GN Thermoforming Equipment, Chester, Nova Scotia, has entered the form/cut/stack market with its introduction of the GN800. This high-speed thermoformer is the first GN model that offers movable top and bottom platens and expands the company’s plug-assist machine offering. GN says that the first such machine has been sold to a European processor for production of PET sealed containers.

The GN800 was developed in partnership with Italy’s Agripak s.r.l., which supplied form/cut/stack machines until 2003. GN saw the growing use of form/cut/stack technology and bought the rights to Agripak’s original machine design. It has since added new features to make it a “GN machine,” the company says. It is competitively priced with many standard features.

The GN800 has a forming area of 800 x 570 mm (31.5 x 22.4 in.) and can form 150 mm above and below the sheet line. Cutting force of the forming and cutting stations is 75 tons. The GN800 has additional space between the forming and cutting stations, providing extra cooling time when running heavier gauge materials or PP.

The machine features a standard oven that is four times the index length of the forming area. The machine is equipped with cut-in-place capabilities as a standard feature. The unit also features independent top and bottom servo-plug drives.

The GN800 handles sheet widths up to 880 mm (34.6 in.) and can run sheet thicknesses from 0.25 to 1.5 mm. The unit comes fully equipped and handles all thermoformable grades of PET, OPS, HIPS, PLA, PP, and PVC. GN is currently targeting food, medical, and industrial packaging.
