Roasted coffee beans (powder) packaging is the most versatile form of coffee packaging. Because coffee beans naturally produce carbon dioxide after being roasted, direct packaging can easily cause packaging damage, and prolonged contact with air can cause aroma loss and lead to fat and aroma in coffee. Ingredients are oxidized causing quality degradation. Therefore, the packaging of coffee beans (powder) is particularly important. At present, it is generally divided into bags and cans.
Bags are generally divided into: non-airtight packaging, vacuum packaging, one-way valve packaging, pressurized packaging.
It is actually a temporary packaging, only for short-term storage
Roasted coffee beans need to be stored for a period of time before being packaged to prevent carbon dioxide from damaging the packaging. Such packaging can generally be stored for about 10 weeks.
Check valve packaging
Adding a one-way valve to the packaging bag allows the generated carbon dioxide to be eliminated but will prevent outside air from entering, ensuring that the coffee beans are not oxidized but cannot prevent the loss of aroma flow. Such packages can be stored for up to 6 months. There are also some coffees that use vent holes, that is, the vent holes are only punched in the packaging bag without a one-way valve. This way, once the carbon dioxide generated by the coffee beans is evacuated, the outside air will enter the bag, causing oxidation, so its storage Time is greatly reduced.
After roasting the coffee beans, they are vacuum-packed and then filled with an inert gas to seal them. This type of packaging can ensure that the coffee beans are not oxidized and the aroma is not lost. There is sufficient strength to ensure that the package is not damaged by air pressure. Two years.
Cans are generally made of metal and glass, with plastic lids for easy sealing.
Instant coffee packaging
Instant coffee packaging is relatively simple. Generally, small sealed bags are used. At present, it is mainly packed in long strips. In addition, outer packaging boxes are also available. Of course, there are also canned instant coffee supplies on the market.
4 Material editing
The material of different types of coffee packaging is not the same. Generally, the raw material for raw bean export packaging is relatively simple, which is the material of ordinary sacks. There is no special material requirement for instant coffee packaging. Basic food packaging materials are basically used. The coffee bean (powder) packaging generally uses opaque plastic composite materials and more environmentally friendly kraft paper composite materials due to the requirements of oxidation prevention.
5 color editing
The color of coffee packaging also has certain rules. According to the conventions formed in the industry, the color of the finished coffee packaging reflects the characteristics of the coffee to a certain extent. The red packaging coffee is generally thick in taste and can allow drinkers to quickly recover from their good dreams last night Sober up; black-packed coffee belongs to high-quality small fruit coffee; gold-packed coffee symbolizes richness, indicating that it is the best in coffee; blue-packed coffee is generally "caffeine-free" coffee.
Coffee is one of the three largest soft drinks in the world, and it is the second largest trading product after the oil in the world. Its popularity is evident. And the coffee culture contained in its packaging is also charming due to its long-term accumulation.
