Introduction

Blister packs are a common packaging method used primarily in the pharmaceutical industry to protect products from environmental factors and contamination. Two materials frequently used for the production of blister packs are Polyvinyl Chloride (PVC) and Polyvinylidene Chloride (PVDC). Despite their similar applications, PVC and PVDC have distinct differences that influence their selection for specific use cases.

PVC vs. PVDC in Blister Packs

PVC and PVDC are both thermoplastic polymers, but their chemical compositions and properties vary significantly. These variations affect their performance, environmental impact, and suitability for certain applications.

PVC (Polyvinyl Chloride)

• Composition: PVC is made from polymerizing vinyl chloride monomers.
• Barrier Properties: Offers moderate barrier protection against moisture and oxygen.
• Thermal Properties: Melting point ranges from 180°C to 210°C.
• Cost: Generally less expensive compared to PVDC.

PVDC (Polyvinylidene Chloride)

• Composition: PVDC is formed through the polymerization of vinylidene chloride.
• Barrier Properties: Superior barrier against moisture and oxygen, making it suitable for sensitive products.
• Thermal Properties: Melting point ranges from 160°C to 190°C.
• Cost: More expensive due to complex manufacturing processes.

Parameters and Properties

When evaluating PVC and PVDC for blister packs, several parameters must be considered, including their mechanical properties, chemical resistance, and environmental impact. The table below summarizes these properties:
