In fact, the aluminum foil bag is a kind of packaging bag of the composite bag, and is also a kind of composite bag containing aluminum foil. According to the unique property of the aluminum, aluminum and other high barrier materials are dry-composited to form an aluminum foil bag product.
The main film substrates of the composite bag are: outer layer printable film BOPA, BOPET, BOPP, inner layer heat sealable film CPP, PE, and coextruded film. The materials and characteristics of the two are different.
The main storage methods of aluminum foil bags are as follows: the material is solid and the density is high. The best choice is the plastic bag for sealing and for food. Do not use plastic bags that have a taste or remanufacture. The air in the tea bag should be squeezed out as much as possible. If it can be reversed with a second plastic bag, it is better to use sunlight in a plastic bag. The principle of packaging tea in aluminum foil is similar to that of plastic bags.
2. The aluminum foil bag shall be inspected for aluminum foil bags according to national standards during production, and shall be used in accordance with sanitary standards. Aluminum foil bags should be transparent and colorless. Do not use a lot of colors to prevent the color from being thermally decomposed and harmful. To ensure that the foil pouch is shipped with no odor, do a safety check. The foil bag is carried out to keep itself, not to be coated or plated.
Not only that, but also has an other feature that the aluminum foil bag can be coated with anti-static liquid, so that the aluminum foil bag used has an anti-static effect, and can package electronic products, circuit boards, and the like. Moreover, our company's aluminum foil bags can also print various patterns according to customers' requirements. For example, milk powder, health care products, nutritional products, etc. are all packaged in aluminum foil bags. The aluminum foil bag has a metallic luster, has high reflection ability to heat and light, has good insulation performance, strong protection performance, and has the characteristics of non-breathable body and moisture, thereby effectively preventing moisture absorption and gasification of the contents, and is not susceptible to bacteria and bacteria. Insect damage, good shape stability, and not affected by humidity changes.
