PET/PE Packaging Film

PET/PE (Polyethylene Terephthalate/Polyethylene) Packaging Film is a high-performance composite packaging material engineered by laminating PET film as the base layer and PE film as the heat-sealing layer. This unique composite structure combines the superior mechanical strength and barrier properties of PET with the excellent heat-sealing performance and flexibility of PE, making it a versatile and reliable solution for a wide range of packaging applications across multiple industries.

Product Overview

The PET/PE packaging film is manufactured through advanced dry lamination or extrusion lamination technology, ensuring strong adhesion between the PET and PE layers. The PET base layer provides structural stability, excellent puncture resistance, and good barrier against oxygen and light, while the PE heat-sealing layer offers easy processability, strong sealing strength, and good chemical resistance. The film features a smooth surface, uniform thickness, and consistent physical properties, adapting to various packaging processes such as heat sealing, printing, die-cutting, and bag making. It is available in different specifications (thickness, width) and can be customized with additional treatments like matte finish, glossy finish, or anti-fog coating to meet specific application needs.

Core Advantages

Exceptional Composite Performance: By laminating PET as the base layer and PE as the heat-sealing layer, this film synergizes the inherent strengths of both materials. The PET base delivers outstanding tensile strength (longitudinal ≥ 150 MPa, transverse ≥ 100 MPa) and puncture resistance, effectively safeguarding packages against damage during transportation and handling. Meanwhile, the PE layer enables reliable heat sealing, forming airtight and leak-proof seals even at moderate temperatures—ensuring consistent packaging integrity.
