11-Layer High Barrier Medical Packaging Film
HSQY 11-layer PA/PP/EVOH/PE high barrier medical packaging film is a multilayer co-extruded flexible film designed for medical device, medical textile and other sensitive healthcare packaging applications requiring oxygen barrier, puncture resistance, mechanical durability and heat-sealing performance.
The 11-layer structure is PA/TIE/PP/TIE/PA/EVOH/PA/TIE/PE/PE/PE. EVOH provides the primary high oxygen-barrier function, PA contributes toughness and puncture resistance, while PE and PP layers support flexibility, moisture protection, sealing and processing performance.
Available film thicknesses range from 0.03mm to 0.45mm, with widths up to 4000mm. Clear and printable configurations are available for suitable packaging requirements.
An easy-peel configuration is available for suitable medical packaging applications. Final peel behavior depends on the sealing layer, mating substrate, seal temperature, pressure and dwell time, so the complete package should be tested under the customer's actual packaging conditions.

How the 11-Layer Film Structure Works
Multilayer co-extrusion allows different polymers to perform different functions within one flexible film. The HSQY 11-layer structure combines PA, PP, EVOH, PE and tie layers.
| Material |
Main Role in the Multilayer Structure |
| PA / Polyamide / Nylon |
Provides toughness, puncture resistance, flex resistance and mechanical protection. |
| EVOH |
Provides the principal high oxygen- and gas-barrier function. |
| PP / Polypropylene |
Contributes mechanical, chemical and thermal performance according to the final structure. |
| PE / Polyethylene |
Supports flexibility, moisture resistance and sealing performance. |
| TIE Layers |
Bond otherwise incompatible polymer layers together within the co-extruded structure. |
Why Use EVOH in Medical Packaging Film?
EVOH is incorporated into multilayer packaging primarily to reduce oxygen and gas transmission. This can be important when a medical device, medical textile or packaged component is sensitive to oxidation or other environmental exposure.
EVOH is not used alone in this HSQY structure. It is protected by surrounding PA, PP and PE layers, allowing the complete 11-layer construction to balance barrier performance with flexibility, puncture resistance, sealability and converting performance.
Key Features of High Barrier Medical Packaging Film
1. High Oxygen Barrier
The EVOH layer provides strong resistance to oxygen and gas transmission, supporting packaging applications where barrier performance is a critical selection factor.
2. Puncture Resistance
Multiple PA layers help protect the package against puncture and mechanical stress caused by rigid or irregularly shaped medical products during handling and distribution.
3. Multilayer Protection
The 11-layer construction allows barrier, mechanical, sealing and moisture-protection functions to be distributed across specialized polymer layers.
4. Heat-Sealing Capability
The film is designed for heat-sealing applications. Final sealing temperature, pressure and dwell time should be established using the exact mating substrate and packaging machine.
5. Easy-Peel Option
The product is marketed for easy-peel medical packaging applications. Peel performance should be validated against the actual lidding or mating material to achieve the required balance between package integrity and controlled opening.
6. Clear Product Visibility
Clear film allows visual inspection of the packaged product where visibility is required by the packaging design.
7. Printable Configuration
Printable film options can support identification, instructions, branding and other package information according to the selected printing system.
8. Wide Customization Range
Thicknesses from 30μm to 450μm and widths up to 4000mm provide flexibility for different packaging machines and package dimensions.
Easy-Peel Medical Packaging Film
In medical packaging, easy peel should not mean weak sealing. A peelable package needs sufficient seal integrity during handling, sterilization, distribution and storage while allowing controlled opening at the point of use.
Peel characteristics depend on the relationship between the film sealing layer and the opposite substrate. Buyers should therefore provide the exact medical paper, Tyvek-type substrate, film, tray or other sealing surface used in the finished package.
Seal Strength: Establish sufficient package integrity for the intended handling and distribution conditions.
Peel Force: Determine the required opening force according to package size and intended use.
Clean Peel: Evaluate the seal interface for fiber tear, delamination, stringing or other undesirable opening behavior.
Seal Window: Confirm stable sealing performance across the actual temperature, pressure and dwell-time range used on the packaging line.
Medical Device and Medical Textile Packaging Applications
High-barrier multilayer film can be evaluated for medical packaging projects where a combination of gas barrier, physical protection, clarity and sealability is required.
Medical Devices: Flexible packaging for suitable devices requiring transparent barrier protection and mechanical durability.
Medical Textiles: Packaging for suitable textile-based healthcare products where barrier and package integrity requirements have been established.
Diagnostic Components: High-barrier packaging may be evaluated for sensitive components requiring protection against oxygen or environmental exposure.
Thermoformed Medical Packs: Multilayer film can be evaluated for forming applications according to required forming depth and the exact film grade.
Peelable Medical Packages: Suitable structures can be evaluated where controlled peel opening is required with a compatible sealing substrate.

Sterilization Compatibility
Sterilization suitability depends on the selected film grade and the exact processing method. The required sterilization method, temperature, dose and processing cycle should be provided for compatibility evaluation.
Medical packaging materials can respond differently to ethylene oxide, radiation, steam and other sterilization processes. The selected film and complete package should therefore be evaluated using the exact sterilization process intended for the finished medical product.
Sterilization Method: Provide EO, gamma, e-beam, steam or other required process when requesting product evaluation.
Process Conditions: Provide temperature, exposure time, radiation dose or other applicable cycle parameters.
Seal Integrity: Evaluate package seals before and after sterilization.
Barrier Retention: Confirm that required barrier properties remain acceptable following the intended sterilization process.
Mechanical Integrity: Evaluate puncture, flexing, delamination and other package risks after processing.
Medical Packaging Validation and ISO 11607
For terminally sterilized medical devices, the flexible film is only one component of the finished packaging system. Material selection, forming, sealing, sterilization, distribution and storage should be evaluated together.
ISO 11607 addresses materials, sterile barrier systems and packaging systems used for terminally sterilized medical devices, as well as validation of forming, sealing and assembly processes.
Material Qualification: Confirm that the selected film is appropriate for the intended device, packaging configuration and sterilization method.
Seal Process Development: Establish suitable temperature, pressure and dwell-time parameters.
Package Integrity: Assess seals and package integrity before and after sterilization.
Distribution Testing: Evaluate the finished packaging system after simulated transport and handling where applicable.
Aging: Confirm packaging performance through the intended shelf-life program.

Quality and Certification Documentation
Medical packaging projects may require product specifications, barrier test data, mechanical-property reports, sterilization compatibility information, quality-system documentation and other market-specific records.
Request documentation for the exact HSQY film grade being evaluated. General company certificates should not automatically be interpreted as medical packaging validation or certification of a specific finished sterile barrier system.
