Abstract
The subject invention provides a flexible, protective, integral liner comprising at least one first polymer which is a homogeneous linear or substantially linear ethylene/&agr;-olefin interpolymer having a density of from 0.850 g/cm3 to 0.920 g/cm3, and at least one second polymer which is an ethylene/&agr;-olefin interpolymer having a density of from 0.905 g/cm3 to 0.935 g/cm3, provided that the density or the second polymer is at least 0.002 g/cm3 greater than the density of the first polymer. In preferred embodiments, the liner will further comprise an ignition resistance additive. The liners of the invention exhibit an excellent balance of flexibility and strength, and, when an ignition resistance additive is employed, excellent ignition resistance.
