Why Choose Polyvinylidene Chloride Emulsion (PVDC Latex) Over Traditional Barrier Materials?
In today’s global packaging and coating industry, manufacturers face increasing pressure to deliver longer shelf life, stronger moisture barriers, and safer food-contact materials while maintaining sustainability and production efficiency.
Traditional materials such as EVOH coatings, wax emulsions, PE extrusion coatings, and solvent-based barrier resins often struggle to balance barrier performance, processing flexibility, and environmental compliance.
Polyvinylidene Chloride Emulsion (PVDC Emulsion / PVDC Latex) has emerged as a high-performance solution widely adopted in food packaging, pharmaceutical blister packaging, coated films, paper barrier coatings, and industrial barrier layers.
PVDC Emulsion vs Traditional Barrier Materials
| Property | PVDC Emulsion | EVOH | Wax Emulsion | PE Extrusion Coating |
|---|---|---|---|---|
| Oxygen Barrier | Excellent | Excellent | Poor | Moderate |
| Moisture Barrier | Excellent | Weak in humidity | Moderate | Good |
| Aroma Barrier | Excellent | Moderate | Poor | Moderate |
| Processing | Water-based coating | Co-extrusion | Coating | Extrusion |
| Environmental Impact | Low VOC | Moderate | Low | High energy consumption |
| Shelf Life Protection | Outstanding | Good | Limited | Moderate |
Key Advantages of PVDC Emulsion
Superior Oxygen Barrier
PVDC provides one of the lowest oxygen transmission rates (OTR) among commercial packaging materials, helping extend product shelf life.
Excellent Moisture Barrier
Unlike EVOH, PVDC maintains stable barrier performance even in high humidity environments.
Water-Based and Environmentally Friendly
PVDC emulsion coatings are water-based, reducing VOC emissions and helping converters comply with environmental regulations.
Flexible Processing
PVDC emulsions can be applied using gravure coating, reverse roll coating, and curtain coating, making them compatible with existing packaging production lines.
Strong Adhesion
PVDC coatings bond well with substrates such as:
- PET film
- BOPP film
- PVC film
- Paper and paperboard
- Aluminum foil laminates
