Description

一种高阻隔性的GL膜屋顶包结构
技术领域
本发明涉及包装盒领域，具体是一种高阻隔性的GL膜屋顶包结构。
背景技术
现有的包装盒中，尤其是对于食品包装而言，其在内层会使用大量的铝箔，用来起到隔绝阻氧效果，这导致一方面对铝的需求量较大，另一方面在处理时容易产生有毒气体，导致对环境的污染较大，随着全球对环保的要求逐渐提高，铝箔等阻隔材料的使用已经无法满足使用的需求。
发明内容
本发明的目的在于提供一种高阻隔性的GL膜屋顶包结构，它能够具备更好的阻隔效果，且性能更加稳定，处理时不易产生污染，使包装材料具备更好的环保性。
本发明为实现上述目的，通过以下技术方案实现：
一种高阻隔性的GL膜屋顶包结构，包括自外向内依次设置的外PE层、纸基层、中PE层、GL膜层、内PE层，各层通过复合成为一个整体。
进一步的，所述外PE层、中PE层、内PE层为聚乙烯材质或者乙烯丙烯酸材质。
进一步的，所述内PE层由两层PE层组成。
进一步的，所述GL膜层为硅和氧化铝进行蒸镀加工形成的透明材质。
对比现有技术，本发明的有益效果在于：
本发明利用GL膜代替铝箔用于食品的包装中，其能够具有优异的对氧气、水蒸气的阻隔性，对内装物的保香性，可以长期保存食品的鲜度；具有优异的耐热性能，适合于蒸煮包装袋，实现对食品更好的贮存效果；对氧气、水蒸气的阻隔性不受温度、湿度的变化而发生减弱；在焚烧时不会产生有毒气体，也不会有气体残留，减少了铝材的使用量，使包装的环保效果进一步提高。
附图说明
附图1是本发明的结构示意图。
附图中所示标号：
1、外PE层；2、纸基层；3、中PE层；4、GL膜层；5、内PE层。
具体实施方式
下面结合具体实施例，进一步阐述本发明。应理解，这些实施例仅用于说明本发明而不用于限制本发明的范围。此外应理解，在阅读了本发明讲授的内容之后，本领域技术人员可以对本发明作各种改动或修改，这些等价形式同样落于本申请所限定的范围。
本发明所述是一种高阻隔性的GL膜屋顶包结构，主体结构包括自外向内依次设置的外PE层1、纸基层2、中PE层3、GL膜层4、内PE层5，各层通过复合成为一个整体，在纸基层2的内部设置GL膜层4，从而取代现有的铝箔或者PVDC涂层薄膜，从而起到阻隔效果，GL膜层4是一种透明蒸镀薄膜，可将PET和ONY进行硅和氧化铝进行蒸镀加工，制成具有优异的氧气阻隔性、防潮性、保香性能的透明高阻隔环保薄膜，这种薄膜的使用，其能够具备优异的阻氧和阻水性能，且性能竖直不受温度和湿度的影响，在处理燃烧时不易产生有害气体残留，使得包装具备更好阻隔效果的同时，环保效果大大提升。
优选的，所述外PE层1、中PE层3、内PE层5为聚乙烯材质或者乙烯丙烯酸材质，使用现有市场上的的材质制作成为PE层，不对其具体成分进行改进，能够适用于食品等的包装使用。
优选的，所述内PE层5由两层PE层组成，使得对内部食品尤其是液体具备更好的隔绝效果，从而大大提高对内部食品的贮存时间。
优选的，所述GL膜层4为硅和氧化铝进行蒸镀加工形成的透明材质，可直接进行符合和印刷，提高了生产的便捷性，同时可减轻包含的重量，利用金属探测器对内部进行无针孔检查，实现对食品内部异物的高效检测。
