Abstract
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. The preheating 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 methods for its use, are described herein.
Claims8
A system for controlling the temperature of a film before and/or during application, the system comprising:
- a heat source for heating a film, said heat source configured to provide a targeted application of heat directly to the film, wherein the heat source is positioned so as to provide heat directly to a surface of the film and across a width of the film on at least one roller, and 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, and wherein the ambient temperature is below 15° C.
