PVDC Latex
The Key to Reliable Quality in Packaging Solutions
What is PVDC Latex?
PVDC Latex is an aqueous emulsion primarily made from polyvinylidene chloride (PVDC). It offers outstanding water vapor and oxygen barrier properties when applied as a coating to films or other substrates. PVDC-coated films are widely used across various industries.
Unlike other barrier materials that typically protect against either water vapor or oxygen, PVDC Latex provides a dual barrier, making it ideal for applications requiring moisture and oxygen protection. This quality makes it particularly valuable in pharmaceutical and food packaging, where it helps extend product shelf life and maintain quality.

Properties of PVDC Latex
01
High Barrier Properties
For pharmaceutical packaging, barrier protection is critical to maintaining product integrity. Our PVDC Latex offers exceptional resistance to both water vapor and oxygen, helping to support long-term product stability.
Water Vapor Barrier
Helps protect moisture-sensitive products like tablets and capsules from degrading, maintaining efficacy.
Oxygen Barrier
Reduces oxidation, potentially extending the shelf life of active ingredients and assisting in keeping products effective.
02
Transparency
Clear packaging enhances product visibility and consumer appeal. PVDC Latex can be applied at optimal thickness to achieve high transparency, even when coated on materials like PVC. This allows for attractive packaging designs that showcase the product while offering protection.
03
Impact Resistance
Blister packaging must withstand external impacts without losing integrity over time. Our specially formulated PVDC Latex optimizes the crystallization rate, preventing brittleness and maintaining impact resistance longer than conventional PVDC-coated sheets used in food packaging.
04
Heat Sealability
The blister packaging process involves inserting solid preparations and heat-sealing them with composite films such as aluminum foil to create blister sheets. At this stage, the PVDC barrier layer is also required to have heat sealability. Our PVDC Latex has been widely adopted by many customers who have heat sealability requirements. Please feel free to contact us for more details.
05
Oil and Chemical Resistance
Our PVDC Latex forms a continuous film that offers excellent resistance to oils, acids, and organic solvents. This makes it ideal for coating various substrates, enhancing their durability and protection against environmental and chemical exposure.
Oil Resistance
Chemical Resistance
Verified Chemical Resistance with the Following Agents
- Acetone
- Ethanol
- Hydrochloric Acid
- 30% NaOH Aqueous Solution
* Room Temperature Immersion Test (JASO M312-85) Standard
Additional Properties
Fragrance Retention
Maintaining fragrance is important for both food and nutraceutical products. PVDC Latex-coated films effectively preserve beneficial aromas while blocking external odors, helping to maintain the therapeutic effects and aromatic qualities of the packaged products.
Odor Transmission Reduced to Less Than 1/10,000
Flame Retardancy
Since it's a chlorine-based material, PVDC Latex offers flame-retardant properties, reducing the risk of ignition. This makes it a valuable choice for applications where safety is critical, such as automotive and construction materials.
FAQ
PVDC Latex is an aqueous emulsion made from vinylidene chloride (VDC) and other monomers. It is used as a high-barrier coating for packaging films.
Key applications include:
・Pharmaceutical packaging (blister packs)
・Food packaging (hams, pastries, coffee, etc.)
・Scented products (cigarettes, air fresheners)
・Coatings for construction materials (to enhance durability and resistance)
・Automotive parts (protective coatings)
・Paper packaging (to enhance barrier properties, moisture resistance, and overall durability)
It forms an effective barrier against water vapor and oxygen, protecting the contents from moisture and oxidation.
Common films include oriented polypropylene (OPP), polyethylene terephthalate (PET), nylon (Ny), and polyvinyl chloride (PVC).
PVDC Latex is generally applied using air knife or gravure coating processes.
Yes, but to ensure good adhesion, films should first undergo surface preparation with corona treatment and anchor coating.
Aging the coat at around 40℃ for 48 hours promotes optimal crystallization and enhances barrier performance.
PVDC Latex is used for heat-sealing applications of automotive parts, coating papers for moisture resistance, and rust prevention on metals.
It is shipped in 1,200-kg Intermediate Bulk Containers (IBCs).
Resin
PVDC Resin
Solvent-Based PVDC Barrier Coating
PVDC Resin is a thermoplastic white powder primarily composed of PVDC. When dissolved in a solvent, it provides high barrier properties similar to PVDC Latex but with a thinner application. This makes it a highly efficient solution for creating high-performance coatings with less material.
Commitment to Quality and Reliable Supply
We maintain strict quality control throughout all processes and adhere to established standards. Our commitment to continuous improvement is supported by our ISO9001 certification, ensuring consistent, high-quality supply.
Sustainability Practices
At Asahi Kasei, we prioritize sustainability by offering solutions that protect products while reducing environmental impact.
