<P>PROBLEM TO BE SOLVED: To provide a polypropylene-based sheet for a press-through pack having a dividing property similar to that of a vinyl chloride, and also to provide a method for manufacturing the sheet. Ž<P>SOLUTION: The sheet for the press-through pack is a sheet for a press-through pack mainly composed of polypropylene. When the thickness of the sheet is A and the depth of a slit formed for imparting the dividing property is B, the sheet for the press-through pack satisfies an expression (1/2)A≤B≤(4/5)A. The crystallinity degree of the sheet for the press-through pack in the entire sheet thickness direction is 40% or more. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
