1. High Barrier Properties

Superior Protection: High barrier against moisture and oxygen.

Water Vapor Transmission Rate (WVTR): ≤ 0.5 g/m²·24h

Oxygen Transmission Rate (OTR): ≤ 0.5 cc/m²·24h

2. Specialized Sealing Performance 

Seal-Through-Contamination: The inner layer seals securely even through powder contamination.

Knurled Sealing Compatible: The outer layer withstands high temperatures, ensuring smooth operation with knurled sealing jaws without sticking.

3. Optimized Surface for Coding 

Enhanced Ink Adhesion: The outer layer features a specialized coating (or matte finish) designed to maximize the clarity and durability of subsequent coding (e.g., inkjet batch numbers, expiry dates).

Durable Markings: Ensures that variable data codes remain clear, complete, and resistant to rubbing off during handling.
