Roasted coffee beans (powder) packaging is the most common form of coffee packaging. Since coffee beans naturally produce carbon dioxide after baking, direct packaging can easily cause damage to the packaging. Prolonged exposure to air can cause loss of aroma and lead to fat and aroma in coffee. The oxidation of the ingredients causes a decrease in quality. Therefore, the packaging of coffee beans (powder) is particularly important.
Flat bottom ziplock bag for coffee is available in a wide variety of materials. Don't think that coffee packaging is the kind of colorful little bags that you usually have. In fact, the world of coffee packaging is very exciting. According to the form of coffee supply , flat bottom paper bags for coffee can be divided into three categories: raw bean export packaging, roasted coffee bean (powder) packaging, and instant coffee packaging.
Raw bean packaging generally uses sacks. Different coffee producing countries in the world usually use sacks of 70 kg or 69 kg (only Hawaiian coffee is packed in 100 lbs) when exporting coffee beans. On the coffee sack, in addition to the name of the country and its coffee organization, coffee production unit, and production area, it will also print the most typical pattern of its own country on the sack. These seemingly ordinary commodity sacks, in the eyes of coffee fans It has become a footnote to interpret the background of coffee culture. It has even become a collection of many coffee fans, and this type of packaging is the initial packaging of coffee.
Coffee packaging bags are generally divided into: non-hermetic packaging, vacuum packaging, one-way valve packaging, pressurized packaging. Non-hermetic packaging is actually a temporary package that is only used for short-term storage. Vacuum packaging requires placing the roasted coffee beans for a period of time to be packaged to prevent damage to the packaging by carbon dioxide. Such packaging can generally be stored for about 10 weeks. The check valve package is a check valve that adds a check valve to allow the carbon dioxide to be removed, but blocks the entry of outside air, ensuring that the coffee beans are not oxidized but do not prevent the loss of aroma. This type of package can be stored for up to 6 months. Some coffees are also vented in the venting hole, that is, only the venting holes are made in the packaging bag without the check valve, so that once the carbon dioxide generated by the coffee beans is emptied, the outside air will enter the bag, causing oxidation, so its storage Time is greatly reduced. The pressurized packaging is that the coffee beans are quickly packaged in a vacuum and then filled with an inert gas seal. This type of packaging ensures that the coffee beans are not oxidized while ensuring that the aroma is not lost and that there is sufficient strength to ensure that the package is not damaged by air pressure. Can be stored for up to two years.
Instant flat bottom coffee bag is relatively simple, usually in a small sealed bag, mainly in long strips, and an outer box. Of course, some of the canned instant coffee supplies are also available on the market.
Different types of coffee packaging bags are not the same material. Generally, the raw bean export packaging material is simple and plain. There is no special material requirement for instant coffee packaging, basically using general food packaging materials. Coffee bean (powder) packaging generally uses opaque plastic composite materials and environmentally friendly kraft composite materials due to the requirements of oxidation prevention.
Packaging is a brand-faced "face". Many coffee brands seek breakthroughs in tradition, and grasp the connection between taste buds and emotions through creative design, and do some articles in this regard. Or simple and trendy, or traditional retro, each package conveys its own coffee culture and brand personality. Many people buy coffee because of coffee packaging bags, so be sure to look good in coffee bags.
