What Is 11-Layer High Barrier Co-extrusion Film?

An 11-layer high barrier film is a co-extruded flexible packaging material in which multiple functional polymer layers are combined during production. Each layer performs a specific role such as oxygen barrier, puncture resistance, moisture resistance, heat sealing, mechanical support or layer adhesion.

This multilayer approach allows packaging designers to achieve performance that would be difficult to obtain from a single polymer. The final structure can be optimized according to food type, shelf-life target, packaging process, thermoforming depth, sealing requirements and storage conditions.

High barrier co-extruded films are commonly used as thermoforming bottom webs, vacuum packaging films and flexible packaging structures for meat, seafood, cheese, sausages, ready meals and other oxygen-sensitive products.

PA/PP/EVOH/PE High Barrier Film Specifications

The following specifications are based on the current HSQY product information. Final structure and performance should be confirmed according to the selected film grade and packaging process.

How the PA/PP/EVOH/PE Multilayer Structure Works

PA Layer – Puncture Resistance and Mechanical Strength

Polyamide, or PA, provides mechanical toughness, puncture resistance and strength. These properties are especially important when packaging bone-in meat, seafood shells, cheese blocks and products with sharp or irregular edges.

EVOH Layer – High Oxygen Barrier

EVOH provides the principal oxygen and gas barrier function. Lower oxygen transmission can help reduce oxidation, aroma loss and quality deterioration when the complete package and storage conditions are correctly designed.

Because EVOH barrier performance can be influenced by moisture, it is normally protected within a multilayer structure rather than used as an exposed standalone film.

PP Layer – Heat Resistance and Sealing Options

PP-based layers can be incorporated when additional thermal resistance, stiffness or PP-compatible sealing performance is required. The appropriate PP formulation depends on the target sealing and thermal-processing conditions.

PE Layer – Flexibility, Sealing and Moisture Resistance

PE contributes flexibility, sealability and water-vapor resistance. PE-based sealing structures are widely used for vacuum and thermoforming packaging where reliable heat seals and package flexibility are required.

Tie Layers – Multilayer Adhesion

Tie layers bond incompatible polymers together during co-extrusion, helping create a stable integrated structure and reducing the risk of interlayer separation.

Key Features of 11-Layer High Barrier Film

High Oxygen Barrier: EVOH provides strong oxygen and gas barrier performance for foods requiring controlled exposure to oxygen.

Strong Puncture Resistance: PA helps the film resist puncture and mechanical damage during forming, vacuum packaging, transportation and handling.

Thermoforming Performance: Suitable structures can be formed into flexible cavities for thermoforming bottom-web packaging systems.

Reliable Heat Sealing: PP- or PE-based sealing layers can be selected according to sealing temperature, package structure and equipment configuration.

Vacuum Packaging Compatibility: Flexible high barrier construction can be used in vacuum packs where low oxygen transmission and package integrity are important.

Low-Temperature Options: Suitable structures can be evaluated for chilled and frozen food applications where film flexibility and resistance to cracking must be maintained at low temperatures.

High-Temperature Options: Structures intended for pasteurization, boiling or retort processes must be specifically designed for the required processing temperature, duration and pressure.

High Transparency: Clear film provides visibility of packaged products and supports attractive retail presentation.

Custom Barrier Structure: Layer composition, film thickness and EVOH content can be selected according to required barrier and processing performance.

Applications of PA/PP/EVOH/PE High Barrier Film

Fresh Meat Packaging: Used for beef, pork, poultry and processed meat where puncture resistance, vacuum performance and oxygen barrier are required.

Seafood Packaging: Suitable structures can be used for fresh or frozen fish and seafood where mechanical durability and barrier performance are important.

Cheese and Dairy Packaging: High oxygen barrier and sealing performance can help protect cheese and selected dairy products during refrigerated storage.

Sausage and Processed Food: Flexible multilayer films can be used for vacuum-packed sausages, ham and other processed food products.

Frozen Food Packaging: Low-temperature structures can be selected for products stored or transported under frozen conditions.

Ready Meals: Depending on the complete film structure, suitable high barrier grades can be evaluated for chilled, pasteurized or heat-processed ready-meal packaging.

Retort and Boilable Packaging: Special structures may be available for thermal processing, but the required temperature, time, pressure and food-contact requirements must be confirmed before final film selection.

High Barrier Film for Thermoforming Packaging

In thermoforming packaging, the bottom film is heated and formed into a cavity before the food product is loaded and the package is sealed with a top web. Film performance must therefore balance formability, puncture resistance, barrier properties and seal integrity.

The correct film thickness depends on forming depth, package dimensions, product weight, product shape and the thermoforming machine. A film that is too thin may lose thickness in deep-drawn corners, while unnecessary thickness can increase material cost.

When requesting thermoforming film, provide forming depth, cavity dimensions, machine model and existing film specification where possible so HSQY can evaluate the most appropriate structure.

High Barrier Film for Vacuum Packaging

Vacuum packaging removes a large portion of the air surrounding the food before sealing. A high barrier film then helps limit oxygen entering the package during storage.

PA-containing structures provide useful toughness when the film must closely conform around meat, cheese, seafood or irregular products. Seal strength is also critical because even a very high barrier film cannot maintain package performance if the seal is incomplete or damaged.

Low Temperature vs. High Temperature Barrier Film

How to Choose the Right High Barrier Film

1. Define the Food Product

Start with the packed product: fresh meat, seafood, cheese, sausage, frozen food or ready meal. Different products require different oxygen, moisture and mechanical protection.

2. Confirm the Packaging Process

Confirm whether the film will be used for vacuum packaging, thermoforming, MAP, chilled storage, frozen storage, pasteurization, boiling or retort processing.

3. Define OTR and WVTR Requirements

If your packaging specification defines an Oxygen Transmission Rate (OTR) or Water Vapor Transmission Rate (WVTR), provide the target value and corresponding test conditions. Barrier values are meaningful only when temperature, humidity and test method are specified.

4. Confirm Thermoforming Depth

For bottom-web thermoforming applications, provide cavity length, width, depth and corner radius. Deep forming places greater demands on film thickness distribution and puncture resistance.

5. Confirm Sealing Requirements

Provide the top-film or sealing material, sealing temperature, dwell time and pressure when available. The sealant layer must be compatible with the packaging system.

6. Define the Temperature Range

Do not specify only “low temperature” or “high temperature.” Provide the minimum storage temperature and maximum processing temperature together with exposure time and process type.

7. Confirm Machine Compatibility

Provide your thermoforming or vacuum packaging machine brand, model, roll width, core diameter and maximum roll diameter. This reduces the risk of purchasing a film that meets material requirements but does not run correctly on the production line.

Technical Data Buyers Should Confirm

For professional food packaging projects, film selection should be based on measurable performance data for the actual grade rather than the polymer structure alone.
