PET PE Laminated Film
- Material:PET / PE laminated structure
- Appearance:Clear, glossy, or slightly matte
- Thickness:40-300 um by grade
- Width:200-1600 mm, standard slit tolerance +/- 2 mm
- Seal Type:Easy peel, weld seal, or lock seal
- Main Use:Tray lidding and thermoforming food packaging
Protective Film Rolls Company is a manufacturer of pet pe laminated film for tray lidding, thermoforming sheet, and food packaging applications. This PET/PE food packaging film combines a clear, printable PET support layer with a PE heat seal layer for sealing to compatible tray rims or formed structures. It is made for packs that need stable unwinding, clean sealing, controlled peel force, and reliable performance for chilled meals, seafood, cheese, bakery products, fresh produce, and prepared foods.
Product Overview
PET/PE laminated film is used where packaging needs PET stiffness and clarity, but also requires PE sealing behavior. In a typical PET PE laminate film, the PET side helps the web stay flat during printing, slitting, cutting, tray sealing, and storage. The PE side bonds with PE-coated trays, APET/PE trays, and other compatible tray rims.
Common lidding grades often use 12-36 um PET with a 30-100 um PE seal layer, while thicker APET/PE sheet can be produced for forming webs or tray sheets. In our production checks, standard clear grades are commonly controlled within +/- 2 mm width tolerance, with 38-44 dyn corona treatment on the PET side. The practical heat seal range is usually 120-160 C, depending on PE formulation, tray rim material, pressure, dwell time, and tray cleanliness.
Benefits
- Stable tray presentation:PET stiffness helps reduce curling during sealing, cutting, storage, and display.
- Reliable heat sealing:The PE layer supports rim sealing, peel control, and leak resistance.
- Clear food visibility:The clear PET surface supports chilled meals, fresh food, bakery packs, and seafood trays.
- Flexible seal options:Easy peel suits smooth opening, while weld seal or lock seal supports stronger protection.
- Line compatibility:Thickness, COF, seal layer thickness, roll width, and core size can be adjusted for tray sealers, thermoforming lines, and form/fill/seal equipment.
When Should PET/PE Laminated Film Be Used for Tray Lidding?
This structure fits trays that need a clear top web and a controlled seal around the rim. It is often used for ready meals, cheese portions, seafood trays, salad bowls, bakery trays, and fresh produce packs where shelf appearance and sealing reliability both matter. For liquid content, cold-chain handling, or higher transport stress, weld seal or lock seal performance should be checked by sample testing before mass production.

Applications
- Lidding for chilled ready meals, salad bowls, seafood trays, meat packs, and cheese portions.
- Clear APET/PE sheet for thermoformed trays that need tray stiffness and a sealable PE surface.
- Laminated food packaging for bakery items, dry foods, frozen portions, and packs needing clear display with heat-sealable performance.
- Heat-sealable rollstock for automatic tray sealing lines that require stable temperature, smooth unwinding, clean cutting, and low edge lifting.
- Printed PET/PE structures for packaging that needs clear display, a printable PET surface, and PE-based rim sealing.
How Does the PE Heat Seal Layer Affect Packaging Line Performance?
The PE heat seal layer directly affects how the film runs on the packaging line. If it is too soft, too thin, or not matched with the tray rim, the pack may show weak seals, edge lifting, stringy peel, poor hot tack, or uneven opening force. During sample validation, sealing temperature, dwell time, jaw pressure, tray cleanliness, rim flatness, PE layer thickness, and COF should be checked together.

FAQ
What is the difference between PET/PE laminated film and PA/PE film?
PET/PE focuses on PET stiffness, clarity, printability, dimensional stability, and PE heat sealing. PA/PE is usually selected for puncture resistance, vacuum packaging, or MAP performance.
Can this film be used as both lidding film and thermoforming sheet?
Yes. Thin rollstock is used for lidding, while thicker APET/PE sheet can be made for formed trays and bottom web structures.
How do I choose easy peel or weld seal?
Use easy peel for smooth opening. Use weld seal or lock seal when stronger sealing is needed during cold storage, transport, or liquid-containing applications.
Can food contact documentation be supplied?
Yes. Protective Film Rolls Company can provide food-contact documentation according to target market and material structure. Final suitability should be confirmed by sample testing on the actual tray, packed food, and sealing line.
