An aluminum foil packaging bag is made of aluminum foil, plastic and paper. The shielding property of the aluminum foil is integrated with the strength of the paper and the sealing property of the plastic, which greatly expands the application market of aluminum foil by further improving the foil’s shielding performance of water vapor, air, ultraviolet rays and bacteria that are necessary as packaging materials. Since the packaged article is sufficiently isolated from the outside light, moisture, gas, etc., the package is well protected. Especially for the packaging of retort foods, the use of this composite aluminum foil material can at least guarantee that the food does not deteriorate for more than one year.

　　Aluminum foil bags are not plastic bags, and can even be said to be superior to ordinary plastic bags. Aluminum foil packaging bags are the best choice when you want to refrigerate or pack food now, but also to ensure that the food has the longest shelf life. A common aluminum foil bag, its surface generally has a anti-gloss characteristic, that is, it does not absorb light, and it is made of multiple layers. Therefore, aluminum foil paper has good light-shielding property and strong isolation, and the composition of the aluminum is inside, so it also has good oil resistance and softness.

　　Now, with the constant disclosure of counterfeiting and selling, especially the safety accident of plastic bags, the main concern is not the function of the bag, but its safety. However, consumers can be rest assured that an aluminum foil bag is non-toxic and has no special odor. It is definitely a green raw product, an environmentally friendly product, and an aluminum foil bag that also meets the national health standards. Its scope of application is very wide:

　　(1) Applicable to all kinds of circuit boards, electronic products, precision machinery parts, consumer goods, industrial products and other packaging. For example: PC board, IC integrated circuits, electronic components, SMT patches for various LED industries, light bar packaging, precision hardware, auto parts and other packaging.

　　(2) Food packaging: rice, meat products, dried fish, aquatic products, bacon, roast duck, roast chicken, roast pork, frozen food, ham, cured meat products, sausage, cooked meat products, pickles, bean paste, spices, etc.
