Appearance
Thesurface of the pop cans cover coating does not allow defects such as airbubbles, scratches, missing coating, over-burning, oil spots, stains, streaks,color, piebald, roller printing, embossing, periodic prints, chemical liquidetc which impact users.
Each coil allowed a joint which does not allow loose layer or dislocation, thejoint can only be overlapped, which need to make the mark in the end, and eachbatch coil of joint is not more than 10% of the total number of coils.
