SYNTHETIC RESIN MULTILAYER FILM AND BAG USING THIS FILM

摘要

PROBLEM TO BE SOLVED: To provide a multilayer film which includes an antistatic material so that an antistatic component does not bleed out to the inner or outer surfaces of the film, and maintains the antistatic effect for a long time without no adverse effect generated by the transfer of the antistatic component to a bag of the multilayer film, a film container, or an article to be packed, and to provide a bag made of this multilayer film. SOLUTION: The multilayer film 1 is constituted of an intermediate layer 2, an inner layer 3, and an outer layer 4. The intermediate layer 2 shows a resistance value of 108to 1011Ω as a result of adding an antistatic material thereto. In addition, the antistatic material is not added to the outer layer 3 and the inner layer 4 which have each a surface resistance value of not less than 1014Ω. The intermediate layer 2 is not thinner than the outer layer 3 and the inner layer 4. COPYRIGHT: (C)2010,JPO&INPIT
