The present invention relates to an ethylene-vinyl alcohol copolymer (EVOH) resin composition, an EVOH film formed therefrom, and a multilayer structure containing the same. The core height difference (Sk) of the surface of the EVOH resin composition is between 0.6 and 2.0 &#x3bc;m, and the overall standard deviation of Sk is between 0.05 and 0.55. The invention can reduce the torque output during processing to achieve the effect of energy saving, and can also improve the stability during output to obtain a better film appearance.

Ethylene vinyl alcohol copolymer resin composition, ethylene vinyl alcohol copolymer film formed therefrom, and multilayer structure containing the same

The instant disclosure relates to a fluorine-containing ethylene-vinyl alcohol copolymer (EVOH) resin composition as well as mixture and blend thereof. The fluorine-containing EVOH resin composition comprises EVOH and fluorine-containing particles, wherein the fluorine-containing EVOH resin composition has a total fluoride ion content ranging from 45 to 41000 ppm. The invention can reduce the adhesion of EVOH to the inside of the extruder, and effectively reduce the appearance of gel or gelled substance in subsequent finished products.

Fluorine-containing ethylene-vinyl alcohol copolymer resin composition as well as mixture and blend thereof

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 composition and/or pellets thereof may have a boron content of 10 to 450 ppm. EVOH films formed from the EVOH may have a Charpy impact strength of at least 2.5 KJ/maccording to ISO 179-1 at 23&#xb0; C. and an elongation at break of at least 18.2% according to ISO 527-2 at 23&#xb0; C.
