It is widely used in the trademarks and Package.Aluminum foil bags are made of aluminum and other high-barrier materials after dry compounding. Aluminum foil bag has the characteristics of light weight and luster, strong reverse ability, good barrier property, airtightness and moisture, strong temperature adaptability, stable shape at high temperature or low temperature, strong shading, and excellent moisture resistance. It has the functions of moisture resistance, barrier, light protection, permeability resistance and beautiful appearance, and the water vapor transmission rate can reach<0.015 g/(m2·24h)>.The aluminum foil bag has metallic luster, good light-proof, and high reflective ability to heat and light. The metallic luster and reflective ability can improve the brightness of printed colors;Good isolation, strong protection, impermeable to air and water vapor, prevent moisture absorption and vaporization of the contents, and not easy to be invaded by bacteria and insects;Good shape stability and unaffected by humidity changes.
