Abstract

Ethylene-vinyl alcohol copolymer resin composition pellet(s), films, and multi-layer structure formed therefrom, as well as methods for preparing such ethylene-vinyl alcohol copolymer resin composition pellets are provided herein. The ethylene-vinyl alcohol copolymer resin composition typically comprises at least two melting point temperatures, and a boron compound, wherein the ethylene-vinyl alcohol copolymer resin composition has a boron content of about 25 to about 300 ppm and has an iodine dyed region of about 0.1 mmor less after dripping 0.01 mL of iodine solution on the surface of the ethylene-vinyl alcohol copolymer resin composition, dipping the ethylene-vinyl alcohol copolymer resin composition into water for 5 seconds, and drying at a temperature of 120° C. for 2 hours.
