How to distinguish between aluminum foil bags and aluminum-plated bags

First, you need to use the method of viewing to check whether the surface brightness of the aluminum foil bag is dull, because in many professional fields, the brightness of the surface of this aluminum foil bag is far less bright and reflective than that of the aluminum-plated bag. The function is not as good as that of aluminized film products. Observe the whole of aluminum plated bag. If the production process is good, people can be photographed. But here we need to pay attention to the exclusion of matte film aluminum plating.

Under normal circumstances, the feel of the aluminum foil bag itself is relatively thick, and it has a certain crisp and hard feel. After holding it up by hand, we can still feel that it is obviously much heavier than the ordinary ordinary packaging bag. The texture of the aluminum-plated bag is much lighter than that of the aluminum foil bag, and the texture is soft.

Twisting method, usually after twisting and twisting of the aluminum foil bag in the later stage of production, it will produce more obvious coalescence, and it is not easy to rebound, and its aluminum layer will also appear a lot of broken lines; After twisting, there will be no twisting, and it will bounce quickly, and there are no obvious cracks on the surface of the bag.

Using the fire method, in the fire of the aluminum foil bag, we found that the fire point is not easy to burn, and the aluminum layer will rewind due to heat. After burning, it will also be due to related factors such as the aluminum foil itself. , Leaving some gray aluminum dross.
