Easily-torn anti-pollution zippered bag

Abstract

The invention discloses an easily-torn anti-pollution zippered bag. A bag body is included. The upper portion of one side of an opening of the bag body is provided with three heat seal strips arrangedat intervals in parallel. A meshing zipper is arranged between the lower heat seal strip and the middle heat seal strip and is arranged on one side of a film inner layer in a heat seal manner. The two ends of the meshing zipper are in heat seal connection with bag films of located edge heat seal areas. The parts, at the critical point of the edge heat seal areas and the bag interior, of the meshing zipper are subjected to point seal connection through high-frequency ultrasonic waves. An easily-torn strip is arranged between the middle heat seal strip and the upper heat seal strip. An easy-pulling hole is formed in the edge heat seal area on one side of a bag body and located in one end of the easily-torn strip. Ultrasonic point sealing is used for the zipper, the problem that the criticalpoint does not have heat seal performance is solved, and bag seal performance is ensured; through the easy-pulling hole, a user can conveniently conduct tearing along the easily-torn strip, then, thezipper is stripped off, content leakage can be prevented, and pollution from powder is not likely to happen; and the meshing zipper and the easily-torn strip are combined and prevented from being rushed open by the content, and firmness is higher.

Description

technical field [0001] The invention relates to an easy-to-tear anti-pollution zipper bag, which belongs to the technical field of packaging bag production. Background technique [0002] The zipper bag is a type of bag that can be used multiple times. There are some disadvantages in the existing two-sided heat-sealed zipper bag. 2. When used as a powder packaging bag, the powder is easy to stick to the zipper, which affects the fastness of the zipper seal during repeated use of the zipper. It is easy to have powder leakage when the seal is opened, which is not conducive to Consumers have poor experience in using zippers. Contents of the invention [0003] In order to solve the problems in the prior art, the invention provides an easy-to-tear anti-pollution zipper bag. [0004] In order to achieve the above object, the technical means adopted by the present invention are: an easy-to-tear anti-pollution zipper bag, including a bag body, three parallel and spaced heat-seali...

AI Technical Summary

Problems solved by technology

[0002] The zipper bag is a type of bag that can be used for multiple times. The existing two-sided heat-sealed zipper bag has some disadvantages. 1. For the two-sided heat-sealed snap-fit ​​zipper ziplock bag, the zipper is easy to be opened by the contents, even to varying degrees. 2. When used as a powder packaging bag, the powder is easy to stick to the zipper, which affects the fastness of the zipper seal during repeated use of the zipper. When the seal is opened, it is easy to leak the powder, which is not conducive to Consumers have poor experience in using zippers
