How to Choose the Right Sterilization Paper-Plastic Bag for Different Sterilization Methods

February 06, 2026

Not all sterilization paper-plastic bags are the same—selecting the correct type depends heavily on the sterilization method used in your facility. Understanding the compatibility between bags and sterilization techniques is key to ensuring effective sterility and instrument safety.

For steam autoclaving (the most common method), choose bags with a breathable paper layer that can withstand high temperatures (up to 134°C) without tearing or melting. The plastic layer should be heat-resistant to prevent warping during the process.

For ethylene oxide (EO) sterilization, opt for bags with a more porous paper layer to allow EO gas to circulate freely and then dissipate completely. For low-temperature sterilization methods, such as hydrogen peroxide plasma, ensure the bag material is compatible with the sterilizing agent to avoid chemical reactions.
