Packaging is selected depending on your intended use
You can pack coffee beans in simple paper bags. And this may be perfectly fine for beans that will use within a few weeks, but this is not good if you need to keep the beans fresh for several weeks or months. Therefore, the type of packaging you will choose to use for your coffee beans and ground coffee depends on how long it has been stored, how it has been transported, and the freshness and quality requirements of your desired product!
Requirements for packaging of coffee beans
In order to have the right packaging for coffee beans, there are a few things to keep in mind: preserving the flavor, venting, and allowing oxygen to escape.
Preserve the taste
First of all, the packaging needs to be able to keep the fresh taste of the roasted coffee beans inside the packaging. This means that you will need to use packaging materials that do not allow these molecules to easily seep through the packaging. Usually, metal cans or composite film packaging can be used. These laminated films are made up of several layers of material, usually at least some kind of plastic with a thin metal layer. Although film bags have the characteristic of long shelf life, their main disadvantage is that they are almost impossible to recycle. It is not easy to separate those layers again. Paper bags are not good at keeping the taste. Instead, the gas molecules are free to move in and out of the package.
Exhaust the air
During the roasting process, you are essentially drying the beans. However, the coffee beans do not collapse, instead, the cell walls remain the same structure, while the water inside evaporates. As a result, roasted coffee beans are quite spongy. This porous structure can hold gas quite well during roasting. However, over time, more of these gases will escape. The main gas here is carbon dioxide (CO2). In the first few hours after roasting, coffee beans release a huge amount of carbon dioxide. This gas release is very important, if you pack freshly roasted coffee beans right after roasting in a bag that cannot release carbon dioxide, it can explode and break. The pressure can get really high if that gas can’t get out!
Oxygen is the common enemy of many products. Oxygen is known to participate in oxidation reactions. In the case of fats, these oxidation reactions are what cause the fat to go rancid. Coffee also contains some fat that can go bad. But it also contains a lot of flavor molecules that can react with oxygen. In general, these reactions reduce the quality of the coffee.
By creating packaging that oxygen cannot penetrate, the shelf life and quality of the coffee beans will be better.
There are several other factors that affect the packaging of coffee beans such as humidity, temperature, light, etc.

Packaging considerations for ground coffee
Ground coffee will also be affected in the same way as coffee beans. However, they have one big difference. By grinding the beans, the complex structures inside the coffee beans are broken down. Instead, all internal components are exposed to air. As a result, all the accumulated carbon dioxide (CO2) can escape easily. Instead of waiting days for degassing to happen, for ground coffee beans it’s just a matter of hours or a day. However, it is more susceptible to damage. The flavors can also come out more easily and oxygen can get into the dough without any problems. This is why ground coffee often needs more protection.
