Zipper Lock Air Valve Self-Supporting Coffee Bean Powder Granule Pack Matte Black Packaging Pouch

The one-way air valve prevents external air from entering the bag and prevents the inner package from being oxidized, contaminated and deteriorated.Mainly used in packaging bags, storage bags and other flexible packaging that require one-way air leakage. The one-way exhaust valve is different from other products in that the one-way exhaust valve has a filter screen which can isolate the influence of the powder material on the exhaust valve. at the same time, it has the function of allowing the gas in the bag to be discharged while preventing the solid (including dust) from flowing out of the bag, and ensuring that the external air cannot enter the bag. Because an one-way exhaust valve is arranged on the plastic bag, the residual air in the lower part of the bag is discharged from the one-way exhaust valve under the gravity action of the goods in the upper bag during the stacking process of the bag filled with goods. it can improve the stability of stacking and increase the height of stacking. The impact resistance of the plastic bag is improved. When the bag full of goods is transported or falls from a height, 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.
