Audited Supplier Combining the processability of vinyl polymer with the blocking effect of vinyl alcohol polymer, the ethylene-vinyl alcohol copolymer (EVOH) offers excellent processing performance and superior blocking effect on gas, odor, fragrance, solvent, and more.
With exceptional thermal stability in multilayer containers, EVOH barrier layers ensure full reusability, making it the most widely used high barrier material in various industries.
EVOH comes in different film types, including biaxial tensile, aluminum evaporation, and adhesive coating types, suitable for aseptic packaging products and other applications.
Its barrier properties are dependent on the ethylene content, with higher ethylene content leading to decreased gas barrier but improved processability.
Notable features of EVOH include excellent gas barrier, transparency, gloss, mechanical strength, scalability, wear resistance, cold resistance, and surface strength.
Used extensively in packaging, EVOH is ideal for food industry applications like aseptic packaging, hot POTS, dairy products, meat, canned juices, and non-food items like solvents, chemicals, and electronic components.
EVOH plastic containers can replace glass and metal containers in food packaging, offering enhanced barrier performance for seafood exports and other products.
Furthermore, EVOH is versatile, finding applications in cosmetic packaging, floor heating pipes, jelly cups, pesticide bottles, and more, contributing to environmental protection and improving quality of life.
