Abstract

本实用新型公开了一种压纹折叠铝塑膜，包括依次紧贴的压纹层、热封层、印刷层、底涂层、铝箔层、热熔胶粘合层、基底薄膜层。本实用新型较常规纸、铝、膜包装材料具有高阻隔性，同时较常规薄膜有优异的折叠成型性。

Description

一种压纹折叠铝塑膜
技术领域
本实用新型涉及一种压纹折叠铝塑膜，属于包装材料技术领域。
背景技术
块状食品包装材料主要由以下两种方式生产：
1、由基底纸张加涂热熔胶后与铝箔通过湿法复合而成，为了满足包装的需求，还会在铝箔表面印刷图案或者压纹。但由于热熔胶涂布时的黏度较高，涂布后的致密性较差，随着时间推移，外部水汽会进入内容物，导致产品发生变质，影响食品质量和人身健康。此包装方式折叠性好但阻隔性差；
2、薄膜印刷后与纸张、铝箔通过干湿法复合完成粘合。为改善薄膜折叠性，通常与铝箔使用干湿法复合，因干湿法复合涂胶量较低，铝箔经折叠后后出现裂痕，降低了铝箔的阻隔效果，此外，包装后表层为薄膜印刷图案，较铝箔压花包装档次也低。
发明内容
本实用新型提供一种压纹折叠铝塑膜，解决的技术问题是提高产品的折叠性和阻隔性。
本实用新型是通过以下的技术方案实现的：
本实用新型公开了一种压纹折叠铝塑膜，包括依次紧贴的压纹层、热封层、印刷层、底涂层、铝箔层、热熔粘合层、基底薄膜层。
本实用新型的有益效果为：较常规纸、铝、膜包装材料具有高阻隔性，同时较常规薄膜有优异的折叠成型性。
附图说明
图1是本实用新型的结构示意图
具体实施方式
以下结合附图，对本实用新型做进一步说明。
如图1是本实用新型的结构示意图，一种压纹折叠铝塑膜，包括依次紧贴的压纹层1、热封层2、印刷层3、底涂层4、铝箔层5、热熔胶粘合层6、基底薄膜层7，铝箔层5与基底薄膜层7通过热熔胶粘合层6实现粘合，热熔胶粘合层6弥补了铝纸折叠后的裂痕提高产品阻隔性能，压纹层1提高了产品的包装档次。
以上显示和描述了本实用新型的基本原理、主要特征和本实用新型的优点。本行业的技术人员应该了解，本实用新型不受上述实施例的限制，上述实施例和说明书中描述的只是说明本实用新型的原理，在不脱离本实用新型精神和范围的前提下本实用新型还会有各种变化和改进，这些变化和改进都落入要求保护的本实用新型范围内。本实用新型要求保护范围由所附的权利要求书及其等同物界定。
