The packaging of roasted coffee beans (powder) is the most diverse in coffee packaging. As coffee beans will naturally produce carbon dioxide after baking, direct packaging is easy to cause packaging damage, and long-term contact with the air will cause aroma loss and lead to the oxidation of oil and aromatic components in coffee, resulting in quality decline. Therefore, the packaging of coffee beans (powder) is particularly important·

There are many kinds of coffee packages and various materials. Don't think that coffee packaging is what kind of colorful small bags you usually see. In fact, the world of coffee packaging is wonderful. Here is a brief introduction to the knowledge of coffee packaging.
According to the form of coffee supply, coffee packaging can be basically divided into three categories: export packaging of raw beans, packaging of roasted coffee beans (powder), and packaging of instant coffee.
Roasted coffee beans (powder) packaging
It is generally divided into bags and cans.
(1) . bagged:
Bags are generally divided into: non airtight packaging, vacuum packaging, one-way valve packaging, pressurized packaging.
Non airtight packaging:
In fact, it is a temporary packaging, which is only used for short-term storage.
The roasted coffee beans need to be placed for a period of time before packaging to prevent the damage of carbon dioxide to the packaging. Such packaging can generally be stored for about 10 weeks.
Check valve packaging:
A one-way valve is added to the packaging bag to allow the generated carbon dioxide to be eliminated, but it will block the entry of external gases, ensuring that the coffee beans will not be oxidized but will not prevent the loss of aroma. Such packaging can be stored for up to 6 months. Some coffees are also packaged with vent holes, that is, only vent holes are made on the packaging bag without installing a check valve, so once the carbon dioxide generated by the coffee beans is emptied, the outside air will enter the bag, causing oxidation, so its storage time will be greatly reduced.
After roasting, the coffee beans are quickly vacuum packed and then filled with inert gas for sealing. Such packaging can ensure that the coffee beans will not be oxidized and the aroma will not be lost. It has sufficient strength to ensure that the packaging will not be damaged by air pressure, and can be stored for up to two years
(2) . canned
Cans are generally metal and glass, and both are equipped with plastic covers for easy sealing.
Instant coffee packaging
The packaging of instant coffee is relatively simple. Generally, it is packed in small sealed bags, mainly in long strips, and there is also an outer packaging box. Of course, canned instant coffee is also used in some markets
texture of material
Different kinds of coffee packaging have different materials. Instant coffee packaging has no special material requirements, and basically uses general food packaging materials. However, due to the requirements of anti-oxidation, coffee bean (powder) packaging generally adopts light tight plastic composites and relatively environmentally friendly kraft paper composites.
Coffee is one of the three soft drinks in the world and the second largest trading product in the world after oil. Its popularity can be seen. The coffee culture contained in its packaging is also charming due to its long-term accumulation
