Coffee bags are packaging products for storing coffee.
Roasted coffee bean packaging is the most diverse form of coffee packaging. Because coffee beans will naturally produce carbon dioxide after roasting, direct packaging is easy to cause damage to the packaging, and prolonged exposure to air will cause aroma loss and lead to oil and aroma in coffee. Oxidation of components causes quality degradation. Therefore, the packaging of coffee beans (powder) is particularly important.
Packaging Category
There are many types of coffee packaging and various materials. Don't think that coffee packaging is the colorful little bags you usually see. 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 coffee supply form, coffee packaging can be basically divided into three categories, green bean export packaging, roasted coffee bean (powder) packaging, and instant coffee packaging.
Green bean export packaging
Raw beans are generally packaged 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 lbs). In addition to the name of the country and its coffee organization, coffee production unit, and production area, the coffee sacks will also print the most typical patterns of their own country on the sack. These seemingly ordinary commodity sacks, in the eyes of coffee fans , has become a footnote to interpret the cultural background of coffee. It has even become a collection of many coffee fans. This kind of packaging can be called the original packaging of coffee.
Roasted coffee beans packaging
Generally divided into bags and cans.
(1).Bag:
Bags are generally divided into: non-airtight packaging, vacuum packaging, one-way valve packaging, pressurized packaging.
Non-airtight packaging:
In fact, it is a kind of temporary packaging, which is only used for short-term storage.
Vacuum packing:
The roasted coffee beans need to be stored for a period of time before packaging 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 on the packaging bag allows the carbon dioxide produced to be discharged but prevents the entry of external air, ensuring that the coffee beans are not oxidized but cannot prevent the loss of aroma. These packages can be stored for up to 6 months. There are also some coffees that are packaged with vent holes, that is, only vent holes are made on the packaging bag without installing a one-way valve, so that once the carbon dioxide produced by the coffee beans is emptied, the outside air will enter the bag and cause oxidation, so its storage Time is greatly reduced.
Pressurized packaging:
After the coffee beans are roasted, they are vacuum-packed and then filled with inert gas to seal. This type of packaging can ensure that the coffee beans will not be oxidized, the aroma will not be lost, and the strength is sufficient to ensure that the packaging will not be damaged by air pressure. It can be stored for up to two years.
(2). Canned:
Cans are generally metal and glass, and are equipped with plastic lids for easy airtightness.
instant coffee packaging
The packaging of instant coffee is relatively simple. Generally, small sealed packaging bags are used, mainly in long strips, and an outer packaging box is also available. Of course, there are also some canned instant coffee supplies on the market.
