Patent ID: 10896988

Abstract:
A laminated sheet of a two-layer sheet in which an L1 layer including 50 to 99 parts by mass of an ethylene-based polymer (E1) having a density of 0.890 to 970 kg/m3 and 1 to 50 parts by mass of a propylene-based polymer (P1) is in contact with an L2 layer including 50 to 100 parts by mass of a propylene-based polymer (P2) and 0 to 50 parts by mass of an ethylene-based elastomer (E2) having a density of equal to or more than 850 kg/m3 and less than 890 kg/m3, in which the propylene-based polymer (P1) includes a propylene-based elastomer (P1a) including a propylene-derived constitutional unit and an ethylene-derived constitutional unit and/or a constitutional unit derived from an α-olefin having 4 to 20 carbon atoms, and having a melting point (Tm) that is lower than 120° C. or not observable; and a solar cell backsheet formed using the same.
