Oxygen barrier protection
Chemical resistance
Heat resistance
Gloss enhancement
Matte finishes
Printability
Scratch resistance
Anti-fog properties
Heat sealability
Slip control
UV protection
Grease resistance
Antimicrobial functionality

Without high-performance coatings, many modern flexible packaging applications simply would not meet today’s performance standards.
