Composition for encapsulant film and encapsulant film comprising the same

Abstract

Provided are a composition for an encapsulant film, and an encapsulant film using the same and having excellent volume resistance and light transmittance, wherein the composition includes an ethylene/alpha-olefin copolymer satisfying the following conditions (a) to (c): (a) a density is 0.85 to 0.89 g/cc; (b) a melting temperature (Tm) having a maximum peak in a curve obtained by differential scanning calorimetry (DSC) is 40 to 90° C.; and (c) the melting temperature (Tm) and an elution temperature (Te) having a maximum peak in a curve obtained by cross-fractionation chromatography (CFC) satisfy Equation 1: 35° C.<Tm−Te<65° C.  [Equation 1]
