Programmable marking systems are needed to introduce production optimizations. Therefore the company began the search for suitable systems to replace all of the existing coders, some of which used clichés.
Various technologies from different suppliers were tested for suitability. The task definition was clear: uncomplicated integration into the existing production flows using existing Multivac thermoformers configured with MR cross web labelers. The effort had to be kept to a minimum. Marking containing variable data is applied directly to pre-printed labels before the labels are attached to the sealed trays by a cross web label dispenser. The labels are applied to the top of the trays on some of the packaging lines and to the bottom of the trays on others. Ideally, the existing mountings and frames could be used with the new marking System.
It was possible to continue using the existing frame for the three hot embossing printers which were replaced. Customer-specific frames were designed for the other printers.
The cross web printer completely traverses the line to apply the labeling. Constant motion causes some degree of wear. With minimal effort, the new frame was quickly modified to make it as compact as possible, which saves weight and reduces wear. The built-in print unit applies variable data to the label. Because the print unit and the controller are separate subsystems, the controller can be mounted on the packaging system to save weight, eliminating the need for a special design.
Dependable production flows are important and optimization at our innovative company is an ongoing process. Convenience foods must taste good and be easy to prepare and eat. They also have to look good
