A winder liner for unvulcanized rubber material comprising a first woven layer, a second woven layer, and a polymer layer. The first and second woven layers each contain a plurality of warp tape elements in a warp direction interwoven with a plurality of weft tape elements in a weft direction and a plurality of interstices between the warp and weft tape elements. The polymer layer is disposed on the inner surfaces of the first woven layer and the second woven layer and in the interstices of the first woven layer and the second woven layer. The polymer layer contains a first polymer comprising a co-polymer having at least 50% alpha-olefin units and is characterized by a number-average molecular weight of about 7,000 to 500,000 g/mol, and a viscosity of between about 2,500 and 150,000 cP measured at 170° C.
