Discover the innovative ethylene-vinyl alcohol copolymer (EVOH) by GYF BIOTECH LTD. This unique copolymer combines the processability of ethylene polymer with the barrier effect of ethylene alcohol polymer, providing exceptional processing performance and superior blocking effects on gas, odor, fragrance, solvent, and more.
Thanks to its thermal stability when combined with ethylene, multilayer containers featuring EVOH barrier layers are fully reusable. This makes plastic containers with EVOH barrier layers a sustainable and efficient alternative to traditional glass and metal containers in food packaging.
