They are easily affected by light temperature, oxygen and moisture, which is the reason for the deterioration.
According to the above factors, the package materials of ground coffee must meet the requirements of moisture-proof, oxygen insulation and gas barrier. Because of the grinding extent, the coarse ground coffee is a little bit sharp, the package material should be wear-resistant.
You could choose bags with laminate heat sealable materials with a layer of aluminum foiled film. Meanwhile, when packing coffee, vacuuming and nitrogen flushing can be selected as part of the packaging process to reduce oxygen residue.

Bag packing is popular with customers and manufacturers for its attractive shape.
The normal packing pouch formats are flat pouch, quad sealed pouch, stand-up pouch and gusset pouch.
