An extruded film manufactured by a process having the steps of manufacturing a compounded composition by compounding: a polyolefin; a first component that is: a polyethylene glycol, a polyethylene glycol mono-ester, a polyethylene glycol di-ester, a polycaprolactone, a polypropylene glycol, a polypropylene glycol mono-ester, a polypropylene glycol di-ester, a polyethylene-glycol polypropylene-glycol copolymer, an ester prepared from a copolymer of polyethylene glycol and polypropylene glycol, a polyethylene-glycol polycaprolactone copolymer, or a polypropylene-glycol polycaprolactone copolymer; a second component that is a phosphorus-containing compound having one of the following two structures: wherein each R1, R2, R3, R4 and R5 is independently selected and is a C10-C18 alkyl moiety; n is an integer ranging from 3 to 11; and the sum of x1+x2 is an integer ranging from 1-251, or wherein each R1, R2, R3 and R4 is independently selected and is a C10-C18 alkyl moiety; m is an integer ranging from 3 to 11; and x is an integer ranging from 1 to 122; and a third component that is a salt; wherein the compounded composition does not include a fluorine-containing compound; and manufacturing an extruded film using the compounded composition, wherein the film has reduced melt fracture relative to a film manufactured by the same process and with a compounded composition that is otherwise the same but does not include the first, second, or third component.
