What Is PA/PE/EVOH High Barrier Film?

PA/PE/EVOH film is a multilayer coextruded or composite flexible packaging material that combines several polymers so that each layer performs a different function. Instead of relying on a single polymer for strength, sealing and barrier performance, the structure combines complementary materials into one film.

EVOH is particularly effective as an oxygen and gas barrier but its barrier performance can be affected by humidity. In a multilayer structure, PE and other protective layers help isolate the EVOH layer from direct environmental exposure while also contributing heat-sealing and water-vapor resistance.

This combination makes multilayer PA/EVOH/PE structures useful where buyers require transparency, mechanical toughness, puncture resistance and controlled gas transmission in one flexible packaging material.

PA/PE/EVOH Composite Film Specifications

The following specifications are based on the current HSQY product information. Final layer structure and technical performance should be confirmed according to the selected grade and application.

How the PA/PE/EVOH Multilayer Structure Works

PA Layer – Mechanical Strength and Puncture Resistance

Polyamide, commonly called PA or nylon, contributes toughness, mechanical strength, abrasion resistance and puncture resistance. These properties are valuable when packaged components contain corners, leads or irregular shapes that may place mechanical stress on the film.

EVOH Layer – Oxygen and Gas Barrier

EVOH, or ethylene vinyl alcohol, provides the primary high oxygen and gas barrier function in the multilayer film. It is normally protected within the multilayer structure rather than being directly exposed as an unsupported single layer.

PE Layer – Heat Sealing and Water-Vapor Resistance

Polyethylene contributes flexibility, heat-sealing functionality and resistance to water-vapor transmission. The exact sealing window, seal strength and moisture-barrier performance depend on the selected film formulation, gauge and converting conditions.

Tie Layers – Multilayer Adhesion

Tie or adhesive-resin layers bond polymers such as PA, EVOH, PP and PE together because these materials do not naturally adhere equally well to one another. The result is an integrated multilayer film structure.

Key Features of PA/PE/EVOH High Barrier Film

High Oxygen Barrier: The internal EVOH layer provides strong resistance to oxygen and other gas transmission when incorporated into a suitable multilayer structure.

Moisture Resistance: PE layers contribute water-vapor resistance and help protect the EVOH barrier layer from direct humidity exposure.

Puncture Resistance: PA improves toughness and resistance to puncture, helping maintain package integrity around components with edges or irregular shapes.

High Transparency: Clear multilayer construction allows packaged products or components to remain visible for inspection and identification where transparent packaging is preferred.

Heat-Sealing Capability: PE sealant layers support heat-sealed packaging. The required seal temperature, dwell time and pressure should be confirmed according to the selected film and packaging equipment.

Wide Thickness Range: Thicknesses from 0.045mm to 0.35mm allow the material to be considered for different packaging formats and mechanical-performance requirements.

Wide Roll Width: Widths from 160mm to 2600mm help support different converting and packaging equipment configurations.

Custom Multilayer Structure: Film structure and specification can be discussed according to barrier, sealing, mechanical and converting requirements.

Applications of PA/PE/EVOH Film in Electronic Packaging

Electronic Components: Suitable for selected electronic components that require transparent flexible packaging with oxygen, moisture and mechanical-barrier properties.

IC-Related Components: Can be evaluated for components and assemblies where environmental barrier protection is needed, provided any required ESD or static-control specification is separately confirmed.

LED Light Strips and Lighting Components: Transparent film allows product visibility while helping protect products during storage, handling and transportation.

Automotive Electronic Parts: PA-based multilayer films provide useful toughness for selected automotive components and accessories where flexible barrier packaging is required.

Industrial Components: The material can also be considered for non-food industrial goods requiring transparent, puncture-resistant and high-barrier flexible packaging.

       Discuss Your Electronic Packaging Application    

Is PA/PE/EVOH Film ESD or Anti-Static?

Standard PA/PE/EVOH high barrier film should not automatically be considered an ESD shielding bag, anti-static film or static-dissipative packaging unless the selected product has specifically been designed and tested for those electrical properties.

Some semiconductor, PCB and moisture-sensitive-device packaging applications require specifications such as surface resistance, static dissipation, electrostatic shielding, MVTR and compliance with specific ESD or dry-packaging standards. If your application has these requirements, provide the exact electrical and moisture-barrier specification to HSQY before ordering.

For applications that primarily require transparency, oxygen barrier, water-vapor resistance, puncture resistance and heat sealing without a specified ESD shielding requirement, PA/PE/EVOH multilayer film may provide an appropriate packaging solution after technical evaluation.

How to Choose PA/PE/EVOH Film for Electronic Packaging

1. Define the Required Barrier Performance

Determine whether your project has a specified oxygen transmission rate, water-vapor transmission rate or storage-life requirement. If OTR or WVTR values are stated in your technical specification, provide the target value together with the required test method.

2. Confirm Whether ESD Protection Is Required

If the packed electronic component is static sensitive, specify whether you need anti-static, static-dissipative or electrostatic-shielding performance. These are different electrical functions and should not be assumed from barrier-film composition alone.

3. Select Film Thickness

HSQY currently lists a thickness range of 0.045mm to 0.35mm. Thicker film may provide additional mechanical robustness, while the correct gauge should be determined by package format, component shape, sealing process and performance requirements.

4. Confirm Roll Width and Packaging Equipment

Provide the required roll width, roll diameter, core size and equipment information where applicable. HSQY currently lists widths from 160mm to 2600mm.

5. Confirm Heat-Sealing Requirements

Tell HSQY how the film will be sealed, including packaging-machine type, sealing surface, temperature range and required seal strength when available. This helps determine whether the selected sealant structure is suitable.

6. Evaluate Puncture and Mechanical Requirements

Components with sharp corners, terminals, leads or irregular geometry may require greater puncture resistance. Send photographs, drawings or samples where possible so the packaging requirement can be evaluated more accurately.

Technical Data Buyers Should Confirm

For engineering and electronics packaging projects, product selection should ideally be based on measurable performance data rather than material name alone. Ask for the relevant technical data for the specific film grade being quoted.

• OTR – Oxygen Transmission Rate

• WVTR / MVTR – Water Vapor or Moisture Vapor Transmission Rate

FAQ About PA/PE/EVOH High Barrier Film

What is PA/PE/EVOH composite film?

PA/PE/EVOH film is a multilayer flexible packaging material combining polyamide, polyethylene and EVOH barrier resin. PA contributes mechanical strength, EVOH provides oxygen barrier performance and PE contributes sealing and water-vapor resistance.

Why is EVOH used in high barrier film?

EVOH has very low oxygen permeability compared with many common packaging polymers. In multilayer packaging, it is normally protected between other polymers because humidity can affect its oxygen-barrier performance.

Is PA/PE/EVOH film suitable for electronic components?

It can be suitable for selected electronic and industrial components requiring transparent high-barrier and puncture-resistant flexible packaging. The correct film should be selected according to the component, required OTR or WVTR, sealing method and any electrical-protection requirements.

Is this film an ESD moisture barrier bag?

Not automatically. Standard PA/PE/EVOH composition does not by itself prove anti-static, static-dissipative or ESD shielding performance. If your electronic device requires ESD protection, provide the required surface resistance, shielding or applicable ESD standard before ordering.

Does PA/PE/EVOH film provide moisture protection?

PE and other outer layers can contribute water-vapor resistance, while EVOH primarily provides oxygen and gas barrier performance. For moisture-sensitive electronics, the required WVTR or MVTR should be specified and verified for the actual film grade.
