EVOH High Barrier Sterilization bag film

Coextruded EVOH High Barrier Sterilization bag film

Sterilization bag film is typically made from a combination of materials to provide optimal barrier properties. One common composition is a multilayer film consisting of polyethylene (PE) and ethylene-vinyl alcohol copolymer (EVOH) layers. The PE layers provide flexibility and durability, while the EVOH layer contributes high barrier properties to prevent the ingress of microorganisms and maintain the sterility of the contents.

The film is often transparent or translucent, allowing for easy visual inspection of the packaged items. It may also incorporate indicators that change color or display other visible cues to indicate that proper sterilization has occurred.

The sealing strength of sterilization bag film is crucial to ensure the integrity of the packaging during sterilization processes such as steam autoclaving or ethylene oxide (ETO) sterilization. The film should have excellent heat-sealing properties to create a strong and airtight seal, preventing the entry of contaminants after sterilization.
