Roasted coffee beans (powder) packaging is the most diverse form of coffee packaging. Because coffee beans naturally produce carbon dioxide after roasting, direct packaging is easy to cause packaging damage and long-term exposure to air can cause aroma loss and lead to oil and aroma in coffee Oxidation of ingredients causes quality degradation. Therefore, the packaging of coffee beans (powder) is particularly important.
There are many types of coffee packaging and various materials. Don't think that coffee packaging is the kind of colorful bags you usually have. In fact, the world of coffee packaging is very exciting. The following is a brief introduction to the knowledge of coffee packaging.
According to the form of coffee supply, coffee packaging can be divided into three categories: export packaging of raw beans, packaging of roasted coffee beans (powder), and packaging of instant coffee.

Raw bean export packaging
Raw beans are usually packed in sacks. When exporting coffee beans, different coffee producing countries in the world usually use sacks of 70 kg or 69 kg (only Hawaiian coffee is packaged in 100 pounds). In addition to the names of the country and its coffee organizations, coffee production units, and production areas, coffee sacks will also print the most typical patterns of their own countries on sacks. These seemingly ordinary commodity sacks appear to coffee fans , Has become a footnote to interpret the coffee culture background. It has even become a collectible item for many coffee fans. This type of packaging is called the original packaging of coffee.
Roasted coffee beans (powder) packaging.
Generally divided into bags and cans
Bags are generally divided into: non-hermetic packaging, vacuum packaging, one-way valve packaging, and pressurized packaging.
It is actually a temporary package and is only used for short-term storage.
It is necessary to store the roasted coffee beans for a period of time before packaging to prevent carbon dioxide damage to 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 block the entry of external air, ensuring that the coffee beans are not oxidized but cannot prevent the loss of aroma. Such packaging can be stored for up to 6 months. Some coffees are packaged with vent holes, that is, only vent holes are made in the bag without a check valve, so that once the carbon dioxide generated by the coffee beans is emptied, the outside air will enter the bag and cause oxidation, so its storage Time is greatly reduced.
After roasting, the coffee beans are quickly vacuum-packed and filled with an inert gas seal. This type of packaging can ensure that the coffee beans are not oxidized and the aroma will not be lost. There is enough strength to ensure that the packaging will not be damaged by air pressure and can be stored for up to Two years.
Cans are generally made of metal and glass, and are equipped with plastic lids for easy sealing.
Instant coffee packaging
Instant coffee packaging is relatively simple, generally using small sealed bags, mainly in long strips, and there are also outer packaging boxes. Of course, there are some instant coffee supplies in cans on the market.
Different types of coffee packaging have different materials, and the general raw bean export packaging material is relatively simple, which is the ordinary sack material. 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 requirements such as anti-oxidation.
The color of coffee packaging also has certain rules. According to the conventions formed in the industry, the color of finished coffee packaging reflects the characteristics of coffee to a certain extent:
The red-packed coffee generally has a thicker flavor, which allows the drinker to quickly wake up from the good dreams of last night;
Black-packaged coffee belongs to high-quality small fruit coffee;
Coffee in golden packaging symbolizes wealth, indicating that it is the best in coffee;
Coffee in blue packaging is generally "decaffeinated" coffee.
Coffee is one of the world's three largest soft drinks and the world's second largest trading product after oil. Its popularity is evident. The coffee culture contained in its packaging is also fascinating due to long-term accumulation.
