Wholesale aluminium foil packaging

Short Description:

Coffee aluminum foil packaging bags require strict storage conditions. Generally, non transparent plastic composite materials are used to avoid oxidation. By utilizing the sealing performance of pure aluminum, the original flavor of coffee can be well protected, without losing aroma, being less susceptible to moisture, and avoiding light. Aluminum foil material is colorless, odorless, and non-toxic, and can come into direct contact with food. Therefore, when used for coffee packaging, it also includes cost considerations.

Product Features

Vacuum packaging: The roasted coffee beans need to be left for a period of time before packaging to prevent carbon dioxide damage to the packaging. This type of packaging can generally be stored for about 10 weeks.
One way valve packaging: Adding a one way valve to the packaging bag allows for the elimination of carbon dioxide but blocks the entry of external gases, ensuring that the coffee beans are not oxidized but cannot prevent the loss of aroma. This type of packaging can be stored for up to 6 months. Some coffees are also packaged with exhaust holes, which means that only exhaust holes are drilled on the packaging bag without installing a one-way valve. Once the carbon dioxide produced by the coffee beans is emptied, external air will enter the bag, causing oxidation, thus greatly reducing its storage time.
Pressure packaging: After roasting, coffee beans are quickly vacuum packaged and then filled with inert gas for sealing. This type of packaging ensures that the coffee beans are not oxidized while ensuring that the aroma is not lost, and has sufficient strength to ensure that the packaging is not damaged by air pressure. It can be stored for up to two years.
