This invention is for LLDPE blends with an ethylene-norbornene copolymer for resins and improved toughness and processibility for film production. This invention provides LLDPE based resins which are significantly improved with respect to their capability to be fabricated into a film layer, particularly by a blown bubble extrusion technique. Films prepared of the LLDPE/E-NB melt blended resins of this invention are significantly improved with respect to certain of their film properties, such as tear strength, without detracting from the beneficial properties that a LLDPE otherwise provides to a film.

[ What is claimed is:] [1.] A composition for fabrication of a film having improved mechanical properties comprising; a melt blended resin, consisting essentially ofa) from 50-90 wt. % of an LLDPE formed of acyclic olefin monomers;b) from 50-10 wt. % of an ethylene-norbornene copolymer having a norbornene content of at least 10 mole % and a T.sub.g less than 60.degree. C.; rein said LLDPE and ethylene-norbornene copolymer components are present in proportion with respect one to another to yield a composite having a norbornene content .ltoreq.1 mole % and .ltoreq.10 mole % and said components are melt blended under high shear to yield a melt blend.
