No Residues: The inside and outside of the aluminum foil food container should not have residual stamping oil (or engine oil), avoiding a sticky (wet) feeling; aluminum shavings and waste should not stick to the surface of the aluminum foil food container; the surface of the aluminum foil food container should not have obvious handprints and scratches; the surface of the aluminum foil food container should not have dust.
Intact Appearance: The rolled edge should not have missing material, mixed material, depressions, or a feeling of scratching the hand; the four corners of the high-edge products should be the same height (the same as the straight edge height), and no material should be missing; the folded edge products should have folded edges that are regular (no missing material), and the aluminum foil food container should be attached; the high-edge products should ensure that the high edge is regular, perpendicular to the aluminum foil food container, and there is no compression phenomenon.
