Aluminum foil coffee bags have excellent barrier properties and can effectively prevent coffee beans from coming into contact with light and air, thereby preventing the aroma of coffee beans from being released and oxidized. This type of packaging bag is usually made of aluminum-plastic composite material, which has good water and oxygen isolation functions and can effectively protect the freshness and quality of coffee beans. It has the following advantages:
(1) With easy-to-tear edge, self-sealing strip design, strong sealing, thickened bottom, and stable standing.
(2) Thickened material, waterproof, moisture-proof, mildew-proof, moisture-proof, prevents odor contamination, and can be used repeatedly.
(3) The bottom is self-supporting, and the internal structure expands and expands when in use. This structure is more stable when self-supporting, and the capacity is greatly increased, making it more three-dimensional.
(4) Thicken the self-sealing strip, use the self-sealing strip to seal, and you can also use the back sealer to seal it again, effectively preventing food from spoiling and getting damp.
