Ethylene-vinyl alcohol copolymer (EVOH)

 

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 effects on gas, odor, fragrance, solvent, and more. Its thermal stability in conjunction with ethylene allows for the creation of reusable multilayer containers with EVOH barrier layers. These features make plastic containers with EVOH barrier layers a versatile and sustainable alternative to glass and metal containers in food packaging.
