PROBLEM TO BE SOLVED: To provide a paper for sterilized bag being equipped with an excellent heat-sealability and peelability, which can be used for large sized bags, together with a favorable air permeability and water resistance by a method wherein on one surface of a base paper for which aluminate is added to pulp fiber, a coating layer containing at least an acryl based copolymer, is applied. SOLUTION: On one surface of a base paper for which 0.1-2.0 pts.wt. of aluminate is added based on 100 pts.wt. of pulp fiber, a coating layer containing at least an acryl based copolymer, is applied for this paper for sterilized bag. The application of 0.2-2.5g/m<2> of a copolymer comprising styrene and acrylic ester or methacrylic ester and acrylic amide, as the acryl based copolymer, is desirable. In addition, in order to obtain an especially favorable sizing degree as the water resistance, the mixing of alkylketone dimer with a blending ratio of 2-40wt.% as a neutral sizing agent for the acryl based copolymer, is desirable. |
