Quality Control of Pinholes in Aluminum Foil for Pharmaceutical Packaging

Page view
Pharmaceutical aluminum-plastic blister packaging is widely used in the pharmaceutical industry for its beautiful appearance, good barrier properties, convenience in use, and convenience in carrying. It is the most important packaging for solid dosage forms such as pharmaceutical tablets and capsules. One way.
Aluminum foil for pharmaceutical packaging ( also commonly called PTP aluminum foil ) is one of the two major constituent materials of this packaging method, and its pinhole degree will directly affect the protection of the final packaging to the contents. Because the PTP aluminum foil pinhole is located in the blister area,  which means that the drug is in direct contact with the outside air, the protective function of the drug package will be completely lost,  which brings great risks to the producers and users of the drug. The risks are unacceptable to most drug manufacturers.
PTP aluminum foil pinholes are produced for two reasons: 1 pinholes produced during the production of raw aluminum foil used in the production of PTP aluminum foil; pinholes produced during the production of 2PTP aluminum foil. Since the generation of pinholes in the production process of PTP aluminum foil is relatively easy to control and avoid, the following discussion is mainly directed to pinholes generated during the production of raw material aluminum foil for PTP aluminum foil (hereinafter referred to as raw material aluminum foil).
