Aluminized bagPure aluminum bagWhat is Aluminized Packaging Bag? That is, it refers to the packaging bag made by machine thinning using the ductility of aluminum. Features of aluminized bags Appearance: opaque, silver-white, reflective, with good barrier properties, heat-sealing properties, light-shielding properties, high temperature resistance, low temperature resistance, oil resistance, fragrance retention;Non-toxic, tasteless, soft and other characteristics.So what is an aluminum foil bag? Aluminum foil bags usually refer to aluminum-plastic composite vacuum packaging bags. Product features of aluminum foil bags Appearance: opaque, silver-white, reflective, with good barrier properties, anti-oxidation, water-proof, moisture-proof; light-shielding, high temperature resistance, low temperature resistance, oil resistance, fragrance retention; environmental protection , non-toxic and tasteless; has good heat sealing, softness and other characteristics.So what is the difference between aluminized bags and pure aluminum bags? From the above characteristics, we can summarize the following points: 1, Aluminized bags and pure aluminum bags have different appearances. From the perspective, we can see that the pure aluminum bag is opaque, while the aluminum-plated bag is facing the light or sunlight, and the light can be seen through the bag. 2, In terms of cost, the material used in pure aluminum bags is pure aluminum, with high purity, and is a soft material; while aluminized bags are mixed with composite materials, which are brittle materials. 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 are shading. 4In terms of use: pure aluminum bags are more suitable for vacuuming, such as cooked food, meat and other products, while aluminum-plated bags are suitable for tea, powder, electronic parts, etc. 5, It can be distinguished by fire: aluminum foil is not easy to burn with fire. The aluminum foil package will leave a gray aluminum slag after burning. When the aluminized film is burned, different plastic films can be burned, and there is no residue of aluminum slag. 6, There are two kinds of packaging bags that can be folded: aluminum foil bags are easy to be folded to produce dead folds and dead marks. And it will bounce back soon. The aluminum layer will break. The kink will pop open soon after the aluminum-coated bag is twisted. 7, You can also twist it with the country. After the aluminum foil bag is twisted, it is not easy to rebound after coalescing. There will be no visible cracks in the aluminum layer. 8, After getting two kinds of bags, you can touch them with your hand. The hand of aluminum foil bag is thick and stiff, harder and heavier, and the hand of aluminum-plated bag is lighter and softer than that of aluminum foil bag.
