Coffee bag

Roasted coffee bean (powder) packaging is the most diverse form of coffee packaging. As coffee beans will naturally produce carbon dioxide after baking, direct packaging is easy to cause packaging damage, and long-term exposure to air will cause aroma loss, oxygenation of oil and aromatic components in coffee and quality decline. Therefore, the packaging of coffee beans (powder) is particularly important·

Packaging classification

Coffee packaging has a wide variety of materials. Don't think that coffee packaging is what kind of colorful small bags you usually see. In fact, the world of coffee packaging is very wonderful. Here 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.

Roasted coffee bean (powder) packaging

It is generally divided into bagged and canned.

(1) . bagged:

Bagging is generally divided into: non airtight packaging, vacuum packaging, one-way valve packaging and pressurized packaging.

Non airtight packaging:

In fact, it is a temporary packaging, which is only used for short-term storage.

vacuum packing:

Roasted coffee beans need to be placed for a period of time before packaging to prevent damage to the packaging by carbon dioxide. Such packaging can generally be stored for about 10 weeks.

Check valve packing:

A one-way valve is added on the packaging bag to allow the generated carbon dioxide to be eliminated, but it will block the entry of external gas, so as to ensure that the coffee beans will not be oxidized but can not prevent the loss of aroma. Such packaging can be stored for up to 6 months. Some coffees are packaged with exhaust holes, that is, only exhaust holes are made on the packaging bag without installing a check valve. In this way, once the carbon dioxide generated by coffee beans is drained, the external air will enter the bag and cause oxidation, so its storage time will be greatly reduced.

Pressurized packaging:

The coffee beans will be vacuum packed soon after baking, and then filled with inert gas for sealing. This kind of packaging can ensure that the coffee beans will not be oxidized and the aroma will not be lost. It also has sufficient strength to ensure that the packaging will not be damaged by air pressure and can be stored for up to two years.

(2) . canned:

Cans are generally metal and glass, and are equipped with plastic covers for easy sealing.

Instant coffee packaging

The packaging of instant coffee is relatively simple. Generally, sealed small packaging bags are used, mainly in long strips. In addition, there will be an outer packaging box. Of course, there are also some canned instant coffee on the market.

texture of material

Different kinds of coffee packaging have different materials, and instant coffee packaging has no special material requirements. It basically adopts general food packaging materials. Due to the requirements of anti-oxidation, coffee bean (powder) packaging generally adopts opaque plastic composites and environmentally friendly kraft paper composites.

Coffee is one of the three soft drinks in the world and the second largest trading product in the world after oil. Its popularity can be seen. The coffee culture contained in its packaging is also charming due to its long-term accumulation.
