Description
本发明涉及包装袋加工机械领域，尤其涉及一种具有三角结构侧风琴的包装袋及其加工设备和方法。
包装袋是指用于包装各种用品的袋子，使货物在生产流通过程中方便运输，容易存储，广泛用于日常生活和工业生产中。侧风琴为包装袋的两侧片料结构，与包装袋上膜、下膜和主膜结合形成包装袋袋体。传统包装袋的侧风琴采用方形片结构，经过翻折烫压在上膜和下膜之间，翻折后的侧风琴以折痕为中线形成双边结构。拉链结构安装在上膜、下膜和侧风琴双边结构上，作为包装袋的启封结构。侧风琴的双边结构作为启封结构的安装部分之一，一方面侧风琴上增加安装拉链的工艺，易造成安装部位受外力作用易破裂，另一方面在打开包装袋的过程中双边结构极为容易造成撕裂，使用效率低下。
此外，侧风琴采用方形片结构，传统的加工工艺中，侧风琴与上膜、下膜和底膜的原始膜材为两片膜材，分别印刷切割，增加操作工艺和设备，加工成本增加，若将侧风琴与上膜、下膜和底膜设置在一片原始膜材上进行加工，由于方形片结构的侧风琴长宽与上膜或下膜的长宽无法做到一致，就需要使用更多的膜材来适应侧风琴的长度，占用面积大，材料浪费严重。
