Details

The raw material used for the production of PTP aluminum foil(https://www.aluminumsheet-manufacturer.com) by pharma aluminum foil printing is pure aluminum foil for industrial use. Generally, the thickness is 0.02mm, the tensile strength is 98kPa, the breaking strength is 90kPa, the surface is clean, flat, no wrinkles, no indentation damage, no filming. Fluorescent substance, surface wetting tension is not less than 32. The requirement for the pinhole of the pharma aluminum foil is that the pinhole having a diameter of 0.1-0.3 mm is not more than 1/m2. Because the pinhole of the pharma aluminum foil is a penetrating defect, the drug is degraded or deteriorated by the intrusion of oxygen, water vapor and light, so the requirement for pinhole is very strict; When the required deviation (10%) is applied, it will affect the coating amount of the adhesive layer and the protective layer, and it is necessary to attract the attention of the operator.
