What role does EVOH play in packagingIssuing time:2023-10-31 16:12 EVOH is a high barrier material in packaging. EVOH not only exhibits excellent processing performance, but also exhibits excellent blocking effects on gases, odors, spices, solvents, etc. In addition, it has excellent transparency, glossiness, mechanical strength, scalability, wear resistance, cold resistance, and surface strength. In the field of packaging, EVOH is made into a composite film intermediate barrier layer, which is applied in all hard and soft packaging; Used in aseptic packaging, hot cans, and steaming bags in the food industry, as well as packaging dairy products, meat, canned fruit juice, and seasonings; In non food applications, it is used for packaging solvents, chemicals, air conditioning structural components, gasoline barrel liners, electronic components, etc. In terms of food packaging, EVOH plastic containers can completely replace glass and metal containers. Many domestic aquatic companies export seafood using PE/EVOH/PA/EVOH/PE five layer co extrusion film vacuum packaging. At the same time as accelerating the research on EVOH composite films, foreign countries are also studying the stretching orientation of EVOH. The gas barrier performance of the new EVOH film is three times that of the existing high-performance non stretching EVOH film. In addition, EVOH can also be applied as a barrier material on other synthetic resin packaging materials to enhance barrier performance. EVOH products can not only be used in the production of thin films, but also can be widely used in soft packaging of cosmetics, floor heating pipes, jelly cups, and pesticide bottles. As a non-toxic and environmentally friendly material, EVOH is widely used. |
