In the current market, many merchants will use aluminum-plated bags and aluminum-foil bags. Their appearance is basically the same, but their functions and appearances are different. The following will introduce the common differences between aluminum-foil bags and aluminum-plated bags. What?
Aluminized bags are coated with high-purity metal aluminum on plastic films in a high-temperature vacuum state. Because of the coating, the role that metal aluminum can bring to plastic bags is actually a decorative effect. Not much effect.
The aluminum foil bag is made of pure metal aluminum sheet, and its 0.0065MM is the thinnest thickness. The aluminum foil film that has not been processed by other processes will be damaged by gently poking it with your fingers. Although the aluminum foil film looks “weak”, it is Compared with other composite materials, the effect of the material is extremely powerful. After compounding, it can improve the sealing, barrier properties, fragrance retention, concealment and other functions of plastics.
The difference in appearance is because the brightness of the aluminum foil bag is not as bright as that of aluminized, so the reflectivity of the aluminum foil bag is not as good as that of the aluminized film. If you need to distinguish, you can block the mouth of the bag and see the inside of the bag through strong light. The light-transmitting bag is the aluminum-plated bag, and the opposite is the aluminum foil bag.
The difference in feel is that the aluminum-plated bag is lighter and softer than the aluminum foil bag.
Folding, the aluminum foil bag is prone to dead folds and dead marks after folding, but the aluminum-plated bag will not have this effect, and it will bounce back quickly after being folded.
