Alu Foils With Thickness of 9Mic Alloy 8079
The Alu Foils used in food packaging bags is made of Aluminum Foil Alloy 8079, which has good barrier properties. The oxygen transmission rate of 9 micron aluminum foil is extremely low, which can effectively block the gas in the air that easily deteriorates food, such as oxygen. And the thickness of alu foils is opaque and has good shading properties to prevent some foods from discoloring or deteriorating due to light. The 9 microns aluminum foil is made by rolling. If the rolling property of the 8079 aluminum foil is not good, it is impossible to press the thick aluminum plate into a very thin aluminum foil.
Alu Foils With Thickness of 9Mic Alloy 8079 cannot be used alone, it must be combined with plastic film. Aluminum foil bags are generally composed of four layers of different components, which have good oxygen and water barrier functions, and can be moisture-proof and light-proof, and can also be vacuum-packed. Medicines and milk, etc., because the plastic bag is a single layer, and the moisture barrier and oxygen barrier function are not good, it cannot be used for the packaging of items with high packaging requirements. Aluminum foil can be combined with PE/AL/PE/CPP to make beautiful packaging bags. PE has good printing effect, aluminum foil has strong barrier performance, opaque, PE ordinary packaging inner layer, and CPP high temperature cooking inner layer. When using aluminum foil, the purity of the material is very high, it must reach 99.99%, and there is almost no impurities. However, because of the existence of small pores, aluminum foil is rarely used alone, and must be used together with plastic film. The thickness of the aluminum foil material is generally between 6 microns and 30 microns, and it can be made into different processes according to different uses and the size of the packaged products.
The surface of the aluminum foil bag generally has anti-gloss characteristics, Can aluminum foil be used to wrap food ?Sure .aluminum foil does not absorb light, and is made of multiple layers. Therefore, Alu Foils With Thickness of 9Mic Alloy 8079 not only has good light-shielding properties, but also has strong insulating properties. Very good oil resistance and softness. Compared with plastic bags, aluminum foil bags are not poisonous and have no special smell. It is definitely a green production product, an environmentally friendly product, and an aluminum foil bag that also meets the national hygiene standards.
