Description
技术领域
本发明属于包装袋材料技术领域,尤其涉及一种全生物降解高阻隔多层复合材料及其制备方法和包装袋。
背景技术
当前,我们生活的环境中随时可见的塑料废弃物对于环境的污染,它主要包括塑料袋、塑料制品等,这些塑料垃圾在自然环境中500年都无法降解,严重危害人类和动植物。面对日益严重的白色污染问题,人们希望寻找一种能替代现行塑料性能,又不造成白色污染的塑料替代品,可降解塑料应运而生,这种新型功能的塑料,其特点是在达到一定使用寿命废弃后,在特定的环境条件下,引起某些性能损失及外观变化而发生生物降解,对自然环境无害。
虽然现有的生物降解塑料能够制造成垃圾袋、购物袋等,减少白色塑料污染,但仅限于满足日常生活使用,其他复杂的功能性包装袋,比如高温蒸煮、低温冷藏、真空保鲜等包装技术难题无法实现,而且现有的生物降解塑料还存在透氧率较高、阻隔性差等问题。
