Medical crepe paper is made from a blend of wood pulp and chemical fibers, featuring a unique wrinkled surface structure. This design enhances the material's mechanical strength while maintaining appropriate permeability, allowing sterilization media (such as high-temperature steam or ethylene oxide) to penetrate the packaging while blocking external microbial contamination. It is primarily used to wrap surgical instruments, dressings, and other items, ensuring a safe and effective sterilization process while maintaining sterility before use. The characteristics of permeability, high-temperature resistance, and tear resistance, making it a key consumable for the sterilization and storage of medical devices.
