Description
技术领域
本发明属于塑料膜技术领域，具体涉及一种用于包装的吸湿防潮塑料膜。
背景技术
塑料膜是采用聚氯乙烯、聚乙烯、聚丙烯、聚苯乙烯以及其他热塑性树脂制成的薄膜，用于包装，以及用作覆膜层。塑料包装及塑料包装产品在市场上所占的份额越来越大，特别是复合塑料软包装，已经广泛地应用于食品、医药、化工等领域，其中又以食品包装所占比例最大，比如饮料包装、速冻食品包装、蒸煮食品包装、快餐食品包装等，这些产品都给人们生活带来了极大的便利。
塑料膜虽然给人们带来了极大的好处，但是随着塑料膜的使用，给人们的生活及环境带来了很多问题，特别是对环境造成了非常大的污染。这都是由于塑料膜不能够及时降解导致的。即使塑料膜具有相当的负面影响，但是目前并不能将其舍弃，因此需要开发能够降解的塑料膜，以便在广泛使用塑料膜的前提下，尽可能地降低塑料膜带来的污染等负面影响。

优选的，所述热塑性树脂为聚氯乙烯、聚苯乙烯。
优选的，所述淀粉为甘薯淀粉，所述pH调节剂为碳酸钠。
优选的，所述热塑性树脂为聚氯乙烯。
一种用于包装的吸湿防潮塑料膜，它是由下述质量份的原料组成的：聚碳酸酯20-35份，聚氯乙烯32-42份，淀粉5-9份，木粉0.2-0.4份，硅藻土0.1-0.3份，陶土0.2-0.4份，硅酸钙0.1-0.3份，pH调节剂2-4份。
一种用于包装的吸湿防潮塑料膜，它是由下述质量份的原料组成的：聚碳酸酯30份，聚氯乙烯38份，淀粉7份，木粉0.3份，硅藻土0.2份，陶土0.3份，硅酸钙0.2份，pH调节剂3份。
优选的，所述热塑性树脂为聚苯乙烯。
一种用于包装的吸湿防潮塑料膜，它是由下述质量份的原料组成的：聚碳酸酯20-35份，聚苯乙烯35-45份，淀粉5-9份，木粉0.2-0.4份，硅藻土0.1-0.3份，陶土0.2-0.4份，硅酸钙0.1-0.3份，pH调节剂2-4份。
优选的，还包括钐0.6-0.8份和粗钪粉6-8份。
本发明的技术效果和优点：该用于包装的吸湿防潮塑料膜，通过加入钐，改善材料的结构，加快塑料的降解速度，通过加入钪，分解塑料，同时作为半引发剂，使塑料自发分解，从而加快降解速度，从而降低了对环境的危害；通过加入硅灰石，用于提高热塑性树脂的耐化学、耐湿性能，降低成型收缩率，增强尺寸稳定性、韧性、硬度、电和热的绝缘性，通过加入硅藻土，增强吸水性，同时增强绝热、绝缘的特性，木粉***廉，用于增强抗冲强度。
