Using the Mulitvac TopCLOSE process on a labeller, trays can be sealed closed simply, sustainably and attractively by means of self-adhesive labels – and completely without a packaging machine. Mulitvac will be showing how this automatic process works, using a L 330 conveyor belt labeller at Anuga FoodTec (Hall 8.1, Stand C10).
If fruit and vegetables do not require to be packed under modified atmosphere or airtight in a vacuum, self-adhesive labels are the ideal opportunity to secure the content of the tray against falling out or being removed. Thanks to a special manufacturing process, Mulitvac TopCLOSETM labels have adhesive-free zones on the inside of the labels, so that they are permitted for direct contact with food. They can be equipped with a tear flap and a reseal feature, and they are suitable for both right-angled and round trays.
The Mulitvac TopCLOSETM process is performed on the L 330 conveyor belt labeller, and it is possible to print the labels with variable data, as well as subsequently inspecting the label print. The label seals the tray closed automatically on the run, after the trays have been fed in manually or transferred from an upstream module. The conveyor belt labeller can be adapted to different tray sizes and shapes very quickly and easily without the use of any tools. And converting to alternative products, or inserting new label rolls, also involves only the minimum downtime, since the labeller can be set very conveniently thanks to its position displays, which are operated intuitively.
“The high-performance L 330 conveyor belt labeller can save costs, when compared with labour-intensive, manual solutions or automatic packaging machines, and it can achieve closure sealing of up to 250 packs per minute,” explains Ronald Helmel, Business Development Manager at Mulitvac Marking & Inspection. “This also means that food wastage is reduced to a minimum. In addition to this, a zero-downtime version is available for uninterrupted labelling, as well as various automation options such as denesters or product infeed and discharge units.“
At the trade fair Mulitvac will be showing the TopCLOSE process, using a film label with a transparent viewing window for the closure sealing of berries in a cardboard tray. “The proportion of plastic in the pack is under ten percent. Cut-outs in the label provide the necessary air circulation, to ensure that the optimum shelf life for the berries is achieved,” says Ronald Helmel.
