The main functions of PVC film for capsule blister packaging include moisture-proof, dust-proof, light-proof and protection of the integrity of drugs. PVC film plays a key role in blister packaging, ensuring that drugs are not damp, dust-proof, and light-proof during the validity period, and are convenient to carry and use.
In addition, PVC film also has the following specific functions:
Moisture-proof performance: Through high barrier layer lamination and coating treatment, PVC film can effectively prevent moisture from entering the packaging and maintain a dry environment for drugs.
Chemical stability: PVC film has good chemical stability and will not react with drugs, blood, body fluids, etc., ensuring the safety and effectiveness of drugs.
Transparency and gloss: PVC film has high transparency and good surface gloss, which makes it easy for consumers to clearly see the appearance and logo of drugs.
Antibacterial performance: Antibacterial plastics can reduce the risk of infection and further ensure the hygiene and safety of drugs.
These functions together ensure the effectiveness and reliability of PVC film in capsule blister packaging.
