Aluminum foil bag The aluminum foil bag is beautiful and elegant, and its advantages are light-proof, moisture-proof and oxygen-resistant. Aluminum foil laminated bags are generally treated with vacuum, nitrogen filling or deoxidizer, and then matched with packaging cartons or synthetic paper cans, which is conducive to the storage of tea leaves.

Nitrogen-filled packaging will swell the packaging and must not be squeezed to avoid bursting. Whether it is nitrogen filling or vacuum packaging, it is necessary to add outer packaging for preservation, which is more expensive.
