Abstract
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/cm3 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.
Claims15
1) A film comprising at least one layer, wherein the at least one layer comprises:
