Medical device packaging pouch

plasticpaperTyvek®

Summary
Transparent paper-plastic pouches for medical device packaging that combine a permeable sterilization paper side with a PET-based transparent composite film. Designed for compatibility with packaging equipment and validated sterilization methods, they provide a reliable microbial barrier while allowing visual inspection of contents.

Structural composition
Manufactured from permeable sterilization paper (domestic or imported) laminated to a PET-based transparent composite film. The film is multi-layered, typically with polypropylene as the inner layer and polyester (PET) as the outer layer to ensure clarity and strength.

Sterilization & sealing
Suitable for sterilization by steam under pressure and ethylene oxide (EO). The transparent composite film is heat-sealable; recommended heat-sealing temperature range: 150°C–180°C. Pouches enable final sterilization of packaged medical items without compromising material integrity.

Product features

• Sterile: supports final sterilization of medical packaging and devices by validated methods while maintaining material properties.
• Shelf life: stable barrier performance over the product lifecycle to support long-term storage of sterile items.
• Environmental barrier: effective isolation against moisture, air, bacteria, oxygen and light.
• Physical protection: protects against impact and abrasion; explosion-proof edge-sealing process reduces risk of bursting.
• Visual inspection: transparent film side allows immediate identification of contents without opening the package.
• Printed chemical indicators: pouches can include printed indicators for steam and EO sterilization to verify sterilization (color-change indication).

Materials & performance
The paper side is permeable to sterilants while the film side is liquid- and gas-impermeable to maintain a microbial barrier. This combination delivers strong bacterial barrier performance, high water resistance and sufficient breathability for effective sterilization without creating wet packages. The paper maintains tensile strength and tear resistance during high-temperature moist-heat sterilization.

Applications & benefits
Used to package and seal medical instruments and devices for final sterilization and sterile storage. Helps reduce repeat sterilization, lowers consumable waste and enables ready clinical use. Suitable across a wide range of surgical and clinical procedures and for varied sterile pack configurations.
