Properties:

• High-strength polyester with excellent rigidity
• Superior dimensional stability and moisture resistance
• Maintains structural integrity under stress
• Good chemical resistance against weak acids and solvents
• Smooth surface enhances printability for branding

Function:

Primary protective layer shielding inner materials from mechanical abrasion and environmental exposure. Hardness and rigidity prevent punctures and tears during handling.

Properties:

• Exceptional impermeability to light, oxygen, and moisture
• Absolute barrier against external contaminants
• Reflective surface helps regulate internal temperature

Function:

Core barrier layer blocking UV rays, air, and humidity that could degrade sensitive materials. Ensures contents remain pristine.

Properties:

• Tough polymer with high tensile strength
• Excellent abrasion resistance and flexibility
• Withstands repeated stress without cracking
• Good heat stability

Function:

Enhances puncture resistance and durability, making the bag robust against rough handling. Flexibility allows the bag to maintain shape under load.

Properties:

• Excellent flexibility and moisture resistance
• Superior heat-sealability for strong bonds
• Soft texture protects contents from internal abrasion

Function:

Inner sealing layer facilitates easy heat-sealing or adhesive bonding, creating a secure enclosure and leak-proof protection.
