<P>PROBLEM TO BE SOLVED: To provide an OPP film for fusion-cut sealing which gives a fusion-cut sealing strength of 20N/15 mm or more even under high-speed conditions by taking advantage of excellent characteristics of a propylene series resin. <P>SOLUTION: The OPP film for fusion-cut sealing 1 includes: an intermediate layer 2 formed of propylene homopolymer; and skin layers 3, 4 provided to sandwich the intermediate layer 2, and formed of propylene series random copolymer. The intermediate layer 2 contains 0.005-0.1 pts.wt. of a crystallization nucleating agent with respect to 100 pts.wt. propylene homopolymer. <P>COPYRIGHT: (C)2013,JPO&INPIT |
