Introduction

Polyvinylidene chloride (PVDC) is a versatile and widely used polymer in the pharmaceutical packaging industry. Known for its exceptional barrier properties, PVDC plays a crucial role in safeguarding pharmaceutical products against moisture, oxygen, and other environmental factors.

What is PVDC?

PVDC is a synthetic polymer belonging to the vinyl polymer family. It is primarily composed of polymerized vinylidene chloride monomers. The molecular structure of PVDC gives it outstanding barrier properties, making it highly effective in preventing the permeation of gases and water vapor.

Applications in Pharmaceutical Packaging

In the pharmaceutical industry, PVDC is extensively used to coat various packaging materials, including blister packs, sachets, and bottles. The coating enhances the protective features of these materials, ensuring the stability and efficacy of the pharmaceutical products contained within.

• Blister Packs: PVDC-coated blister packs are utilized for packaging tablets and capsules, providing an effective barrier against moisture and oxygen.
• Sachets: Sachets lined with PVDC coatings are ideal for packaging powders and granules, maintaining the integrity of the active ingredients.
• Bottle Linings: PVDC is applied as a lining within bottles to offer an additional layer of protection for liquids and suspensions.

Advantages of PVDC

PVDC excels in pharmaceutical packaging due to its high barrier properties and versatility. Key advantages include:

• Moisture Barrier: With a moisture vapor transmission rate (MVTR) as low as 0.5 g/m²/day at 38°C and 90% RH, PVDC significantly extends the shelf life of moisture-sensitive pharmaceuticals.
• Oxygen Barrier: An oxygen transmission rate (OTR) of 2-5 cc/m²/day makes PVDC an excellent choice for protecting against oxidation and degradation.
• Thermal Stability: PVDC retains its barrier properties over a wide range of temperatures, making it suitable for diverse storage and transport conditions.
