High Barrier PET/PE Lamination Film for Food Packaging

High Barrier PET/PE Lamination Film for Food Packaging

HSQY high barrier PET/PE lamination film combines a PET outer layer for mechanical strength, dimensional stability and printability with a PE sealing layer for flexibility and heat sealing. Barrier options listed for the current product range include EVOH and PVDC technologies for food packaging applications requiring improved protection against oxygen, moisture and aroma transmission.

The current range is available in approximately 45-350μm thicknesses and 160-2600mm widths, with clear film and 1-13 color printing options. It can be evaluated for vacuum packaging, modified atmosphere packaging, meat, fish, seafood, dairy products, coffee, snacks and other oxygen- or moisture-sensitive foods.

High-barrier performance depends on the exact laminate structure, barrier layer, total thickness, sealing layer and test conditions. Final OTR, WVTR, seal strength, thermal-processing compatibility and shelf-life performance should therefore be confirmed for the approved film specification and actual packed food.

High Barrier PET/PE Lamination Film Specifications

Technical Note: The current product information does not publish grade-specific OTR, WVTR, seal initiation temperature, seal strength, laminate bond strength, roll core diameter, maximum roll OD or thermal-processing limits. These values should be confirmed for the exact construction used in the final package.

PET/PE Laminate Structure

PET and PE perform different functions within a flexible laminate. Combining them allows the package designer to balance stiffness, printability, mechanical strength, sealing and barrier performance.

EVOH High-Barrier Option

EVOH is widely used as an oxygen-barrier material in multilayer food packaging structures. When protected within the laminate, it can significantly reduce oxygen transmission compared with a standard PET/PE structure.

EVOH barrier performance is affected by humidity, layer thickness and the complete laminate design. For this reason, a product described only as “PET/PE/EVOH” does not provide enough information to predict package shelf life without the actual OTR specification and test conditions.

PVDC High-Barrier Option

PVDC is also referenced in the current HSQY product specification as a high-barrier technology. It can provide strong oxygen, aroma and moisture barrier performance when used in an appropriate packaging structure.

The exact PVDC configuration and coating or laminate construction are not published on the current page. Buyers requiring a PVDC structure should request the corresponding layer specification, coating information where applicable, OTR, WVTR and food-contact documentation.

Standard PET/PE vs. High-Barrier PET/PE Film

Understanding OTR for High-Barrier Food Packaging

OTR, or oxygen transmission rate, is one of the most important specifications when selecting a high-barrier food packaging film. It indicates how much oxygen can pass through the material under defined test conditions.

A lower OTR generally provides stronger oxygen protection, but an OTR value is meaningful only when the test temperature, relative humidity, material thickness and test standard are also stated.

The current HSQY page does not publish a single OTR value. Buyers should provide their target OTR or packaged-food shelf-life requirement so the appropriate barrier structure can be evaluated.

Understanding WVTR for Moisture Protection

WVTR describes the rate at which water vapor passes through the film under defined conditions. It can be important for foods where moisture gain or moisture loss affects texture, quality or shelf life.

Coffee, dry foods, bakery products, dairy products and other moisture-sensitive foods may require different moisture-barrier targets. The complete package should therefore be selected according to the actual product rather than from a generic “high barrier” description.

High Barrier Film for Modified Atmosphere Packaging

Modified atmosphere packaging replaces or modifies the gas composition inside a package to support product quality and shelf life.

For MAP applications, the film needs to work with the complete package system. Film barrier, sealing layer, tray or pouch structure, gas mixture, package headspace, storage temperature and seal integrity all influence gas retention.

Buyers should provide the packed food, required gas mixture and target shelf life when requesting a high-barrier PET/PE structure for MAP.

High Barrier Film for Vacuum Packaging

Vacuum packaging removes air from the package before sealing and can be used for meat, seafood, cheese and other products where reduced oxygen exposure is desired.

Vacuum-film selection should consider puncture resistance, seal strength, flex resistance, package shape and oxygen barrier. Products with sharp bones, shells or edges may require different mechanical properties from soft boneless foods.

PET/PE Barrier Film for Meat Packaging

Fresh and processed meat can require protection against oxygen transmission, moisture loss and package leakage while also demanding strong seals and resistance to handling stresses.

When selecting film for meat packaging, provide the meat type, bone-in or boneless condition, vacuum or MAP process, storage temperature and target shelf life.

High Barrier Film for Fish & Seafood

Fish and seafood are included among the typical applications for high-barrier flexible packaging. The original HSQY content also includes a salmon-packaging application image.

Seafood packaging requirements can differ significantly between fresh chilled salmon, frozen fish, shellfish and processed seafood. Film structure should therefore be matched to the actual product, package format and temperature conditions.

High Barrier Film for Cheese & Dairy

Cheese and dairy products may require controlled oxygen and moisture transmission together with reliable sealing and resistance to oils and fats from the packed product.

Different cheeses also have different respiration and gas requirements, so the lowest possible gas transmission is not automatically correct for every dairy application. Buyers should provide the exact product and shelf-life target.

High Barrier Film for Coffee, Tea & Snacks

Coffee, tea, snacks and dry foods can benefit from packaging that limits oxygen, moisture and aroma transfer.

For these applications, buyers should specify whether the final package is a pouch, sachet, flow-wrap or another format and whether light barrier, metallization, matte appearance or special valve compatibility is required.

1-13 Color Printing for Flexible Packaging

The current HSQY specification lists printing from 1 to 13 colors. Printed laminate can combine barrier protection with branding, product information and retail presentation.

For printed projects, provide artwork, printing method, number of colors, required surface finish and any heat- or process-resistance requirements. Printing compatibility should be confirmed for the final laminate structure.

Sealability & Packaging-Line Performance

PE is used as the sealing component in many PET/PE laminate constructions. Actual seal initiation temperature, sealing window and seal strength depend on the selected PE grade and packaging process.

Packaging-line performance is also influenced by film coefficient of friction, stiffness, curl, roll quality and tension control. Buyers using automated form-fill-seal or pouch equipment should provide machine information when possible.

Puncture & Mechanical Protection

The original HSQY content lists strength and puncture resistance among the film's benefits. PET can contribute tensile strength and dimensional stability to the laminate, while the complete structure determines final toughness and flex resistance.

The current page does not publish tensile, elongation, puncture or dart-impact values. Buyers with defined mechanical requirements should request test data for the exact laminate and total thickness.

Aroma & Flavor Protection

Barrier structures can help reduce the transfer of oxygen, aroma and volatile compounds through flexible packaging. This is relevant for foods such as coffee, cheese, seafood and other products where flavor retention is an important part of shelf-life performance.

Actual aroma protection depends on the complete laminate rather than the PET/PE name alone, so the final structure should be selected according to the packed product.

Retort, Boilable & Thermal Processing Requirements

The original HSQY application list references retort and boilable food pouches. These applications should not be assumed for every PET/PE high-barrier laminate.

Retort, pasteurization, hot-fill and boilable processes expose packaging to substantially different temperature and pressure conditions. Projects requiring thermal processing should specify the process temperature, time, pressure and food type so a separately qualified structure can be confirmed.
