Combining the processability of vinyl polymer with the blocking effect of vinyl alcohol polymer, EVOH (Ethylene vinyl alcohol copolymer) offers excellent gas, odor, fragrance, and solvent blocking properties. Its thermal stability makes multilayer containers with EVOH barrier layers fully reusable.
EVOH is widely used in packaging for food, dairy products, meat, canned fruit juices, condiments, solvents, chemicals, and more. It is also utilized in cosmetic flexible packaging, floor heating pipes, jelly cups, and pesticide bottles.
Choose EVOH by GYF BIOTECH LTD. for high-performance barrier material that meets your packaging needs.
