Overview of PVDC in Blister Packaging

Polyvinylidene chloride (PVDC) is a highly versatile thermoplastic used predominantly as a coating material for blister packaging due to its exceptional barrier properties against water vapor, gases, and odors. Its widespread adoption in the pharmaceutical and food industries stems from its ability to extend the shelf life of products by preventing degradation caused by environmental factors.

Properties of PVDC

PVDC is renowned for its outstanding barrier characteristics, which are quantified as follows:

• Water Vapor Transmission Rate (WVTR): PVDC coatings can achieve WVTR as low as 0.1 g/m²/day, making it highly effective in moisture-sensitive applications.
• Oxygen Transmission Rate (OTR): PVDC exhibits OTR values as low as 0.006 cc/m²/day, which is crucial for protecting oxidation-sensitive products.
• Clarity and Flexibility: The material offers transparency and a glossy appearance, enhancing the visual appeal of packaged products while maintaining flexibility over a broad temperature range.

Applications in Blister Packaging

PVDC is predominantly employed in blister packaging for pharmaceuticals, where its barrier properties play a critical role:

• Pharmaceutical Tablets and Capsules: PVDC-coated films provide excellent protection against moisture and oxygen, ensuring the stability and efficacy of medications.
• Food Packaging: In addition to pharmaceuticals, PVDC is used in food packaging, safeguarding perishable items from spoilage and extending their shelf life.
• Unit Dose Medications: With its ability to form airtight seals, PVDC is vital in unit dose packaging, where precise dosage and protection are paramount.
