Sterilization roll for EO (Ethylene Oxide) and Steam sterile use is a specialized packaging material designed to ensure the sterility, safety, and integrity of medical devices, instruments, and other sterile products throughout their storage and transportation. Widely used in hospitals, clinics, pharmaceutical factories, and medical laboratories, this high-performance roll plays a critical role in infection control and patient safety by creating a barrier that prevents contamination before use.

Unlike ordinary packaging materials, it is engineered to withstand the harsh conditions of both EO gas sterilization and high-pressure steam sterilization, two of the most common and effective sterilization methods in the medical and healthcare industry.

The key characteristic of this sterilization roll is its dual compatibility with EO and steam sterilization, which is achieved through its carefully selected material composition and structural design. The base material of the roll is typically a multi-layer composite film, combining medical-grade non-woven fabric, polyethylene (PE), and polyester (PET) layers. Each layer serves a specific purpose: the non-woven fabric provides breathability, allowing the sterilizing agent to penetrate evenly; the PE layer acts as a moisture barrier; and the PET layer enhances tensile strength and puncture resistance.
