Combining the processability of vinyl polymer with the blocking effect of vinyl alcohol polymer, our Ethylene Vinyl Alcohol Copolymer (EVOH) offers exceptional gas, odor, fragrance, and solvent blocking properties. With excellent thermal stability, EVOH is ideal for multilayer containers, ensuring reusability.
EVOH is the most widely used high barrier material, available in various film types including biaxial tensile, aluminum evaporation, and adhesive coating types. Its superior gas barrier and processability make it perfect for aseptic packaging products.
Used in both food and non-food packaging, EVOH serves as an intermediate barrier layer in composite films, offering transparency, gloss, mechanical strength, and wear resistance. It can replace glass and metal containers in food packaging, enhancing barrier performance.
Our EVOH products are versatile, suitable for cosmetic packaging, floor heating pipes, jelly cups, and pesticide bottles. As a non-toxic environmental protection material, EVOH improves quality of life while contributing to environmental sustainability.

Discover the innovative ethylene-vinyl alcohol copolymer (EVOH) by GYF BIOTECH LTD. This unique copolymer combines the processability of ethylene polymer with the barrier effect of ethylene alcohol polymer, providing exceptional processing performance and superior blocking effects on gas, odor, fragrance, solvent, and more.
Thanks to its thermal stability when combined with ethylene, multilayer containers featuring EVOH barrier layers are fully reusable. This makes plastic containers with EVOH barrier layers a sustainable and efficient alternative to traditional glass and metal containers in food packaging.
