BIAXIALLY STRETCHED MULTILAYER FILM

摘要

PURPOSE:To sufficiently exhibit antistatic effect by blending a plurality of different compounds and bisamide compound with high crystalline polypropylene and laminating a surface layer constituted of crystalline polypropylene having the specified Vicat softening temperature on the surface of a base material layer constituted of the blended high crystalline polypropylene. CONSTITUTION:Alkyldihydroxyalkylbetai.ne shown in a general formula as mentioned elsewhere is blended at 0.05-0.3wt.% as a compound A with high crystalline polypropylene wherein the relation of melt flow rate and an isotactic pentad fraction satisfies the following formula. 1.00>=P>=0.015log(MFR)+0.955 Further 0.5-1.5wt.% compound B incorporating alkylamine shown in a general formula R1NH2 as a main body and 0.01-0.2wt.% bisamide compound C are blended respectively. A surface layer constituted of crystalline polypropylene as a main component wherein the Vicat softening temperature is in a range within 130-151 deg.C is laminated on the surface of a base material layer incorporating these composition as a main component and thereby a biaxially stretched multilayer film is constituted.
