Abstract

The invention is applicable to the technical field of check valves, and provides a gas exhaust valve for a packaging material. The gas exhaust valve for the packaging material comprises the packaging material provided with a first through hole, and further comprises a gas exhaust valve connected with the packaging material and used for performing gas exhaust motion on the packaging material. The gas exhaust valve comprises a first bonding layer and a second bonding layer. The first bonding layer is used for bonding the packaging material through gas pressure in the packaging material, and the first bonding layer is used for promoting gas in the packaging material to be exhausted through the first through hole in the mode of bonding the packaging material, driving the second bonding layer to bulge and forming an open channel. According to the gas exhaust valve for the packaging material, gas in the packaging material can be automatically exhausted, and after the gas is exhausted, the packaging material can be sealed.

Description

technical field [0001] The invention belongs to the technical field of check valves, in particular to a gas discharge valve for packaging materials. Background technique [0002] Usually, food needs to go through various distribution processes after production before being passed on to final consumers for use. During the flow and storage process of the food, it will be affected by various internal and external influences including temperature, humidity, heat, light, chemical changes of the food itself and microorganisms, etc., and because of the above-mentioned internal and external factors , During the distribution and storage of food, the function of food or the loss of value as a commodity may occur. [0003] For existing food, the gas expanded inside the food is discharged from the packaging material basically by means of a check valve or a gas discharge cover. [0004] The existing device is not only expensive, but also cannot quickly and effectively discharge the gas...
