Overview
EVOH is a high-barrier material that exhibits excellent foaming properties against gases, fragrances, fragrances, solvents, etc. It also has good processability, transparency, mechanical strength, wear resistance and cold resistance. In terms of food packaging, plastic containers with EVOH barrier layers can replace many glass and metal containers.
