Combining the processability of vinyl polymer with the blocking effect of vinyl alcohol polymer, our ethylene-vinyl alcohol copolymer (EVOH) offers excellent processing performance and superior blocking effect on gas, odor, fragrance, solvent, and more.
With exceptional thermal stability when combined with ethylene, our EVOH barrier layers in multilayer containers are fully reusable.
EVOH is the most widely used high barrier material, available in various film types such as biaxial tensile, aluminum evaporation, and adhesive coating types, suitable for aseptic packaging products.
The barrier property of EVOH depends on the ethylene content, where higher ethylene content may reduce gas barrier properties but enhances processability.
Our EVOH is known for its outstanding gas barrier, processability, transparency, gloss, mechanical strength, scalability, wear resistance, cold resistance, and surface strength.
In packaging, EVOH is used as a composite film intermediate barrier layer for both hard and flexible packaging, including food industry applications like aseptic packaging, hot POTS, dairy products, and more.
EVOH plastic containers are a sustainable alternative to glass and metal containers, widely used in seafood packaging and other industries for enhanced barrier performance.
Our EVOH products are versatile, suitable for cosmetic flexible packaging, floor heating pipes, jelly cups, pesticide bottles, and more, contributing to environmental protection and improving quality of life.
