A medical sterilization pouch is a single-use pack that enters the sterilizer with the device already sealed inside. It allows steam, ethylene-oxide gas, gamma irradiation, or other sterilants to penetrate and maintains sterility until the pouch is peeled open at the point of care. Conventional sterilization pouches may often present two issues: some materials are designed for only a specific sterilization method, and many paper-based substrates cause lint when opened—both of which can compromise device integrity and patient safety.

DNP’s medical sterilization pouch solves both issues at once with its easy and clean peel design and compatibility with multiple medical sterilization processes.

By applying our proprietary heat-seal coating to the nonwoven substrate, the sterilization pouch peels open smoothly across the entire sealing area, leaving a clean peel surface.

While this coated type offers excellent performance, an uncoated version with easy-peel functionality is also available to meet different needs.

Vertical Integration from printing and coating to bag-making and inspection processes, every stage is performed in-house ensuring a high-quality and stable supply both to Japan and overseas.

For over 30 years, DNP’s medical sterilization pouches have been adopted by medical device manufacturers, pharmaceutical companies and a wide range of other industries—all supported by our rigorous quality management system.

Our medical sterilization pouches are widely adopted for guidewires, catheters and a variety of other medical devices.
