Abstract
The instant disclosure relates to ethylene vinyl alcohol copolymer resin composition and/or pellets thereof including one or more fluorine-containing micro-particles. The ethylene vinyl alcohol copolymer resin compositions and/or pellets thereof may have a melting pressure of 1.7 to 7.0 MPa at a shear rate of 20 s−1 and a melting point temperature of 190° C. EVOH films formed from the EVOH may have a Charpy impact strength of at least 2.3 KJ/m2 according to ISO 179-1 at 23° C. and an elongation at break of at least 17.8% according to ISO 527-2 at 23° C.
