How to distinguish the good from the bad?
1, Dark stripe
The dark side stripes mostly appear on the double joint products, and there are obvious strip patterns of light and dark alternating along the rolling direction on the dark surface, which affects the beauty.
2, Aluminum foil bruise
The bruise of aluminum foil refers to the damage on the surface or end face of foil after collision with other objects during handling or storage. Most of the bruises are caused by careless packing of aluminum foil.
When the surface of aluminum foil contacts with the surrounding media, after chemical reaction or electrochemical reaction, the surface of aluminum foil will lose luster, and in serious cases, gray corrosion products will be produced. The corroded aluminum foil has a great influence on the beauty of the products produced by the terminal.
The aluminum foil with surface bubble defects will have irregular round or strip cavity bulges on the surface of the foil; the convex edge is smooth, both sides are asymmetric, and the distribution is irregular, and the surface bubbles make the stress of each point of the aluminum foil strip unbalanced, which is likely to lead to break down.
