Abstract:
A liner, comprising:a. at least one first layer comprising at least 40 weight percent of a first polymer component which comprises at least one first ethylene/-olefin interpolymer which is a homogeneous linear or substantially linear ethylene/-olefin interpolymer having a density of from 0.850 g/cm3 to 0.920 g/cm3, b. at least one second layer comprising at least 40 weight percent of a second polymer component which comprises at least one second ethylene/-olefin interpolymer having a density of from 0.905 g/cm3 to 0.935 g/cm3, provided that the density of the at least one second ethylene/-olefin interpolymer is at least 0.002 g/cm3 greater than the density of the at least one first ethylene/-olefin interpolymer, wherein the liner has a total thickness of 0.3 to 4 mm, and exhibits a flexural modulus, as determined in accordance with ISO 178, of no more than 150 MPa and an Impact Resistance at âˆ’10Â° C., as determined in accordance with ISO 6603, of at least 35 J/mm.
