The vacuum aluminum foil bag is made of aluminum and other high barrier materials after dry lamination. Aluminum has the characteristics of light weight, luster, strong reverse ability, good barrier, impermeability and moisture content, strong adaptability to temperature, stable shape at high or low temperatures, strong light shielding, and excellent moisture resistance. Therefore, aluminum foil bags have good functions of moisture resistance, barrier, light shielding, permeability resistance, and beautiful appearance. The water vapor permeability can reach<0.015 g/(m2? 24h)>. They also have the function of heat sealing. They can be vacuum packed. The appearance of composite aluminum foil bags is opaque, It is silvery white and has anti luster, and can be stored in an environment with temperature ≤ 38 ℃ and humidity ≤ 90%. Composite aluminum foil bags are used for food packaging, generally used to package meat products, dried fish, aquatic products, cured meat, roast duck, roast chicken, roast pig, quick-frozen food, ham, bacon products, sausage, cooked meat products, pickles, bean paste, condiments, etc. to preserve the fragrance, quality, taste and color.
