The function of food-grade aluminium foil material

As we all know, food grade aluminium foil bag is a kind of high quality packaging bag, printed aluminium foil bag is magnificent, not only improves the grade of the aluminium foil bag packaging products, but also improves the display value of the aluminium foil bag packaging products, widely used in the trademark and packaging of good products.

Aluminium foil pouches are made by dry mixing aluminium and other high barrier materials. Aluminium has the characteristics of light weight, glossy, strong reverse ability, good barrier, impermeable, impermeable to water, temperature adaptability, stable shape at high or low temperature, strong light shading and excellent moisture resistance. Therefore, the aluminium foil pack has good moisture resistance, barrier, light avoidance and impermeability, beautiful appearance and water vapour transmission rate up to 0.015 g/(m224h) or less.

The aluminium foil bag has a metallic lustre, good light resistance and strong reflective ability to heat and light, the metallic lustre and reflective ability can improve the brightness of the printed colour; good heat insulation, strong protection, impermeable to gas and water vapour, prevent the contents from absorbing moisture and vapourisation, not easily attacked by bacteria and insects; good shape stability, not affected by changes in humidity. Composite aluminium foil bags also have the advantage of heat preservation. Food grade aluminium foil packaging bags are widely used in food and medical packaging, generally for packaging meat products, dried fish, aquatic products, bacon, roast duck, roast chicken, roast pork, frozen food, ham, bacon products, sausages, cooked meat products, kimchi, soy sauce, seasonings, etc.
