PLASMA TREATED EVOH MULTILAYER FILM

摘要

The present invention relates to barrier film structures and, more particularly, to film structures having EVOH and fluoropolymer in skin layer. The addition of fluoropolymer in the skin layer allows trim recycling and improves the metal appearance in the metallization by reducing die lines and scratches. Improved barrier performances have been achieved by using plasma treatment during metal vacuum deposition in the vacuum chamber.
