Alu alu foil raw material

8011, 8021 and 8079 aluminum foil are usually used as alu alu foil raw material for pharmaceutical packaging. When 8011O aluminum foil is used as a pharmaceutical packaging material, the aluminum foil is non-toxic, odorless, has excellent electrical conductivity and light-shielding properties, and has extremely high moisture resistance, gas barrier properties and taste retention, which can most effectively protect the packaging. Haomei Aluminum has strictly controlled the structure, performance, plate shape, thickness difference and surface quality of the aluminum foil produced to ensure the excellent quality of the finished product.

Cold-formed alu alu foil is a sealed package after deep-drawing and pressing. Therefore, it has strong mechanical properties, high antibacterial performance, strong puncture resistance and tear resistance; excellent moisture resistance, shading and extremely high barrier capacity; clean surface, uniform color, no splotches, no oil, smooth and no pinholes; bacteria, mold and other tests, heavy metals do not exceed 0.25% per million, strictly implement industry standards to ensure safety and health.

Nowadays, cold-formed alu alu foil is mostly used for some high-end medicines, and cold-formed medical aluminium foil is generally 8021 aluminum foil. The quality requirements of the pharmaceutical aluminium foil are high, the version is flat, the layout is free of scratches, black oil spots, color difference, roll printing bumps, etc., and no pinholes. If you want to get high-quality aluminum foil surface and dark surface, the roughness of its work roll surface has an important influence on it and must be strictly controlled.

The single-roll roughness uniformity and the mating roll roughness of the used work rolls are controlled within 0.01μm; the paired diameter difference of the finishing roll diameters is static within 0.01mm; at the same time, the double oil uses low flash point, low viscosity base oil, its It is more volatile, and the oil film formed between the two layers of alu alu foil raw material aluminum foil is thinner and more uniform. At this time, the lubricating performance is low, which increases the friction between the two aluminum foils, and prevents relative sliding between the two aluminum foils, and makes the dark surface more uniform in color, does not produce bright spots, and does not produce color difference on the surface.
