According to the test report, our aluminium foil meets the requirements of the US Food and Drug Administration for direct contact with food packaging materials. The total content of lead, cadmium, mercury and hexavalent chromium in our aluminium foil complies with EU Council Directive 94/62/EC.

The aluminium foil can be divided into a light aluminium foil and a double-sided aluminium foil according to the surface state。

One-side light aluminium foil: Double-rolled aluminium foil, which is bright after being rolled up, and the surface is black, and such aluminium foil is called a light aluminium foil. The thickness of one side of the aluminium foil usually does not exceed 0.025 mm.
two-sided aluminium foil: single-rolled aluminium foil, two paintings and roll contact, the two sides of the aluminium foil are divided into mirror surface, two-sided aluminium foil, ordinary two-sided aluminium foil due to the different surface roughness of the roll. The thickness of the two-sided aluminium foil is generally not less than 0.01 mm.
aluminium foil can be divided into plain foil, embossed foil, composite foil, coated foil, colored aluminium foil and printed aluminium foil according to the processing state.
