Problems solved by technology

However, if the sealed filling part of the product is removed after filling the material, the material may come into contact with the mother and child zippers exposed on the inside of the bag, so that fine powder or liquid materials may enter between the mother and child zippers
In the case where the corner opening part of the zipper packaging bag is not opened, when the material enters the synthetic resin zipper of the opening part, the customer thinks that the corresponding product may be defective

Abstract

The present invention discloses a modified zipper packaging bag (1), wherein, wings (23, 24) are formed at both sides of a mother zipper (21) and a son zipper (22), the wings (23a, 24a) at one side of the mother zipper (21) and the son zipper (22) depart from each other and are heat bonded to the bilateral inside face (12, 13) of the packaging bag (1) along direction of one corner of the zipper packaging bag (1), the end of the wings (23b, 24b) at the other side of the mother zipper (21) and the son zipper (22) are mutually heat bonded together along the inward direction of the packaging bag (1) but not heat bonded to the bilateral inside face (12, 13) of the packaging bag (1), then materials filled in the zipper packaging bag (1) do not contact with the mother and son zippers.

Description

technical field [0001] [01] The present invention relates to an improved zipper packaging bag, and more particularly, to an improved zipper packaging bag, wherein a synthetic resin zipper is thermally bonded to a corner of the packaging bag at an inclination to form an opening portion, And to achieve automatic forming, in the zipper packaging bag products containing fine powder or liquid materials, unless the opening part is opened, the material will not touch the parent zipper and child zipper of the synthetic resin zipper. Background technique [0002] [02] Generally speaking, zipper packaging bags made of thermally bonded synthetic resin zippers have thermally bonded wings, with mother zippers and child zippers on both sides to form a synthetic resin zipper. The double-wing type synthetic resin zipper is constructed in such a way that direct thermal bonding parts are formed in the left, right and transverse directions of the upper end of the packaging bag. That is to say...
