Coffee bag one-way exhaust valve -V1 type - beans valves

1, the one-way exhaust valve is encapsulated in a coffee bag above the surface of the bar and the hole in the bag package check valve position, the carbon dioxide can be precipitated beans after roasting automatically discharged outside the bag, the outside air can not enter the bag . Effectively guarantee the beans dry and mellow flavor, not because of the accumulation of carbon dioxide in order to open up the bag, to prevent contamination within the packaging material is oxidized deterioration. Mainly used bags storage bags, storage bags, feed bags and other needs flexible way revealing gas. 2, since the plastic bag provided above a one-way exhaust valve, the bag filled with goods in the stacking process, the residual air in the bag body at the lower portion of the upper portion of the packaging bag by gravity from a cargo-way discharge valve, can improve the stability of the stack, increasing the stacking height. 3, to improve the impact resistance of plastic bags, when filled with cargo bags during transport or falls from a height, the air bag from a one-way discharge valve, reducing the shock wave generated by the residual air bag to reduce or avoid the resulting broken packages. I produced a one-way valve is used PE materials and food-grade silicone made of food-grade products are 100% tested, stable and reliable quality, welcome to order.
