our zipper bags ideal for packaging food, coffee beans, tea, clothing, electronics, and more.

For sustainability, we actively adopt single-material designs and recyclable materials, while offering full customization in thickness, size, printing, color, and transparency.
This allows us to deliver high-quality, functional, and eco-friendly zipper bags that meet the diverse needs of markets worldwide.
