PTP aluminum foil

The raw material used in the production of PTP aluminum foil is pure aluminum foil for industrial use, which generally requires a thickness of 0.02 mm, a tensile strength of 98 MPa, and a rupture strength of 90 MPa. The surface of PTP aluminum foil is clean and smooth, without wrinkles, no indentation damage, and no fluorescent substances The surface wetting tension is not less than 32. The requirement for the pinhole size of medicinal aluminum foil is that the pinholes with a diameter of 0.1 ~ 0.3mm are not more than 1 per m2. Since the pinhole in the aluminum foil is a defect of penetration, the intrusion of drugs by oxygen, water vapor and light will reduce the efficacy or deteriorate, so the requirements for the pinhole are very strict; in addition, if the thickness of the aluminum foil exceeds the required deviation ( 10%), it will affect the coating amount of the adhesive layer and the protective layer, so the operator's attention is required for produce PTP aluminum foil.
