Straight sealing bars with a heat sealing band are widely used in film sealing processes. Owing to their good heat conduction, small mass and electromagnetic compatibility, they are generally manufactured from alloyed aluminum and have a rectangular section.
The body of the bar is mostly 30, 40 or 60 mm high and 10, 15 or 20 mm wide. The length ranges from a few centimeters to several meters.
The bars can be equipped with coolant holes in the longitudinal axis on request. They are usually shipped by ROPEX fully assembled with bar end blocks, an underlay for the heat sealing band and teflon tape.
