The Preferred Pack PP43ST is a "one step" semi-automatic shrinkwrapper that is simple to use. The operator places the product on the package loading tray in between the two layers of centerfold film. The operator then moves the package into the sealing area and lowers the hood. There is a "L" seal bar in the chamber. Once the hood is lowered by the operator the timed magnetic lock down feature will hold the hood down for an adjustable timed period and then automatically release it. The hood once released automatically returns to the up position. After the seal has been made or the package has been sealed with the film shrunk and the hood returned to the up position, the operator may remove the completed package. The timed magnetic lock/hold down of the hood is an included feature. This machine can either seal only or seal and shrink wrap.
