Nowadays, people's living standards are constantly improving, and their work is getting busier and busier. In recent years, coffee has become the favorite drink for young people. When you are sleepy at work, you can have a cup of coffee when you stay up late at night. How do you make these coffee bags? Why are coffee bags different from other product bags? Some have an exhaust vent? Today, the manufacturer of coffee bean packing bag comes to tell you why.

1: Why is coffee bean packing bag easy to flatulence
Due to the natural carbon dioxide produced by coffee beans after baking, direct packaging is easy to cause package damage, and long-term exposure to the air will cause aroma loss and lead to the oxidation of oil and aromatic components in coffee, resulting in the decline of the quality of finished products. Therefore, the packaging material of coffee beans is more important.
2: Why is an exhaust valve added to the coffee bag
There is an exhaust valve on the packing bag of coffee beans. This exhaust valve is called one-way exhaust valve. The purpose of this exhaust valve is to let the air only go out, but not into it. Because the coffee beans will produce carbon dioxide after baking, the sealed packaging bag will inflate, which will affect the quality of coffee beans. Therefore, a one-way exhaust valve must be added to the bag One way exhaust valve coffee bag.
Coffee beans will continue to release carbon dioxide several times the volume of coffee beans after baking. In order to prevent the coffee packaging from bursting and isolating from sunlight and oxygen, a one-way exhaust valve is designed on the coffee bag to drain the excess carbon dioxide out of the bag.
In addition, the one-way exhaust valve can also prevent the oxygen from entering the coffee bag, so as to avoid the oxidation of coffee beans and the rapid emission of fragrance, so as to absolutely ensure that the flavor of coffee beans remains unchanged. Of course, when you buy coffee, you can squeeze the bag and smell the coffee through the coffee exhaust valve!
