A process for extrusion

A process for extrusion comprising extruding, under conditions which will provide a shrink film, a linear low density copolymer of ethylene and at least one alpha-olefin having 3 to 6 carbon atoms, said copolymer having (i) a density in the range of about 0.915 to about 0.932 grams per cubic centimeter; (ii) a weight average molecular weight of at least about 250,000 (iii) a ratio of weight average molecular weight to number average molecular weight of at least about 6; and (iv) a copolymer species with a molecular weight of at least about 500,000 in an amount of at least about 8 percent by weight based on the weight of the copolymer.
