| | 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. It also has excellent oil resistance, organic solvent resistance and antistatic capability. It 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. Due to the oxhydryl in the molecular structure of EVOH resin, EVOH resin has the hydrophilia and hygroscopicity. When it adsorb the damp, its gas obstruct capability will be affected. So 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 Oxygen transmission rate can be reduced to a small percentage even one thousandth. According the requirement of the obstruct effect, it can be coated on single side or double sides or even multilayer coated. The production of multilayer coated film for the automatic liquid filling machine, not only solved the moisture absorption problem, but also had a good economical efficiency. To each kind of active ingredient, the low adsorbability, high obstruct capability, it can prevent the loss of effective component; the excellent oxygen resistance, can prevent the oxidation and metamorphism of the effective component; the excellent transparency, can be applied to the oxygen sensitive goods. The packaging content can be solid granules, powdery products, fluid products.
