Combining the processability of ethylene polymer with the barrier effect of ethylene alcohol polymer, ethylene-vinyl alcohol copolymer (EVOH) 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 completely reusable. These features make plastic containers with EVOH barrier layers a superior choice for food packaging, replacing traditional glass and metal containers.
