Product Structure & Layer Functionality

• PA (Nylon) Barrier Layer: The outer or core PA layer provides outstanding oxygen, aroma, and gas barrier properties, effectively preventing oxidation and flavor loss to extend product shelf life. It also delivers exceptional puncture resistance, tensile strength, and dimensional stability, protecting products from sharp edges (such as meat bones) and impact during transportation and freezing.
• Tie Layer: A specialized adhesive tie layer ensures permanent bonding between the dissimilar PA and PE materials, preventing delamination even under extreme temperature fluctuations, high-heat processing, or long-term storage.
• PE Sealant Layer: The inner PE layer offers excellent flexibility, moisture barrier, and reliable, consistent heat-sealing performance. It enables airtight, leak-proof seals for vacuum, modified atmosphere (MAP), and standard packaging applications, while also providing resistance to moisture and oils.
