Requirements of coffee bean packaging

In order to keep the freshness of coffee beans to the utmost, We should take some important things into consideration, such as keeping the good flavor, letting the gas out and keeping the oxygen out.

  • Keeping the good flavor

First of all, the main way to keep the good flavor is to apply the suitable packaging material that won’t get easy permeation for these molecules through the bags.
Typically, metal cans or laminated packaging materials is pretty suitable. Therefore, we suggest the packing material, such as the premade pouch or roll film has include the laminate material.

  • Letting the gas out

After the coffee beans roasted, the beans will release very large volumes of C02. If packing in regular bag which is impermeable to C02, the pressure will become really high if that gas can’t go out, and lead to bag blow up.
Therefore, we suggest to pack the coffee bean with one-way valve which could leave the gas out. At the same time, the one-way valve could ensure that the air can’t enter in bag.

  • Keeping the oxygen out

With the oxidation reaction, due to the fat in coffee beans, which will go stale with the oxidation reaction. It also contains a lot of flavor molecules that could all react with oxygen. With the oxygen, the reactions will deteriorate the coffee quality.

Before packing, we will flush the bag with Nitrogen, to reduce the air in the bag, then fill the beans, vacuum and flush with Nitrogen again to minimize the air in bag.
After packing, with the one-way valve which keeping air out, the shelf life and quality of the coffee beans will stay well and longer.
