A THERMOFORMING MACHINE AND METHOD
20230143337 · 2023-05-11 ·

This thermoforming machine includes a thermoforming chamber having at least one heated air inlet through which heated air flows into the thermoforming chamber at a controlled pressure. The air inlet cooperates with a heated air flow distribution regulator located in the thermoforming chamber and through which the heated air flows out of the thermoforming chamber at a predetermined temperature. The regulator includes a heated air flow regulating mask receiving heated air flow, having a plurality of flow restricting elements providing different air flow restrictions.

Method and systems for applying stretch films/plastic films at a controlled temperature and/or transfer of electrostatic charge
11685105 · 2023-06-27 · ·

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.
