The carton stitcher joins corrugated cartons with metal stitches instead of glue. It works in the folding and gluing area, after die-cutting, as one of the ways a carton's joint can be closed. Shipping cartons and other corrugated packs that call for a stitched joint can be finished here in-house. A firmly stitched joint helps the carton hold its shape when it is filled, stacked and shipped.
