Description

双密封包装袋
本实用新型涉及包装袋,尤其是关于一种自封带和热合封带设在袋体二端的双密封包装袋。
双密封包装袋是指在袋体上设有二条密封带:自封带和热合封带。包装袋一般是以软质塑料、铝箔复合膜为材料制成,它是用来解决非一次性用完物品的密封保存问题。一般常用的双密封包装袋,二个密封带都是设在袋体的一端,也就是说两个密封带都位于包装袋袋体中所装物品的上方或下方。具有这种结构的双密封包装袋在进行封装物品作业时,首先要增加将袋体上已制作好的指压式自封带拉开的工序,然后放入物品,抽真空再热合封口,这样就影响工作效率。并由于袋中装入物品后袋口位置的移动,抽真空后,指压式凹凸槽自封口可能由于错位而形成不密封及自封带不平整,影响包装质量,既不美观,又在运输过程中还可能引起软质塑料包装袋的破裂。
为此,本实用新型的目的是提供一种双密封包装袋,袋体上的二个密封带:自封带和热合封带分别设在包装袋袋体的二端,既能解决非一次性用完物品密封保存问题,又能提高包装质量和工作效率。
本实用新型是这样实现的:一种双密封包装袋,其结构包括袋体、自封带和热合封带。自封带设于袋底一端,而热合封带则设于袋体的另一端开口处,在袋底两侧边上各设有撕裂口。自封带可以是单轨、双轨指压式自封带或拉链式自封带。袋体可以是长方形或圆桶形。
由于本实用新型二个密封带设在袋体的二端,就是说自封带设在袋底一端,而热合封带则设在袋体的另一端开口处,物品封装于二个密封带之间。这样结构的包装袋在进行物品封装作业时,只须从预先已制成的设有自封带图5和图6所示的双轨指压式自封带和拉链式自封带。
包装袋袋体2也可以如图7所示采用的圆桶形袋体,以便于封装圆形的物品。
