METHOD FOR MANUFACTURING THERMOPLASTIC RESIN SHEET, POLYPROPYLENE RESIN SHEET AND POLYPROPYLENE RESIN BENT CONTAINER

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a thermoplastic resin sheet more enhanced in glossiness and transparency. SOLUTION: The thermoplastic resin sheet S is brought into close contact with the endless belt 15, which is trained over a plurality of rolls 11-13 and heated by a heating roll part 12 to be allowed to travel and subsequently brought to a planar or linear pressure contact state between the endless belt 15 and a pressure roll 14 before peeled from the endless belt 15. The thermoplasric resin sheet S heated on the side opposite to the endless belt 15 is held in its temperature and/or heated by a heater 18 during traveling. COPYRIGHT: (C)2004,JPO&NCIPI
