PVC vs PVDC Foil: What’s the Difference?

When it comes to packaging materials, PVC and PVDC foils are two of the most commonly used materials. While both are used for packaging purposes, they have some significant differences that make them suitable for different applications.

PVC (Polyvinyl Chloride) foil is a plastic material that is widely used for packaging food, pharmaceuticals, and other consumer goods. It is a cost-effective material that is easy to process and has good barrier properties. PVC foil is commonly used for blister packaging, where it is used to create a protective barrier between the product and the environment. It is also used for shrink wrapping, where it is used to wrap products tightly and protect them from damage during transportation.

PVDC (Polyvinylidene Chloride) foil, on the other hand, is a more advanced material that offers superior barrier properties compared to PVC foil. It is a transparent material that is commonly used for packaging food, pharmaceuticals, and other products that require high barrier properties. PVDC foil is commonly used for packaging products that are sensitive to oxygen, moisture, and other environmental factors. It is also used for vacuum packaging, where it is used to create a tight seal around the product and protect it from external factors.

One of the key differences between PVC and PVDC foil is their barrier properties. While PVC foil offers good barrier properties, PVDC foil offers superior barrier properties, making it more suitable for packaging products that require high levels of protection. Another difference is their transparency. PVC foil is opaque, while PVDC foil is transparent, making it more suitable for packaging products that require visibility.

In conclusion, PVC and PVDC foils are two commonly used packaging materials that have some significant differences. While PVC foil is a cost-effective material that offers good barrier properties, PVDC foil is a more advanced material that offers superior barrier properties and transparency. When choosing between the two, it is important to consider the specific requirements of the product being packaged and choose the material that best meets those requirements.
