Features of PA/PE Film in High-Barrier Packaging

Feature Benefit

Oxygen Barrier PA layer significantly reduces O₂ permeation → extends shelf life of sensitive products (e.g., snacks, coffee, pharmaceuticals)
Moisture Barrier PE layer prevents moisture ingress → protects hygroscopic goods 
Grease & Oil Resistance Ideal for fatty or oily foods (e.g., fried snacks, meat products) 
Mechanical Strength Resistant to tearing during handling and transportation 
Heat Sealability PE surface allows reliable sealing at high speeds 
Process Flexibility Can be converted into pouches, wraps, sachets, and stand-up bags |Types of PA/PE Films

Description
Mono-layer PA/PE Simple lamination; less common due to limited barrier
Multi-layer (e.g., PA/PE, PA/AL/PE) Enhanced barrier with aluminum foil (Al) or EVOH (Ethylene Vinyl Alcohol) added for even better gas barrier
Co-extruded PA/PE Simultaneous extrusion of layers for improved adhesion and consistency
Printable PA/PE Surface-treated for ink adhesion (e.g., corona treatment)
