February 28,2022

Coffee is a drink that most young people like now. In addition to Starbucks and other cafes, in fact, DIY at home is also a good life choice. Of course, the variety and origin of coffee beans are very important and directly determine the taste of coffee, but the packaging cannot be ignored. After all, tide coffee beans are not that tasty.


If the coffee packaging bags are made of a material with low gas barrier, even if it is tightly sealed, the aroma of the coffee will permeate. Also, oxygen, water vapor, and various other gases in the air penetrate into it. So what kind of bag is suitable for coffee packaging?

Four common types of coffee packaging bags


1️⃣Non-airtight coffee packaging: This is the most economical packaging and usually used by small local bakeries because they can guarantee quick supply. This type of packaging, also called air-packing, is filled with air, but the disadvantage is that coffee beans can only be kept for a short time in this type of bag.


Of course, this kind of packaging can simply isolate the effects of moisture, flavor loss and light on coffee beans, but due to long-term contact with the air in the bag or container, the coffee beans inside are seriously oxidized, making their taste period shorter.


2️⃣Air-tight packaging: Air-tight packaging is to vacuum and seal the coffee after being filled. Due to the formation of carbon dioxide during the roasting process, this package can only be packaged after the coffee has been left for a period to deaerate, thus having a storage interval of several days. Coffee beans last longer than ground coffee. Low cost as no separation from air is required during storage. Coffee in this packaging should be used up within 10 weeks.


3️⃣Vacuum packaging: There are two conditions for the production of vacuum packaging: 1. Vacuuming. 2. A flexible and soft material. Of course, this technology can also be applied to some hard materials, but it is usually common to use some soft materials to make it a hard product like a "brick".


This packaging method will make the coffee and the packaging material closely fit together, that is to say, the coffee beans that are completely exhausted, otherwise the tightness of the entire packaging will be reduced and become soft and swollen.


4️⃣Pressurized packaging: This is the most expensive method, but it can keep the coffee for up to two years. After a few minutes of roasting, the coffee can be vacuum-packed. After adding some inert gas, keep the right pressure inside the package. The coffee beans are kept under pressure, allowing the aroma to flow onto the fat, thereby improving the aroma of the beverage.


Such packaging is usually used on water-cooled coffee beans, which have a shorter shelf life and a worse flavor. If the container is packed with hard materials, after vacuuming, due to the pressure difference between the coffee beans and the tank, the gas released by the coffee beans will make the whole environment saturated, thereby inhibiting the volatilization of aroma.
