Ethylene-vinyl alcohol copolymer (EVOH): Combining the processability of ethylene polymer with the barrier effect of ethylene alcohol polymer, ethylene-vinyl alcohol copolymer not only shows excellent processing performance, but also shows excellent blocking effect on gas, odor, fragrance, solvent, etc.Due to its thermal stability in combination with ethylene, multilayer containers containing EVOH barrier layers are completely reusable.It is these features that enable plastic containers containing EVOH barrier layers to replace many glass and metal containers in food packaging.
