Introduction to PVDC Coating

Polyvinylidene chloride (PVDC) coating is a type of polymer coating widely used in the packaging industry to provide barrier properties to flexible films. It primarily enhances the resistance of packaging materials to moisture, gases, and odors, thus extending the shelf life of perishable products. PVDC coatings are typically applied to substrates like plastic films, paper, and foil.

Applications of PVDC Coating

PVDC coatings are utilized across a diverse range of applications, particularly in the food, pharmaceutical, and cosmetic industries. In the food industry, these coatings are applied to preserve the freshness and quality of packaged food by preventing oxygen and water vapor transmission. The pharmaceutical sector benefits from PVDC through its use in blister packaging, ensuring medication protection against environmental factors. Additionally, cosmetic packaging often employs PVDC coatings to maintain product integrity.

Advantages of PVDC Coating

The primary advantages of PVDC coating include:

• Excellent barrier against moisture and gases.
• High clarity for transparent packaging.
• Enhanced puncture resistance compared to non-coated substrates.
• Compatibility with various substrates, including polyethylene, polypropylene, and PVC.

Technical Specifications of PVDC Coating

PVDC coatings are characterized by specific parameters that influence their performance:

• Water Vapor Transmission Rate (WVTR): PVDC coatings can reduce WVTR to as low as 0.1 g/m²/day at 38°C and 90% relative humidity.
• Oxygen Transmission Rate (OTR): Coatings can achieve OTR values below 0.1 cm³/m²/day under standard conditions.
• Coating Thickness: PVDC coatings typically range from 2 to 5 microns in thickness, depending on application requirements.
