PRODUCTION OF GAS BARRIER SHEET AND THERMOFORMED ARTICLE |
摘要 |
PURPOSE:To obtain a low cost gas barrier sheet enhanced in smoothness by laminating a gas barrier multilayered film and a molten polypropylene resin film between a pair of cooling rolls. CONSTITUTION:The molten polypropylene resin film extruded through a T-die is laminated to the polypropylene resin layer of a non-stretched laminated film with a thickness of 10-100mum containing such a structure that a barrier layer is laminated to a polypropylene resin layer through an adhesive layer between a pair of cooling metal rolls arranged in a linear or surface contact state before the molten polypropoylene resin film is solidified. The gas barrier sheet thus obtained has a thickness of 0.2-1.6mm and is thermoformed to obtain a molded product. |
