Composite Plastic Bags
Products Description
Preserve Flavor and Freshness
Pet snacks, coffee powder, and spices need protection from air and moisture. The Composite Plastic Bags from JUNTENG PACKAGING CO., LTD. are made for this purpose. These bags use multiple layers of laminated material to provide strong protection. Common structures include PET/PE, PET/VMPET/PE, and NY/PE. The PET layer gives the bag stiffness and a good surface for printing. The metallized layer blocks light and oxygen. The nylon layer adds puncture resistance. The PE layer provides a strong heat seal. Different products need different levels of protection. We recommend the right structure for your product. The Composite Plastic Bag helps keep your product fresh and protected for longer.
