Combining the processability of vinyl polymer with the blocking effect of vinyl alcohol polymer, our ethylene-vinyl alcohol copolymer (EVOH) offers excellent processing performance and outstanding barrier properties against gas, odor, fragrance, and solvent penetration.
With superior thermal stability when combined with ethylene, our EVOH barrier layers in multilayer containers are fully reusable, making them ideal for various packaging applications.
Our EVOH film types include biaxial tensile, aluminum evaporation, and adhesive coating types, suitable for aseptic packaging products and offering excellent gas barrier properties.
Characterized by exceptional gas barrier, transparency, gloss, mechanical strength, and cold resistance, EVOH is widely used in food packaging, aseptic packaging, and non-food applications such as packaging solvents and electronic components.
Our EVOH products can replace glass and metal containers in food packaging, offering enhanced barrier performance and environmental protection benefits. They are also used in cosmetic flexible packaging, floor heating pipes, jelly cups, and pesticide bottles.
Choose EVOH from GYF BIOTECH LTD. for high-quality, environmentally friendly barrier materials that improve product quality and contribute to sustainability.

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 over traditional glass and metal containers in food packaging.
