Description

铝塑复合瓶盖密封片
本实用新型涉及一种瓶类密封片。
近年来出现了铝箔纸板复合材料封口。这种材料提高了密封性能，但由于纸板易吸潮及瓶口启封后，瓶内液体或膏状物料吸附于纸板中，造成纸板糊化及霉变。另外，由于纸板弹性差，再封闭性大为降低。
本实用新型的目的在于提供一种具有再封闭性能好的铝塑复合密封片。
本实用新型的技术方案是：包括铝箔层、发泡塑料层，其特征在于：铝箔层和发泡塑料层之间涂有蜡类混合物粘贴层，铝箔层的另一面涂有热熔性粘接层。
本实用新型的优点是：使用方便，只要将铝塑复合瓶盖密封片直接安装在瓶盖内，当此瓶在生产流水线上，经过专用高频感应封口机时，就能瓶口密封，而且再密封性能好。
现结和附图和实施例对对本实用新型说明如下：
图1：为本实用新型结够示意图；
图2：为本实用新型使用情况示意图；
本实用新型的实施例为：依此由热熔性粘接层1、铝箔层2、蜡类混合物粘贴层3、发泡塑料层4构成的层状结构，所述的铝箔层2和发泡塑料层4之间涂有蜡类混合物粘贴层3，铝箔层2的另一面涂有热熔性粘接层4。
使用时，只要将该密封片直接安装在瓶盖内，旋紧瓶盖，当此瓶在生产流水线上，经过专用高频感应封口机时，涂有热熔性粘接层1自动熔化，将瓶口和铝箔层2密封；同时，蜡类混合物粘贴层3自动熔化，即铝箔层2与发泡塑料层4自动分离。当用户打开瓶盖，开启铝箔层2时，瓶盖上的发泡塑料层4可起到再密封作用。
