Disclosed in embodiments herein are monolayer or multilayer films. The films include at least one layer including a) a polyethylene polymer component comprising linear low density polyethylene; and b) a wax component comprising nonpolar, polyethylene wax, wherein the nonpolar, polyethylene wax has a density of 0.955 grams/cm.sup.3 or greater, and wherein the nonpolar, polyethylene wax is present in an amount of at least 3 percent by weight of the film. Also disclosed in embodiments herein are related compositions and methods of making monolayer or multilayer films.

A process may include contacting ethylene monomer with Ziegler-Natta catalyst to form polyethylene. The Ziegler-Natta catalyst may be formed by contacting an alkyl magnesium compound with an alcohol and a metal reagent to form a blend, and contacting the blend with a first agent to form a solution of reaction product A. The solution of reaction product A may be contacted with a second agent to form a solid reaction product B, and the solid reaction product B may be contacted with a third agent to form a solid reaction product C. The solid reaction product C may be contacted with a fourth agent to form a solid reaction product D, and the solid reaction product D may be contacted with a fifth agent to form a catalyst component.
