Co-ex PE Film
Multi-Layer Supply PE Film is a high-performance functional polyethylene film produced by 3/5/7-layer co-extrusion technology. Adopting layered functional resin formula, each layer independently undertakes heat-sealing, toughness reinforcement, barrier and printing support functions. It integrates the advantages of stable heat-sealing, high toughness, excellent moisture resistance and uniform physical properties, supporting continuous and stable supply for high-speed automated packaging lines. It is widely used in food, pharmaceutical, daily chemical and industrial packaging fields.

Key Features
Stable Multi-Layer Supply Performance
Adopts integrated co-extrusion one-time forming process, no adhesive bonding, uniform film thickness and stable tension. It effectively solves the problems of jitter and material breakage in high-speed continuous supply, ensuring consistent packaging quality in batch production.
Reliable Heat-Sealing Property
Low seal-initiation temperature, wide heat-seal window, firm seal, moisture-proof, no leakage, stable hot-tack for high-speed packaging lines.
High Toughness & Moisture Resistance
Excellent tensile and tear resistance, good moisture barrier, suitable for cold storage and normal-temperature storage.
Good Printability & Lamination Compatibility
Corona-treated surface with high surface tension, clear printing effect; stable bonding with various substrates, no bubble, no delamination after long-term storage.
Good Processability
Smooth running on high-speed bag-making and laminating machines, stable slip performance.
Food-contact Grade Available
Meet food contact standards, non-toxic and odorless for food and pharmaceutical packaging.
