What Is PET/PE Laminated Film?

PET/PE laminated film is a multilayer rigid or semi-rigid packaging material consisting of a PET-based structural substrate and a polyethylene heat-sealing layer.

It may also be described as APET/PE film, PET/PE bottom web, PET laminated PE sheet, PET/PE composite sheet or PET/PE thermoforming rollstock.

This product is primarily designed as a thermoforming bottom web rather than a thin flexible pouch film. During production, the web can be heated and formed into trays or cavities before filling and sealing with a compatible lidding material.

How the PET/PE Structure Works

PET Structural Layer

The PET layer provides the structural body of the material. It supports transparency, rigidity, impact resistance and dimensional stability during thermoforming, filling, sealing, transportation and retail handling.

PE Heat-Sealing Layer

The PE layer provides a sealable surface that can bond with compatible PE-based lidding films under controlled heat, pressure and dwell time. It also contributes flexibility and moisture resistance.

Laminated Construction

Combining PET and PE allows the bottom web to provide forming rigidity and heat-sealing functionality in one structure. The appropriate layer ratio depends on tray depth, product weight, sealing system and package-performance requirements.

PET/PE vs. PET/EVOH/PE

Standard PET/PE and high-barrier PET/EVOH/PE are designed for different packaging requirements. The correct structure should be selected according to oxygen sensitivity, shelf-life target, gas environment, sealing system and storage conditions.

If oxygen transmission is critical, provide the target OTR, storage temperature, humidity, gas mixture and shelf-life requirement so the appropriate standard or high-barrier structure can be evaluated.

Peelable vs. Weld-Seal PET/PE Film

Peelable Grade

A peelable structure is designed to maintain package integrity during storage and distribution while providing controlled opening by the user. Peel strength should be evaluated with the actual lidding film and sealing equipment.

Weld-Seal Grade

A weld-seal grade is intended for applications requiring a stronger permanent bond. Seal strength and package integrity should be validated using the actual lidding film, tray flange and sealing parameters.

Matched Lidding Film

The thermoformed bottom web and lidding film should be evaluated as one packaging system. Confirm sealant compatibility, sealing temperature, pressure, dwell time and required opening force before commercial production.

How PET/PE Film Is Used in Thermoform-Fill-Seal Packaging

Heating

The PET/PE bottom web is heated to an appropriate forming condition according to material thickness, PET grade, heater design and line speed.

Forming

Vacuum, pressure or plug-assisted forming draws the heated web into the mold. Tray depth and corner geometry influence the final wall-thickness distribution.

Filling

The formed cavities are filled with the intended food or packaged product.

Sealing

A compatible top web is sealed to the PE layer under controlled heat, pressure and dwell time.

Cutting and Separation

The sealed packs are trimmed and separated according to the thermoforming-line configuration.
