Vacuum bags are widely used in food preservation and industrial packaging applications. Produced using high-performance PA/PE co-extruded films, they provide excellent barrier protection, durability, and long shelf life. These bags help maintain product freshness by minimizing oxygen exposure and protecting against external contamination.
Production Technology
PA/PE films are manufactured using co-extrusion technology, creating a multi-layer structure that combines the advantages of both materials. This structure typically consists of one polyamide (PA) layer combined with one or more polyethylene (PE) layers, providing strength, flexibility, and reliable barrier performance.
Applications
Vacuum bags are commonly used for:
Meat
Cheese
Seafood
Frozen Food
Industrial Parts
Medical Products
