EVOH can be regarded as EVA modified material. It has both ethylene polymer good process capability and vinyl alcohol polymer high gas obstruct capability. It is a new colorless, transparent obstruct material, with PVDC and PA, these three materials are the best barrier resin in the world. EVOH can regenerate and does not contain Chlorine and Dioxin,it is to be called green environmental production. In some areas, the EVOH has gradually replace the metallized film, aluminum foil and rigid container. It is being received various countries attention and shows the best potential growth trend in the market. EVOH is used as the middle layer, usually coated with polyolefin. The damp quantity can be control aboratively, to use multilayers coated technic to packing EVOH resin (such as polyolefin).
After many years research, we discovered that if we select the international import raw materials, use the latest co-extruded process flow, the production which contains the EVOH high obstruct ability. Then compound many kinds of base materials like PE, PP, PVC, polystyrene, PET, PA and so on. The packaging content can be solid granules, powdery products, fluid products.
