1. Even the packaging is very particular! If the buyer can finish it in a short time, you don't need to spend too much on packaging.
To maintain the flavor in the long term, efforts need to be made in the packaging method and packaging of coffee. Gas with high gas resistance can effectively block oxygen and water vapor. Without such an internal environment, over time, it becomes difficult to ensure the quality of coffee.
3. Sell packaging materials for coffee beans and coffee powder. Previously, many coffee products were canned, but later there was flexible packaging. After the emergence of flexible packaging, it only started with simple bags. Later on, in order to prevent coffee beans from spoiling, it gradually developed into a special packaging bag with preservation function. This type of preservation bag is made of multi-layer thin film bonding, and the middle layer is made of high resistance material. Different cling bags have different effects, which is related to the seller's business philosophy. This is very important for a cup of coffee! The theory of packaging preservation is actually very simple. It is easy to remove the oxygen and water that can cause coffee beans to spoil.
What are four methods for sealing tea and coffee packaging?

2. It is a one-way exhaust valve. Unidirectional means that the bag can only be lifted out from the inside and cannot be carried outside. Coffee beans release carbon dioxide after baking. By using a one-way exhaust valve, carbon dioxide, oxygen, water, etc. Take them out of the bag together, but the process is quite lengthy. If the inert gas replacement method cannot be used for mixing, the preservation effect is not significant.
3. Vacuum packaging method. This is simply allowing air to enter the air, but the ratio of oxygen and water in nature does not decrease, and the effect is not very good.
4. Oxygen. This method uses chemical methods to absorb oxygen and water, but it also absorbs some carbon dioxide and fragrance, which is regrettable.
Tea and coffee packaging: Why are sealed coffee beans swollen compared to coffee beans?
