摘要：

提供一种具有高耐冲击性的复合树脂膜,以及具有该复合树脂膜层合结构的树脂覆盖金属板,将复合树脂膜覆盖到金属板上并加工成罐体时,可以进行严格的成型加工,以使罐身部位比过去更薄,而且将内容物装入所制得的罐体中并储存一定时间后保持良好的味道,进一步地,即使在装入内容物前后受到外部冲击,皮膜也不会产生裂纹. Providing a composite resin film having high impact resistance, as well as having the resin of the composite resin film laminate structure of the coated metal plate, the composite resin film covered metal sheet into a can body and processed, can be severe forming processing , so that the container body portion is thinner than in the past, and will maintain a good taste of the contents of the tank was placed into the prepared and stored a certain time, and further, even when the load before and after the contents of the external impact, but also coating will not crack. 该复合树脂覆盖金属板,是在金属板上层合这样一种三层树脂膜,其上层以聚酯树脂作为主要成分,中间层为聚酯树脂与聚碳酸酯树脂形成的共混树脂,下层以聚酯树脂作为主要成分. The composite resin covered metal sheet, a metal plate is laminated in such a three-layer resin film, its upper layer to a polyester resin as a main component, the intermediate layer is a blend of a polyester resin and a polycarbonate resin formed of resin, the lower layer to a polyester resin as a main component.
