Instant Coffee Bag Packaging

People often talk about the saying "the fresher the coffee, the better." but it is not the truth. But as soon as the raw coffee beans are roasted, there are two opposing forces that repel them, which determines when the best flavor state of the coffee occurs. These two forces are exhaust and oxidation.

The packaging of coffee beans is also very important. Most coffee beans are packaged in one-way valve bags lined with aluminum foil. The aluminum foil blocks light and air, and the one-way exhaust valve acts to expel excess carbon dioxide. But the bag is useless after you get the beans. Because once the bean raising is done, there is no need to let it vent any more. When you press around the exhaust valve and smell the coffee aroma, in addition to the carbon dioxide, many aromas are also exhausted and lost. Because the bag with the one-way exhaust valve will discharge too much aroma, even if it can be repeatedly sealed, it is not suitable for long-term use. Therefore, it is necessary to replace the container seal to preserve coffee beans. The airtight can is the first choice. Try to choose an opaque airtight can without peculiar smell. In addition, a sealed can is not necessarily the same as sealing. Most airtight cans will leak a bit, which is normal. And there is also air in the tank, and the coffee beans will continue to oxidize at a slower rate. So sealing is to prolong the life of freshness.

Classification of aluminum foil packaging bags: there are aluminum foil bags for food, aluminum foil bags for industrial life, medical aluminum foil bags, electronic aluminum foil bags, etc. Food refers to packaged foods such as: dried fruits, meat, snacks, coffee, daily chemicals; coffee packaging bags It can be packaged in aluminum foil bags, which can effectively isolate oxygen and prevent coffee beans from being wet and oxidized.
