Coffee packaging bag is a bag used to hold coffee beans, because coffee beans will naturally produce carbon dioxide after roasting, direct packaging is easy to cause packaging damage, and long-term contact with air will cause aroma loss, and lead to the oxidation of the oil and aromatic components in the coffee resulting in quality degradation. Therefore, the packaging of coffee beans (powder) is particularly important, so what kind of garbage classification does the used coffee packaging bag belong to?
What kind of garbage does a used coffee packaging bag belong to
According to the domestic waste classification standard, coffee packaging bags belong to other garbage. Because the used coffee packaging bags have been contaminated, they do not have much recycling value, so they can only be classified into other garbage. Remember to dispose of used coffee bags in gray other garbage containers.
Why are there holes in coffee packaging bags
After roasting, the coffee will continue to emit carbon dioxide for a period of time, and the coffee bag will be filled with gas without a one-way valve and easy to burst, and the one-way air valve can also discharge the oxygen in the packaging bag while discharging carbon dioxide, so as to avoid the odor caused by the oxidation of the coffee oil.
