Abstract

本实用新型涉及一种自由导气真空包装袋，包括包装袋袋体，袋体上设有单向排气阀或单向排气咀，其特征是：至少在包装袋袋体的装有单向排气阀或单向排气咀一侧内壁上，或与之相对侧内壁上，设有凸出于内壁的条纹状或网格状导气通道，当包装袋袋体内壁相互贴合时，导气通道与单向排气阀或单向排气咀的排气口联通。其优点是：制袋工艺简单、真空包装袋排气流畅、抽真空效果好。

Description

自由导气真空包装袋
技术领域：
本实用新型涉及一种自由导气真空包装袋，属于真空包装领域。 
背景技术：
市场上的真空包装袋，一般是在袋体上设有单向排气阀或单向排气嘴，用于对包装袋袋抽真空。对于软体真空包装袋，其弊病是在抽真空过程中，袋体在负压作用下会收缩变形，袋体的相对面会往一起贴合，如果袋中只剩少量物品时，抽真空比较困难。因为袋体的两相对面会提前紧贴，将排气阀嘴封闭，造成袋内剩余气体无法排出。 
发明内容：
本实用新型的目的是针对软体真空包装袋的弊病，提供一种自由导气真空包装袋。
本实用新型的目的是通过以下方式实现的： 
本实用新型包括包装袋袋体，袋体上设有单向排气阀或单向排气嘴，其特征是：至少在包装袋袋体的装有单向排气阀或单向排气嘴一侧内壁上，或与之相对侧内壁上，设有凸出于内壁的条纹状或网格状导气通道，当包装袋袋体内壁相互贴合时，导气通道与单向排气阀或单向排气嘴的排气口联通。 
本实用新型的优点是：制袋工艺简单、真空包装袋排气流畅、抽真空效果好。 
附图说明：
图1为本实用新型的外形示意图； 
图2为本实用新型的袋体展开示意图。 
具体实施方式：
参照附图，本实用新型包括包装袋袋体1，袋体上设有单向排气阀或单向排气嘴2，至少在包装袋袋体的装有单向排气阀或单向排气嘴一侧内壁上，或与之相对侧内壁上，设有凸出于内壁的条纹状或网格状导气通道3，当包装袋袋体内壁相互贴合时，导气通道与单向排气阀或单向排气嘴的排气口联通。导气通道可以制成联通单向排气阀或单向排气嘴的排气口的一个图案(如田字形图案、米字形图案等)，也可以是联通单向排气阀或单向排气嘴的排气口的条带状，还可以是均匀布满袋体一面内壁或整个内壁的。 
本实用新型主要适用于软体真空包装袋，包括三边封拉链袋，多边封自立 袋，各类固态定型产品包装袋，多边封双面进出口盖真空袋，多边封自立进出口盖真空袋等类真空包装袋产品。
