PRODUCTION OF BASE FILM FOR ELECTROCONDUCTIVE ADHESIVE TAPE

摘要

PURPOSE:To provide a method for producing a base film which has electrical conductivity and is suitably used for an electroconductive adhesive tape excellent in affinity for adhesive material. CONSTITUTION:A base film for an electroconductive adhesive tape is produced by performing corona discharge treatment on an electroconductive layer consisting of thermoplastic resin (especially polyolefine-based resin) containing an electroconductive filler especially carbon black and on the surface of the nonelectroconductive layer of a multilayer film which consists of thermoplastic resin and has the nonelectroconductive layer having a thickness of 30mum or more.
