Transparent Clear Plastic PET/PE Laminated Film For Plastic Food Tray

Transparent PET/PE Laminated Film for Food Trays

HSQY manufactures transparent PET/PE laminated film for thermoformed food trays, form-fill-seal packaging, meat trays, fish trays, poultry packs, cheese packaging, deli products and other chilled food applications.

The material is a semi-rigid thermoformable bottom web consisting of an APET structural layer combined with a PE sealing layer. The PET layer provides transparency, rigidity and forming support, while the PE layer provides heat-sealing functionality and moisture resistance.

The featured product is available in total thicknesses from approximately 0.23mm to 0.58mm. A reference construction uses an approximately 50µm PE sealing layer, while the PET thickness, PE thickness and total laminate structure can be customized according to the tray design and packaging line.

Clear rolls can be supplied on 3-inch or 6-inch paper cores with customized roll width, roll length, roll weight, outside diameter and winding direction.

Peelable and weld-seal packaging options can be developed according to the selected lidding film, sealing temperature, dwell time, pressure, tray-flange design and required opening force.

Standard PET/PE provides clear presentation, thermoformability and reliable sealing. Products requiring extended shelf life, modified atmosphere packaging or a specified high oxygen barrier should use a structure with verified OTR and WVTR values, such as PET/EVOH/PE where appropriate.

What Is PET/PE Laminated Film?

PET/PE laminated film is a multilayer packaging material that combines a rigid or semi-rigid polyethylene terephthalate layer with a polyethylene sealing layer.

APET provides the primary structure, stiffness, transparency and thermoforming support. PE provides a sealable food-contact surface, moisture resistance and additional toughness.

During thermoforming, the heated laminate is drawn into cavities to create trays or bottom packs. Food is then loaded into the formed cavities and a compatible top film is sealed to the tray flange.

The material may also be described as APET/PE bottom web, rigid PET/PE film, PET/PE thermoforming roll, clear tray-forming film or PET/PE form-fill-seal film.

PET/PE Thermoforming Bottom Film vs. Lidding Film

This product is primarily positioned as a thermoformable PET/PE bottom web or tray-forming material rather than a conventional flexible lidding film.

APET/PE Laminated Film Specifications

Final specifications should state the complete layer structure, total thickness, individual layer thicknesses, width tolerance, roll length, core diameter, outside diameter, winding direction, optical quality, barrier values and sealing requirements.

PET and PE Layer Functions

Peel Seal vs. Weld Seal Packaging

Peel or weld performance is created by the complete package system. The bottom web, lidding film, sealant layers, tray flange, product contamination, temperature, pressure and dwell time must be validated together.

Thermoforming Performance Requirements

Heating Uniformity

The PET/PE laminate should heat evenly across the web to reduce local overstretching, wrinkles and incomplete forming.

Forming Depth and Draw Ratio

Deep cavities, narrow corners and high draw ratios may require a thicker PET layer, optimized mold radii, plug assistance or pressure forming.

Wall-Thickness Distribution

Formed corners and sidewalls should retain sufficient thickness to resist puncture, cracking and deformation during filling and transport.

Layer Adhesion

PET and PE layers must remain bonded during heating, stretching, trimming, sealing, chilling and package opening.

Mold Release and Denesting

Mold draft, surface friction and stacking geometry affect release from the mold and separation of finished trays.

Trimming and Scrap Handling

The formed laminate should trim cleanly without excessive burrs, uncontrolled cracking or delamination at the cut edge.

Standard and High-Barrier PET/PE Structures

OTR, WVTR and MAP Requirements

Barrier performance should be expressed using measured values rather than general descriptions such as excellent or superior barrier.

Test conditions, including temperature and relative humidity, must be stated together with every barrier value.

Applications of PET/PE Laminated Film

• Fresh meat trays: Clear thermoformed packs for beef, pork and processed meat.

• Poultry packaging: Trays and form-fill-seal packs for chicken and other chilled poultry.

• Fish and seafood: Clear packs requiring moisture resistance, puncture resistance and seal integrity.

• Cheese packaging: Sliced, grated, block and portioned cheese products.

• Deli foods: Prepared meats, salads, antipasti and cold ready-to-eat products.

• Fresh produce: Fruit, vegetables, mushrooms and prepared produce.

• Bakery and confectionery: Clear trays and display packaging for chilled or ambient products.

• Modified atmosphere packaging: High-barrier structures developed for the required gas mixture and shelf life.

• Vacuum packaging: Pack designs requiring strong seals and controlled material distribution.

Chilled, Frozen and Temperature Requirements

PET/PE laminated trays are commonly developed for chilled and selected frozen foods, but the exact service-temperature range must be validated for the approved structure.

Low-temperature impact, tray cracking, seal strength, delamination and drop performance should be tested after the required cold-storage period.

Standard APET/PE should not automatically be described as suitable for microwave heating, conventional ovens, retort processing or high-temperature pasteurization.

Products requiring heat resistance should use a structure specifically developed and tested for the intended temperature, duration and heating method.

Food-Contact and Regulatory Requirements

Food-contact suitability depends on the PET resin, PE resin, adhesive or tie layer, additives, recycled content, colorants and manufacturing process.

Buyers should identify the destination country, food type, contact temperature, contact duration, refrigeration conditions and whether the food is fatty, acidic, alcoholic, dairy-based or aqueous.

Available documentation may include food-contact declarations, overall and specific migration reports, resin declarations, restricted-substance reports and quality-management certificates.

An SGS report should be described according to the exact test completed and does not automatically establish compliance in every country or application.

RoHS relates primarily to restricted substances in electrical and electronic equipment and should not be used as the principal evidence for food-contact safety.

Pharmaceutical and Medical Packaging

Pharmaceutical and medical applications require a separately controlled PET/PE grade rather than a general food-tray specification.

The buyer should identify the packaged product, sealing material, sterilization method, cleanliness requirements, extractables, migration requirements and package-validation standard.

The complete medical or pharmaceutical package must be validated after forming, sealing, sterilization, transport and shelf-life testing.

PET/PE Laminate Recyclability

PET and PE are different polymer families, so a PET/PE laminate should not automatically be described as a mono-material or universally recyclable package.

Recycling compatibility depends on the PET percentage, PE percentage, adhesive, EVOH or other functional layers, color, labels, printing and the recycling system used in the destination market.

Predominantly PET structures with carefully controlled non-PET layers may provide better compatibility with PET thermoform recycling systems, but the completed package should be evaluated against applicable design-for-recycling guidance.

The most accurate claim is that recyclability must be assessed using the complete laminate structure and the collection, sorting and recycling infrastructure available locally.
