Packaging bag with moisture-proof effect

Abstract

The invention relates to the technical field of packaging bags, and discloses a packaging bag with a moisture-proof effect. The packaging bag comprises a packaging bag body, wherein a top cover is fixedly installed at the top of the packaging bag body, and a sealing gasket extending into the packaging bag body is movably installed in the top cover. According to the packaging bag with the moisture-proof effect, through the arrangement of a stabilizing column, a rotating head, a spring and a connecting block, users can place the sealing gasket at the top cover and then rotate the rotating head so as to enable the stabilizing column to drive the sealing gasket to extrude; the spring can provide reverse force, so that the sealing gasket can be pressed down more stably, external moisture is notprone to entering the interior of the packaging bag body, and the moisture-proof effect is better; meanwhile, a protective cover and a desiccant layer are arranged, so that internal air is filtered,moist air is dried and absorbed, and the interior of the packaging bag body is kept dry, so that the moisture-proof effect of the packaging bag body is better, convenience is provided for the users, and the users can use the packaging bag more conveniently.

Description

technical field [0001] The invention relates to the technical field of packaging bags, in particular to a packaging bag with a moisture-proof effect. Background technique [0002] Packaging bag refers to the bag used to pack various supplies, which makes the goods convenient to transport and store during the production and circulation process. It is widely used in daily life and industrial production. Actual figures show that 80% of the plastic after use is Bags are finally transported to the landfill area for disposal like general garbage. Only 7% of the plastic is recycled and recycled. According to the production process, it is often divided into plastic packaging bags and composite packaging bags. Classified according to production materials: High-pressure polyethylene plastic bags, low-pressure polyethylene plastic bags, polypropylene plastic bags and PVC plastic bags, etc., classified by shape: vest bags, straight bags, three-dimensional bags, square bottom bags, seale...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a packaging bag with a moisture-proof effect, which has the advantages of good moisture-proof effect, etc., and solves the problem of packaging bags on the market. In practical applications, since most of the traditional packaging bags are open , convenient for loading, but its moisture resistance is not good, it is easy to cause the items inside the packaging bag to be damp, and at the same time, when the inside of the packaging bag is damp, it is easy to damage the items inside, affecting its life, and it is not convenient to store for a long time problem of use
