How to distinguish between aluminized and pure aluminum bags
How to identify the material used in aluminum plastic composite flexible packaging is aluminum foil or vacuum aluminized film? Packaging bag sales work, often encounter such a situation. There are many kinds of packaging bags, and many customers can't distinguish aluminum foil bags from aluminum plated bags. In order to let you understand, let's explain the difference between aluminum foil bags and aluminum plated bags
Aluminum coated bag (film) is a high-temperature vacuum state, the high-purity metal aluminum evenly coated on the plastic film. Because it is coated on the plastic, the metal aluminum mainly plays a decorative role, and has no great help to improve the material barrier
Aluminum foil bag (film) is made of pure metal aluminum. The thinnest thickness can reach 0.0065mm. If you poke it with your hand, it will be broken. Although it looks weak without wind, it will play a great role when it is combined with other plastics. After compounding with more than one layer of plastic, the barrier, sealing, fragrance retention and shielding properties of the plastic can be improved, And other functions
1. View: because the brightness of aluminum foil is not as bright as that of aluminum plating, the reflective property of aluminum foil is not as good as that of aluminum plated film. Aluminum coated bag can give out human shadow, except for those with aluminum coating on extinction film. The appearance of aluminum coating on the extinction film is similar to that of aluminum foil. You can block the opening of the bag and look inside the bag through the strong light. The inside of the aluminum foil bag is not transparent, and the transparent one is the aluminized bag.
2. Handle: the handle of aluminum foil bag is thick and straight, hard and heavy, and the handle of aluminum plated bag is lighter and softer than that of aluminum foil bag.
3. Folding: the aluminum foil bag is easy to fold out the dead fold mark. The aluminum plated bag will not fold into the dead fold dead mark, and it will rebound quickly.
4. Twisting: after twisting the aluminum foil bag, the coalescence is not easy to rebound, and the aluminum layer will break. After twisting the aluminum coated bag, the kink will pop up quickly, and the aluminum layer will not have obvious cracks.
5. Burning: the aluminum foil is not easy to burn with the fire point, and the aluminum layer will roll back. After burning, the aluminum foil packaging will leave gray aluminum slag. When the aluminized film is burned, there is no residual aluminum slag.
