The main raw material of solid pharmaceutical PVC rigid film is polyvinyl chloride (PVC) resin. This packaging material has a smooth and glossy surface, is transparent, and maintains uniform thickness. It features excellent formability, strong compatibility with PTP aluminum foil, and provides good barrier properties against oxygen and water vapor. After thermoforming, the blister is firm and resilient, offering reliable protection and support for the packaged content.
It is primarily used for solid pharmaceutical dosage forms, such as tablets and capsules, but is also suitable for injection trays, oral liquid trays, as well as food and health supplement packaging. PVC rigid film has stable physical properties, reacts poorly with only a few chemical solvents, and generally does not interact negatively with solid substances, ensuring the safety of pharmaceutical and food products.
