Detailed Description
It is suitable for most food packaging composite films. The heat sealing temperature is moderate. The open side feels tighter, and the other side feels stronger. For two-layer materials, the three-layer material structure can be adapted to the heat sealing on the bag making machine.
Suitable for seafood dry goods, large tea bags, tea bags, gift bags, candy bags, nut bags, and snacks. The tightened PE zipper concave and convex buckle has a relatively large strength, which is suitable for larger bags.
Our factory has professionals, with independent design and certain research and development capabilities, can be customized, can also provide sample mold production.

Frequently Asked Questions (FAQ)
Q What composite film structures are compatible with this PE zipper?
This 12.5mm PE zipper integrates seamlessly with most food packaging composite films on standard bag making machines, including multi-layer structures such as ET+VMPET+PE, PET+PE, and BOPP+PE.
Q Why is this zipper specifically recommended for larger bags?
It features a reinforced concave and convex buckle mechanism that provides superior structural strength and holding power compared to standard PE zippers, holding up under the weight of larger packaging formats.
Q Is this zipper profile suitable for moisture-sensitive products?
Yes. Thanks to its enhanced sealing profile, it is well-suited for high-moisture barriers, protecting high-humidity food, vacuum-packed goods, moisture-sensitive electronics, and industrial raw materials.
Q What are the recommended heat-sealing conditions?
The PE zipper operates at a moderate heat sealing temperature, ensuring smooth, flat sealing without distortion, keeping pouch edges neat and production lines efficient.
Q Can the zipper specifications or mold design be customized?
Yes, our facility has independent design and professional R&D capabilities. We provide custom specifications, tailored material formulations, and sample mold production upon request.
