摘要
A composite plastic sheet has a solid, hot calendered carrier layer of essentially recycled material. The surface is treated to improve the adhesion of a facing layer of film, metal or textile fabric which is applied with an adhesive under pressure. The surface treatment can be carried out by the last roll pair, or by machining, electronic, chemical or physical operations such as corona discharge or oxidn. with an open flame. USE/ADVANTAGE - Provides improved adhesion of facing material on laminated plastic sheet with a core of recycled polymer
