Discover the innovative EVOH (Ethylene Vinyl Alcohol Copolymer) from GYF BIOTECH LTD. This high barrier material combines the processability of vinyl polymer with the blocking effect of vinyl alcohol polymer, providing exceptional gas, odor, fragrance, and solvent blocking properties.
EVOH is widely used in packaging for food, dairy products, meat, canned fruit juices, and more. It is also utilized in non-food applications such as packaging solvents, chemicals, and electronic components. EVOH plastic containers are a sustainable alternative to glass and metal containers, perfect for seafood export packaging.
As a non-toxic and environmentally friendly material, EVOH plays a crucial role in improving people's quality of life while contributing to environmental protection. It can be used in cosmetic packaging, floor heating pipes, jelly cups, pesticide bottles, and more.

Combining the processability of ethylene polymer with the barrier effect of ethylene alcohol polymer, ethylene-vinyl alcohol copolymer offers excellent processing performance and exceptional blocking effect on gas, odor, fragrance, solvent, and more. Its thermal stability in combination with ethylene makes multilayer containers with EVOH barrier layers fully reusable. These features make plastic containers with EVOH barrier layers a superior choice to replace glass and metal containers in food packaging.
