Ethylene vinyl alcohol copolymer resin, film containing the same and multilayer structure, and method for forming ethylene vinyl alcohol copolymer resin

摘要

Problem to be solved: to provide an ethylene vinyl alcohol copolymer resin of pellet form, a film and a multilayer structure containing the pellet form, and a method of forming the ethylene vinyl alcohol copolymer resin.The pellet has at least two melting point temperatures and has a light transmittance exceeding 8% relative to the visible light wavelength.The haze of the pellet may be less than 99.8%.How to produce EVOH pelletsObtaining a first solution containing a first ethylene vinyl acetate having a first ethylene content andA second ethylene containing vinyl acetate having a second ethylene content (second ethylene content) is obtainedDifferent from the first ethylene content.Solution mixing processSaponification processThe pellet is formed by the use of a mixed solution and the pellet is formedPelletContact with boron solution andDrying the pellet and.Diagram
