A multilayer, thermoplastic roll wrap film containing at least three polymeric film layers and comprised of an outer cling layer, a non-cling outer layer, and at least one inner polymeric layer. The roll wrap film has at least one inner polymeric layer, located between the outer cling layer and then non-cling outer layer. The non-cling outer layer is preferably comprised of a high pressure, low density polyethylene resin having a melt index of from about 0.5 to about 6. The inner polymeric layer comprises a low polydispersity polymer. The low polydispersity polymer has a polydispersity of from about 1 to about 4, a melt index (I.sub.2) of from about 0.5 to about 10 g/10 min., and a melt flow ratio (I.sub.20 /I.sub.2) of from about 12 to about 22. The roll wrap film has a transverse tear resistance of at least 400 grams/mil as measured by ASTM D1922, a machine direction tear resistance as measured by ASTM D1922 of at least 150 grams/mil and a F-50 dart drop of at least 600 grams. It is contemplated that additional layers may be added to the present invention.
