Pharmaceutical PVC/PVDC Film

In blister packaging, the combination of PVC and PVDC offers better moisture and gas protection, making it suitable for more sensitive products. This type of blister packaging is commonly used for products that require an extended shelf life and stability.

The combination of PVC (Polyvinyl Chloride) and PVDC (Polyvinylidene Chloride) films in blister packaging provides excellent barrier performance, making it particularly suitable for environment-sensitive products. This combination can significantly extend the shelf life and stability of products, ensuring that contents remain fresh throughout the storage period.

PVC/PVDC Film Aluminium Blister Features

Easy to Form: The film has good formability, adapting to various packaging design requirements.

Fast Sealing Speed: Enhances production efficiency, suitable for large-scale production.

Excellent Barrier Properties: The introduction of PVDC significantly enhances moisture and gas barrier capabilities, protecting the internal product from external environmental influences.

Chemical Resistance: Can withstand various chemicals, making it suitable for packaging a range of pharmaceuticals and nutritional products.

Easy to Process: Compatible with various processing techniques, meeting different customization needs of clients.

Applications of PVC/PVDC Film Aluminium Blister

PVC/PVDC film is primarily used in pharmaceutical packaging, especially for blister packaging of tablets and capsules, ensuring the safety and efficacy of drugs during transportation and storage.

Storage Precautions for PVC/PVDC

• 1. Best storage conditions: 20°C, relative humidity 50%.
• 2. Normal storage conditions: not exceeding 30°C, relative humidity ≤ 70%. During storage, avoid light and moisture; unused PVDC rolls must be packed in black PE bags to prevent discoloration from light exposure.
• 3. Under normal storage conditions, the product retest period is 12 months.
• 4. Handle, transport, and use with care; avoid impacts and drops to prevent breakage.
• 5. If stored at low temperatures, allow the material to sit at room temperature above 18°C for at least 24 hours before use to prevent breakage.
• 6. When using, ensure the PVDC side is heat sealed to the PTP aluminum foil; unless otherwise specified, the PVC/PVDC finished roll has the PVDC side facing inward.
• 7. The heating plate temperature during thermoforming should generally be 2-3°C higher than the same thickness PVC sheet (specific adjustments may be necessary depending on equipment).
• 8. The sealing temperature should be about 5-10°C higher than the same thickness PVC sheet (specific adjustments may be necessary depending on equipment).
• 9. PVC/PVDC has poor surface lubricity and easily sticks to the heating plate and mold of the blister machine, requiring careful maintenance. Regular cleaning of the heating plate with alcohol is recommended, and reapplication of non-stick coatings on worn heating plates. Using Teflon high-temperature adhesive tape on the heating plate surface can also help prevent sticking, and molds should be regularly cleaned with alcohol to prevent stains.
