One Way Plastic Exhaust Valve
Introduction of one-way exhaust valve:
1. For coffee beans, feed and other products that can volatilize their own gas, the container of the packaged products will expand, especially when using composite bags. In addition to changing the shape of the original packaging, the gas produced by the continuous fermentation of the product will even cause the packaging explosion and cause serious losses to the manufacturers.
2. Then the usual way to solve this problem is to weld a one-way exhaust valve on the packaging bag, so that the excess gas in the packaging bag can be discharged smoothly, so as to ensure the quality of the contents in the packaging bag and eliminate the risk of packaging expansion or bursting. In addition, the one-way exhaust valve can prevent the oxygen from entering the bag, which will cause the product in the bag to oxidize and deteriorate. The exhaust valve with a filter screen filters the powder in the packaging bag to prevent the powder from spraying out of the bag and causing pollution.
Other functions of one-way exhaust valve:
1. Because a one-way vent valve is set on the plastic packaging bag, the residual air in the lower bag is discharged from the one-way vent valve under the gravity of the goods in the upper packaging bag during the stacking process of the packaging bag filled with goods, which can improve the stability of the stacking and increase the stacking height.
2. The impact resistance of plastic packaging bag is improved. When the packing bag filled with goods falls down at the height of carrying goods, the air in the bag can be discharged from the one-way exhaust valve, so as to reduce the shock wave caused by the residual air in the bag and reduce or avoid the resulting package breakage.
