BUFFER SHEET AND MANUFACTURE THEREOF

摘要

PURPOSE:To provide a buffer sheet which can be separated into a plastic part and opaque part and reused as reclaimed plastic at the time of abandonment, by laminating a plastic embossed film and an opaque film which is stuck together peelably with a peeling film. CONSTITUTION:A buffer sheet 4 sticks an embossed film 22 and base part 1 together by performing heat fusing at a temperature of at least the softening point of a peeling film 12 and not exceeding 210 deg.C while pressure-contacting the peeling film 12 side of the base part 1 with the embossed film 22. That is, the buffer sheet 4 is manufactured by a process wherein an embossment 21 is formed on the film 22 by winding a film made of plastic formed by an inflation method or a T-die method at a temperature of at least the melting point not exceeding 280 deg.C around an embossing roll having a large number of recessed parts in the circumferential surface, at the same time the base part 1 which is preheated at the softening point of the film 12 or higher is wound around the upper part of the film 22 so that the film 12 side and film 22 come into contact with each other and performs the heat fusion of the base part 1 and film 22 on the embossing roll while pressure-contacting them.
