Enhanced Adhesion for Critical Lamination: CaiLong’s Metallized PET film with precoating features a specialized chemical primer layer on the Al surface. This engineered coating significantly boosts bonding strength (>2.5 N/15 mm) between the metal layer and various polymers (e.g., PE, PP, PET), effectively preventing common delamination issues such as "Al flaking" or "metal peeling" during high-temperature retort processing or long-term storage.
Core Performance
-
Superior Cohesion: Ensures uniform adhesion across the entire film surface, critical for high-speed automatic lamination lines.
-
Retort Durability: Maintains hermetic seals and visual integrity under harsh sterilization conditions (high heat and pressure).
-
Consistent Barrier: Preserves the excellent OTR (Oxygen Transmission Rate) and WVTR (Water Vapor Transmission Rate) properties of standard VMPET while adding the lamination benefit.
-
Process Flexibility: Compatible with various converting processes including slitting, sheeting, and printing.
Typical Applications
-
Liquid food packaging (e.g., retort pouches, spout pouches, stand-up pouches).
-
Pharmaceutical blister packaging requiring high barrier and seal integrity.
-
Industrial laminates where strong chemical resistance and long-term durability are mandatory.
