We utilize a hardened rotary die cutter to cleanly cut the patch entirely from the film roll stock. This method produces only a slight gap between each cutout pattern. The film waste is reduced by 15% to 20% compared to traditional sealing equipment. There are additional savings when using a narrower width roll and lighter gauge thickness film.

The die cut pattern is carried across a vacuum drum from the die cutter onto a rotary vacuum turntable. This process is done in continuous motion without losing position.

The sealing heads travel directly above the disk picking up the patch by means of a vacuum assist. The patch is then applied to the top of the container. An optional clamping mechanism is employed for unstable containers with a weak sealing flange or column strength.

A typical film skeleton will look similar to the one illustrated in this picture. Film waste is removed from the equipment through a PVC pipe to a bin for disposal.

The finished result is a precision placed sealed patch with minimal film overhang around the perimeter of the container. The patch is smooth with no jagged serrations for easy overcapping and customer handling.
