Key Guidelines for Using Sterilization Paper-Plastic Bags Correctly

February 09, 2026

Proper use of sterilization paper-plastic bags is critical to maintaining instrument sterility and preventing cross-contamination. Even high-quality bags can fail if not used according to best practices.

First, never overfill the bag—leave at least 2.5 cm of space at the top to ensure the sterilizing agent can penetrate fully and the bag can be sealed properly. Avoid folding or crumpling the paper side, as this can block the flow of sterilizing agents.

Always seal the bag with a compatible sealer (heat sealer or self-adhesive strip) to create an airtight barrier. Label each bag clearly with the sterilization date, expiration date, and instrument contents for traceability. Store sealed bags in a clean, dry area away from direct sunlight and moisture.
