Polyester + White PE + Aluminum + PE (White Triplex Lamination)

Polyester (PET) + PE + Aluminum + PE, known as Silver Triplex, is a multi-layer flexible packaging material designed for applications requiring high barrier protection and maximum durability.

The aluminum layer provides excellent protection against light, moisture, and oxygen, while the dual PE layers ensure strong sealing performance and chemical resistance. The polyester (PET) layer offers high mechanical strength and superior print quality.

It is especially preferred for liquid and alcohol-based product packaging.
