FW7-820
The FW7-820 is built for high volume shrink films and flexible packaging up to 32” (810mm) wide. This machine is specially designed to handle big, heavy rolls, and a variety of flexible packaging substrates. Despite its large roll handling capabilities, this brawny Inspection Slitter Rewinder gives up on none of the precise tension control and high-speed defect placement of our smaller nimbler machines.
The FW7-820, like all of our models, requires just one operator to inspect, edit, slit and rewind.
