Exhaust Valve on the packing bag of Coffee beans-the Design of the packing bag of Coffee beans

1. Roasted coffee beans are sealed and packaged in aluminum foil bags to prevent coffee beans from coming into contact with light and air, resulting in rapid fragrance emission and oxidation.

two。 The "one-way exhaust valve" coffee bag can insulate the light and air from outside the bag, so that the coffee beans can keep the fresh original taste of the coffee beans in the best state of preservation and packaging.

3. Roasted coffee beans will naturally emit carbon dioxide, such as accumulation in the bag will affect the quality of coffee beans, and the "one-way exhaust valve" on the bag can let the excess gas out of the bag, and the coffee can squeeze the bag to smell the fragrance.

This kind of packaging is to design a valve with a double-layer structure made of thin film on the seal of the bag. after loading the baked beans, the carbonic acid gas produced after baking will be discharged from the valve, and the outside gas can not enter the bag. can effectively maintain the original aroma and essence of roasted coffee beans. This is currently the most recommended packaging method for roasted coffee beans, and coffee products with this packaging should be selected as far as possible.

To put it more popularly, this air valve is only inaccessible. After roasting, coffee beans will produce gases such as carbon dioxide, which need to be discharged slowly. On the other hand, the one-way exhaust valve is encapsulated on the coffee bag, and a hole is pierced on the surface of the bag in the position of the one-way valve, so that the carbon dioxide precipitated from the baked coffee beans can be automatically discharged out of the bag, but the air from the outside can not enter the bag. It effectively ensures the dry and mellow flavor of coffee beans, and will not cause the bags to open because of the accumulation of carbon dioxide, and at the same time prevent coffee beans from being accelerated by external air.

The main results are as follows: 1. The one-way exhaust valve of the coffee bag can prevent the external air from entering the coffee bag and prevent the inner package from being oxidized and contaminated. It is mainly used in the flexible packaging of coffee bags, storage bags, fresh-keeping bags and so on.

2. Because an one-way exhaust valve is arranged on the plastic bag, the bag full of goods is in the process of stacking. The residual air in the lower part of the bag is on top, and the goods in the bag are removed from the one-way exhaust valve under the action of gravity, which can improve the stability of stacking and increase the height of stacking.

3. The anti-impact ability of plastic bags is improved. When the bag full of goods falls at the height of handling the goods, the air in the bag can be removed from the one-way exhaust valve to reduce the shock wave caused by the residual air in the bag and reduce or avoid the resulting package breakage.
