Claim 14:
15. A method for producing a film, the method comprising the steps of:
(a) providing a thermoplastic polymer composition comprising (i) a polyethylene polymer composition having a Melt Relaxation Produce of 50,000 or less; and (ii) calcium bicyclo[2.2.1]heptane-2,3-dicarboxylate;
(b) heating the thermoplastic polymer composition to a temperature sufficient to melt the thermoplastic polymer composition so that it may be extruded through a die;
(c) extruding the molten thermoplastic polymer composition through a die having a slot-shaped die orifice to form a film exiting the die orifice;
(d) passing the film exiting the die orifice over a cooled surface to solidify the thermoplastic polymer composition; and
(e) collecting the film.
