Abstract

本实用新型公开了一种食品包装用复合膜,它包括芯层和外层,在芯层上涂布了外层,该外层为聚乳酸层或聚乳酸共聚物层。本实用新型适合用于制作液体食品包装袋。

Description

食品包装用复合膜
本实用新型属于食品包装领域,具体地说是一种食品包装用复合膜。
在1991年公开的中国专利1055506A(申请号为90105802.5)介绍了一种三层塑料复合薄膜,但用这种复合薄膜较难制作有一定折叠形状的液体食品包装容器,而且,这种复合薄膜在自然条件下不易降解,不利于环境保护。
本实用新型的目的是针对述不足,研制出一种食品包装用复合膜。
本实用新型的实施方案是:一种食品包装用复合膜,包括芯层和外层,在芯层上涂布了外层,该外层为聚乳酸层或聚乳酸共聚物层。
本实用新型的优点是:它可以根据液体食品的包装需要,折叠成相应的包装形状,该食品包装用复合膜的外层为聚乳酸层或聚乳酸共聚物层,故较易在自然条件下降解。
图1是本实用新型的结构示意图。
下面结合附图及实施例对本实用新型作进一步说明。
如图1所示,本实用新型包括芯层1和二层外层2,外层2为聚乳酸层或聚乳酸共聚物层,该二层外层2分别被涂布于芯层1的上侧和下侧。芯层1为纸层,该纸层所用的材料主要是植物纤维或合成纤维。
本实用新型的的芯层1也可以为塑料层,该塑料层所用的材料主要是聚烯烃类。
本实用新型的芯层1也可以为铝箔层。
本实用新型的芯层1也可以由纸层和塑料层组成,纸层所用的材料主要是植物纤维或合成纤维,塑料层所用的材料主要是聚烯烃类。
本实用新型的芯层1也可以由纸层和铝箔层组成,纸层所用的材料主要是植物纤维或合成纤维。
本实用新型的芯层1也可以由铝箔层和塑料层组成,塑料层所用的材料主要是聚烯烃类。
