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.

EVOH products can not only be used in the production of film, but also can be widely used in cosmetic flexible packaging, floor heating pipes, jelly cups and pesticide bottles, etc. EVOH as a non-toxic environmental protection material, not only can improve people's quality of life, but also plays an important role in environmental protection.
