A system for controlling the temperature of a film before and/or during application, the system including: a heat source for heating a film; and stretch rollers; wherein the heat source heats the film from an ambient temperature to a temperature from about 2° C. to about 40° C. above the ambient temperature, wherein the film is heated prior to or simultaneous to being stretched by the stretch rollers, and wherein the ambient temperature is below 15° C. A system for improving the application of film by transfer of electrostatic charge is also described. The preheating system and/or electrostatic charge system may be used to enhance binding and sealing properties of stretch films used for wrapping palletized products in a reduced temperature environment. Other embodiments of the preheating film system and electrostatic charge system, and methods for their use, are described herein.
