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 and equipment, chemical raw materials, and pharmaceutical intermediates. Most use three or four layers structure, with good water and oxygen barrier function.
There are no restrictions on the type of aluminum foil bag. It can be customized according to different specifications and styles. It can be made into flat bags, three-dimensional bags, accordion bags, zipper bags and other styles.
Aluminum foil bags are divided into pure aluminum bags and aluminum-plated bags. So how to distinguish between aluminum-plated bags and pure aluminum bags in daily life? In summary, there are the following points:
1. In terms of materials, pure aluminum bags are pure aluminum with high purity and are soft materials; aluminum-plated bags are mixed with composite materials and are brittle materials.
2. In terms of cost, the price of pure aluminum bags is higher than that of aluminized bags.
3. In terms of performance, pure aluminum bags have better moisture-proof and cooling effects than aluminum-plated bags, pure aluminum bags are completely protected from light, and aluminum-plated bags have a light-shielding effect.
Fifth, from the perspective of light transmission, the bag is facing the light or the sun, and the light that can see through the bag is the aluminum-plated bag, and the invisible is the pure aluminum bag.
