PROBLEM TO BE SOLVED: To obtain a sterilized paper having good air permeability and water resistance, causing no breakage of the sterilized bag made thereof under high- pressure steam sterilization and having a combination of excellent heat sealability and peelability, thus suitable as a sterilized packaging material used in sterilizing medical equipment, especially a sterilized bag of combination type composed of paper and film. SOLUTION: This sterilizing paper is obtained by impregnating a low-air- permeable substrate paper based on pulp fiber and having the air permeability determined in accordance with JISP8117 of <=20 s with 1-10 wt.%, based on the whole weight of the base paper, of an impregnant consisting mainly of an acrylic copolymer with the contact angle (to water) of its emulsion film being >=65 deg.. |
