POLYPROPYLENE LAMINATED SHEET OR FILM AND ITS MANUFACTURE

摘要

PURPOSE:To provide a polypropylene laminated sheet with an excellent moldability which is used to provide a packaging material with excellent surface gloss and transparency by applying a resin composition containing polypropylene with a syndiotactic structure. CONSTITUTION:A polypropylene laminated sheet or film which has excellent surface gloss and transparency and favorable moldability can be obtained by laminate-forming a polypropylene resin composition consisting of syndiotactic polypropylene, or syndiotactic polypropylene and isotactic polypropylene. The polypropylene resin composition with a syndiotactic structure is a polypropylene resin composition consisting of 9-95 pts.wt. of syndiotactic polypropylene and 95-5 pts.wt. of isotactic polypropylene.
