If the cardboard boxes include windows, OPP or PVC material is applied using our 95 cm-wide window patching machine. This process is carried out with a strong emphasis on quality and aesthetics. In the final stage, during the folding and gluing process, a variety of box types—such as side lock, crash lock bottom, 4- and 6-corner boxes, conical boxes, and double-wall boxes—can be processed up to a maximum width of 110 cm. With our TURNPRO machine, complex gift boxes with integrated lids can be rotated from 0° to 90° on the line and glued in a single pass. Additionally, some of our machines are equipped with glue detection and code printing systems, enhancing both the safety and quality of our operations.
