Vacuum Packaging Film

Vacuum packaging film uses modified PVA as base material, which is then coated with one of many materials including VMPET, LDPE, and woven fabrics to obtain certain physical or chemical properties to suit the film for diverse uses. Various colors, anti-static agents, and flame retardants can be added to improve the look and performance of our vacuum packaging film upon your request.

The barrier property of our vacuum packaging material mainly comes from the special PVA material which has been modified with nano-scale particles. Modified PVA is water soluble, and has increased bonding strength and a more effective oxygen barrier. Made with food quality material, CVCI vacuum packaging film allows for indirect contact with food.

Below is a list of benefits involved in the use of VPF products.
High Price to Performance Ratio
VPF film products cost little to own. They are generally priced much lower than aluminum composite materials and PVDC coated films.

Ideal Oxygen Barrier
Vacuum packaging film offers an ideal barrier against oxygen, nitrogen, hydrogen, and carbon dioxide.

Fresh-Keeping Ability
Food packed inside the VPF is able to maintain its quality and freshness over a long time of storage. The film also keeps external odor away from the packed food.

Exceptional Eco-Friendly Material
VPF is an exceptional eco-friendly material that is primarily made up of carbon, oxygen, hydrogen, and silicon. The film is totally bio-degradable, recyclable and can be burned without producing any toxic gases.

CVCI is a specialist VPF products manufacturer. We offer vacuum packaging films in a variety of colors, materials, and sizes to suit your specific needs.
