Description

塑料杯注镀一体机及注镀灌封一体机 技术领域
本发明涉及塑料杯加工技术领域，特别地，涉及一种塑料杯注镀一体机。此外，本发明还涉及一种包括上述塑料杯注镀一体机的塑料杯注镀灌封一体机。
背景技术
塑料杯因具备成本低、输送方便、不易碎等优点而广泛应用于食品、制药、化工等领域中，特别适用于果冻类、颗粒类、粉剂类等大批量的产品的包装。
然而，塑料杯由熔融状塑料颗粒注塑获得，塑料杯相对于金属杯或者玻璃杯的阻隔性相对较低，气体容易透过而影响产品的品质，导致塑料杯包装品无法长久保存，且塑料杯的杯口为敞口状，在没有覆膜密封而进行转运封口的过程中，或者在易揭膜撕开后而需要重新覆膜封口的过程，容易受到外界环境的污染而报废，且包装质量欠佳。
现有的塑料杯的加工，往往采用注塑工艺注塑成型，如中国实用新型专利CN213006415U，其阻隔性仅取决于塑料自身的性质以及加工时的尺寸要求，而塑料杯在同等尺寸要求下，阻隔性也往往低于金属杯和玻璃杯。
发明内容
