A polymeric laminate comprising (A) a substrate, and (B) a slip layer covering at least a portion of said substrate, where the slip layer consists essentially of (i) a polyethylene blend, where said blend includes (a) from about 3 5 to about 97 percent by weight, based upon the total weight of said blend, of a first polyethylene resin having a weight average molecular weight from 110,000 to about 140,000 and a polydispersity of less than about 12, (b) from about 3 to about 97 percent by weight, based upon the total weight of said blend, of a second polyethylene resin having a weight average molecular weight from 50,000 up to 10 109,999 and a polydispersity of less than about 12, and (c) from about o to about 40 percent by weight, based upon the total weight of said blend, of a third polyethylene resin having a weight average molecular weight from about 20,000 up to 49,999 and polydispersity of less than about 12, with the proviso that said blend includes at least 6o percent, based upon the total weight of said blend, of 15 said first polyethylene and said second polyethylene combined, (ii) from about 2.5 to about 15 parts by weight, per 1oo parts by weight of said polyethylene blend, of a propylene polymer or copolymer having propylene units deriving from propylene monomer, and (iii) from about 4.5 to about 20 parts by weight, per loo parts by weight of said polyethylene blend, of a dynamically vulcanized rubber.
