Aluminum foil bags are also called pure aluminum bags. Aluminum foil bag packaging usually refers to aluminum-plastic composite vacuum packaging bags. This type of product is suitable for moisture-proof, light-proof and vacuum packaging of large precision machinery, chemical raw materials, and pharmaceutical intermediates. Four-layer structure is mostly used, which has good water and oxygen barrier functions. Without limitation, you can customize packaging bags of different specifications and styles, and can be made into flat bags, three-dimensional bags, organ bags and other styles.
Principle of vacuum bag
The mildew and spoilage of products are mainly caused by the activities of microorganisms, and most microorganisms need oxygen to survive, and the vacuum bag is used to extract the oxygen in the packaging bag and the product cells, so that the microorganisms lose the “survival environment” “To preserve food.
(1) Strong air barrier performance, anti-oxidation, waterproof and moisture-proof.
(2) Strong mechanical properties, high blast resistance, strong puncture and tear resistance.
(3) High temperature resistance (121℃), low temperature resistance (-50℃), oil resistance and good fragrance retention performance.
(4) Non-toxic and tasteless, in line with food and drug packaging hygiene standards.
(5) Good heat-seal performance, flexibility, high barrier performance
The production process of aluminum foil bags is simple and cumbersome. The overall production process is: aluminum ingot smelting- cast rolling- cold rolling- intermediate annealing- - cold rolling- aluminum foil wool material- -rough rolling- middle rolling- fine Rolling (double combination)- slitting- aluminum foil finished annealing-composite-bag making-aluminum foil bag finished product-packaging. In this process, it is the whole process from the aluminum foil wool to the processing of the plain foil, and then in the composite bag making
