What Is High-Barrier PET/EVOH/PE Lidding Film?
High-barrier PET/EVOH/PE lidding film is a multilayer tray-sealing film developed for food packages that require reduced oxygen transmission, secure sealing, and stable performance on modified atmosphere packaging lines. A PET or BOPET outer layer provides mechanical strength, clarity, dimensional stability, and printability. EVOH provides the principal oxygen-barrier function, while the PE-based inner layer seals to a compatible PE sealing surface.
The standard product on this page is positioned as a high-barrier lock-seal film, not an easy-peel grade. It is primarily intended for compatible PET/PE trays, PET/EVOH/PE trays, and other trays whose sealing flange presents a suitable PE-based surface.
HSQY supplies nominal thicknesses from 0.052mm to 0.09mm, roll widths from 150mm to 900mm, and standard 500m rolls with custom conversion available. The final oxygen barrier, moisture barrier, seal strength, shelf life, and MAP performance must be specified and tested under agreed conditions.

Why Use EVOH in Tray Lidding Film?
Low oxygen transmission: EVOH can significantly reduce oxygen entry when protected within a correctly designed multilayer structure.
Aroma protection: The barrier layer helps reduce aroma loss and external odor transmission.
MAP gas retention: A high-barrier lid can help maintain the selected package atmosphere when the tray, seal, and package geometry are also suitable.
Product-quality protection: Reduced oxygen exposure may slow oxidation, discoloration, rancidity, and flavor degradation for appropriate foods.
Transparent packaging: Clear PET- and PE-based layers allow product visibility without relying on aluminium foil.
Mechanical performance: PET or BOPET provides stiffness, tensile strength, puncture resistance, and stable web handling.
Custom printing: The outer PET layer can support branding, product information, barcodes, and traceability.
How the PET/EVOH/PE Structure Works
| Layer |
Primary Function |
Purchasing Consideration |
| PET / BOPET Outer Layer |
Provides clarity, stiffness, tensile strength, dimensional stability, puncture resistance, and printability. |
Confirm gauge, haze, gloss, surface treatment, shrinkage, and print requirements. |
| Printing Layer |
Carries branding, product information, barcodes, cooking instructions, and traceability. |
Confirm surface or reverse printing, ink system, colors, print repeat, and eye-mark location. |
| Laminating Adhesive |
Bonds the PET layer to the barrier and sealing structure. |
Confirm cure time, bond strength, migration, odor, and storage requirements. |
| Tie Layers |
Bond EVOH to surrounding polyolefin layers that would not otherwise adhere reliably. |
Confirm delamination resistance and the complete coextruded or laminated structure. |
| EVOH Barrier Layer |
Provides the main oxygen and aroma barrier. |
Barrier performance depends on EVOH grade, thickness, temperature, and relative humidity. |
| PE-Based Sealant Layer |
Provides heat sealing to a compatible PE sealing surface and controls lock-seal performance. |
Must be matched to the tray flange, sealing window, contamination level, and required seal strength. |
EVOH Barrier Performance and Humidity
EVOH is an effective oxygen-barrier material, but its barrier performance is sensitive to moisture. For this reason, EVOH is normally protected between moisture-resistant polymer layers rather than used as an exposed surface.
OTR values should always state the test temperature, relative humidity, specimen thickness, and test standard. A value measured in dry laboratory conditions should not be presented as the guaranteed barrier performance of a moist chilled-food package without relevant testing.

OTR and WVTR: The Two Critical Barrier Values
| Barrier Metric |
What It Measures |
What the Buyer Should Specify |
| OTR |
The amount of oxygen passing through a defined film area over a defined time. |
Maximum value, test standard, temperature, relative humidity, film orientation, and units. |
| WVTR |
The amount of water vapour passing through a defined film area over a defined time. |
Maximum value, test standard, temperature, relative humidity gradient, and units. |
| Whole-Pack Oxygen Ingress |
Oxygen entering through the lid, tray, seal, corners, pinholes, and package leaks. |
Pack size, tray barrier, seal width, leak-test method, storage period, and acceptable residual oxygen. |
| Gas Retention |
The package’s ability to maintain the selected MAP gas composition over time. |
Initial gas mix, headspace, product respiration, storage temperature, target shelf life, and test intervals. |
Do not compare suppliers using an OTR number alone unless the units and test conditions are identical. Barrier values measured at different humidity or temperature conditions may not be directly comparable.
High Barrier Does Not Automatically Mean Long Shelf Life
High-barrier film can support shelf-life objectives, but it does not independently determine the final shelf life. Food microbiology, raw-material quality, hygiene, filling temperature, residual oxygen, gas mix, tray barrier, seal integrity, cold-chain control, preservatives, and package leakage all contribute.
Shelf-life claims should be supported by product-specific storage trials and microbiological, sensory, chemical, color, purge, and package-integrity testing.
MAP Packaging System Requirements
| MAP Component |
Why It Matters |
Validation Requirement |
| Lidding Film |
Controls oxygen ingress, gas loss, puncture resistance, and seal performance. |
OTR, WVTR, thickness, seal strength, and roll quality. |
| Tray |
The tray can be a major route for oxygen transmission if its barrier is too low. |
Tray wall structure, EVOH thickness, flange composition, dimensions, and OTR. |
| Seal |
A high-barrier lid cannot compensate for a weak, contaminated, or incomplete seal. |
Seal width, temperature, pressure, dwell time, contamination tolerance, and leak testing. |
| Gas Mixture |
CO₂, N₂, and O₂ levels are selected according to product type and microbiological requirements. |
Initial gas concentration, residual oxygen, headspace ratio, and gas-analysis schedule. |
| Cold Chain |
Temperature affects microbial growth, product respiration, gas solubility, and barrier behavior. |
Filling, transport, retail, and consumer storage temperatures. |
Tray Material Compatibility
| Tray Material |
Compatibility Guidance |
Recommended Approach |
| PET/PE Tray |
Primary application when the tray flange presents a compatible PE sealing surface. |
Confirm PE grade, flange geometry, and seal strength on the actual tray. |
| PET/EVOH/PE Tray |
Suitable for complete high-barrier MAP systems when the outside sealing surface is PE. |
Match tray and lid OTR, verify gas retention, and test the complete package. |
| APET / RPET Tray |
A plain PET flange may not seal correctly to the standard PE sealant. |
Use a PET-compatible or universal sealant grade after testing. |
| CPET Tray |
Standard PET/EVOH/PE lock-seal film should not automatically be treated as ovenable or CPET-compatible. |
Use a dedicated CPET-compatible thermal structure. |
| PP / PP-EVOH-PP Tray |
A PP sealing surface usually requires a PP-compatible sealant. |
Use EVOH/PP or another PP-compatible lidding-film structure. |
| Aluminium or Coated Paperboard |
Requires substrate-specific sealing chemistry. |
Send samples and develop a dedicated sealing grade. |
Lock Seal vs. Easy Peel
| Seal Type |
Opening Behaviour |
Typical Use |
| Lock Seal / Weld Seal |
Strong permanent bond; opening may tear the film or distort the tray flange. |
MAP meat, poultry, seafood, cheese, liquid-containing foods, and tamper-evident packs. |
| Hard Peel |
Peelable seal with relatively high opening force. |
Products needing distribution security with eventual manual opening. |
| Easy Peel |
Controlled consumer opening with reduced shredding or residue. |
Retail convenience foods; requires a separate easy-peel sealant grade. |
The standard product on this page is listed as non-easy-peel. Do not use “clean peel” or “consumer easy opening” claims unless a separate peelable grade is supplied and tested.
Applications
Fresh red meat and processed meat MAP packs
Poultry and seafood trays
Cheese and dairy products

Frequently Asked Questions
What is PET/EVOH/PE high-barrier lidding film?
It is a multilayer tray-sealing film that combines PET or BOPET for strength, EVOH for oxygen barrier, and a PE-based layer for sealing to a compatible PE sealing surface.
What does EVOH do in lidding film?
EVOH reduces oxygen and aroma transmission. Its performance depends on grade, thickness, temperature, humidity, and protection by the surrounding layers.
Is EVOH also a moisture barrier?
EVOH is primarily selected for oxygen and aroma barrier. Its oxygen-barrier performance can decline at high humidity, so moisture-resistant layers are used to protect it.
What OTR should I specify?
The correct OTR depends on the food, tray, gas mixture, shelf life, and storage conditions. Always specify units, temperature, relative humidity, and test standard.
What is the difference between OTR and WVTR?
OTR measures oxygen transmission. WVTR measures water-vapour transmission. Both may be relevant, but they protect against different package risks.
Can high-barrier film guarantee a longer shelf life?
No single film can guarantee shelf life. Tray barrier, seal integrity, hygiene, gas mix, product microbiology, residual oxygen, and cold-chain control must also be validated.
Which trays can this film seal?
The standard PE sealant is mainly intended for PET/PE, PET/EVOH/PE, and other trays with a compatible PE sealing surface.
Can it seal plain APET, CPET, or PP trays?
Not automatically. Plain PET, CPET, and PP surfaces may require different sealing layers. Send the actual tray for compatibility testing.
Is the standard grade easy peel?
No. The current standard grade is a lock-seal film. Easy-peel performance requires a separately formulated peelable sealing layer.
Is anti-fog available?
The current standard grade is listed without anti-fog. An anti-fog version can be evaluated according to product moisture, storage temperature, and shelf life.
Is the standard grade freezer, microwave, or oven safe?
No. The current page lists the standard grade as non-freezer, non-microwave, and non-ovenable. A special grade requires separate validation.
Can the film be custom printed?
Yes. Printing can include logos, ingredients, product information, barcodes, QR codes, date-code areas, and transparent windows.
What sizes are available?
The current page lists 0.052–0.09mm thickness, 150–900mm width, and 500m standard roll length, with custom roll conversion available.
What is the minimum order quantity?
The current stated MOQ is 1000kg. Trial quantities depend on barrier structure, width, printing, stock, and conversion requirements.
Can I request samples and MAP line trials?
Yes, subject to material availability and specification. Provide the tray, food application, gas mix, target barrier, line details, and required roll configuration.
