Nylon is not recommended for ethylene oxide (EO) sterilization due to its moisture absorption properties, which can interfere with the sterilization process. EO sterilization requires the materials to maintain a specific moisture level in order to effectively penetrate and disinfect the items. Nylon can absorb water, leading to inconsistent sterilization outcomes.

In contrast, materials like Tyvek, paper, and polyethylene are designed for compatibility with EO sterilization. Tyvek is a breathable material that allows gas to permeate while providing a barrier to microorganisms. Paper is also breathable and has been widely used for many years in sterilization processes. Polyethylene, while not the most common choice for EO, is generally considered more acceptable than nylon because it does not absorb moisture in the same way and has adequate barrier properties when appropriately used.
