Description

自粘收缩阻隔膜
技术领域
本发明涉及包装材料应用领域，特别是一种自粘收缩阻隔膜。
背景技术
目前所使用的自粘收缩阻隔膜，大多为PE膜，现有的PE收缩膜进行两层包装后，外层PE收缩膜和内层PE收缩膜容易发生粘连，导致拆卸外层PE收缩膜时，容易破坏内层PE收缩膜，影响小包装商品的陈列，并且包装膜不具有防腐抗菌的效果，这就使得包装食品的保质期非常的短，过期的包装食品只能扔掉，造成极大的浪费。
发明内容
本发明的目的是为了解决上述问题，设计了一种自粘收缩阻隔膜。
实现上述目的本发明的技术方案为，一种自粘收缩阻隔膜，该包装膜的结构是由5层或者7层复合材料复合而成的，所述5层复合材料由外到内依次包括POE膜层1，TIE膜层2、PA膜层3、TIE膜层2和EVA膜层4。7层复合材料由外到内为POE膜层1，TIE膜层2、VLDPE膜层5、EVOH膜层6、PA膜层3、TIE膜层2和EVA膜层4。
相邻两层之间可在低温条件下自粘封合。
EVOH膜层为高阻隔膜层。
利用本发明的技术方案制作的自粘收缩阻隔膜，有益效果是，不会使各层膜之间发生粘连，适合小包装商品的陈列，具有抗菌效果，延长了食品的保质期。
附图说明
图1是本发明所述自粘收缩阻隔膜5层的结构示意图；
图2是本发明所述自粘收缩阻隔膜7层的结构示意图；
图中，1、POE膜层；2、TIE膜层；3、PA膜层；4、EVA膜层；5、VLDPE 膜层；6、EVOH膜层。
具体实施方式
下面结合附图对本发明进行具体描述，如图1-2是本发明所述自粘收缩阻隔膜的结构示意图，一种自粘收缩阻隔膜，该包装膜的结构是由5层或者7层复合材料复合而成的，所述5层复合材料由外到内依次包括POE膜层，TIE膜层、PA膜层、TIE膜层和EVA膜层。7层复合材料由外到内为POE膜层，TIE膜层、VLDPE膜层、EVOH膜层、PA膜层、TIE膜层和EVA膜层；相邻两层之间可在低温条件下自粘封合；EVOH膜层为高阻隔膜层。
本实施方案的特点为，该包装膜的结构是由5层或者7层复合材料复合而成的，所述5层复合材料由外到内依次包括POE膜层，TIE膜层、PA膜层、TIE膜层和EVA膜层。7层复合材料由外到内为POE膜层，TIE膜层、VLDPE膜层、EVOH膜层、PA膜层、TIE膜层和EVA膜层。POE膜层具有高弹性、高强度的特点，具有优异的力学性能、流变性能和抗紫外线性能，TIE膜层提高了包装膜的韧性，增强粘合附着力，PA膜层耐磨、强韧、氧气透过率低，EVA膜层具有优良的柔韧性、耐冲击性、弹性、光学透明性、低温绕曲性、黏着性、耐环境应力开裂性、耐候性、耐化学药品性、热密封性等，VLDPE膜层在塑料包装薄膜领域，可作为软化改性剂，撕裂强度改性剂，冲击改性剂与EVA混合可改善强度，性能，柔软性和低温热合性能，EVOH膜层显著特点是对气体具有极好的阻隔性和极好加工性，另外透明性、光泽性、机械强度、伸缩性、耐磨性、耐寒性和表面强度都非常优异。
上述技术方案仅体现了本发明技术方案的优选技术方案，本技术领域的技术人员对其中某些部分所可能做出的一些变动均体现了本发明的原理，属于本发明的保护范围之内。
