It provides an efficient solution for C labeling and D labeling and enables the hinged tray to be securely sealed on one or both sides.
Multivac's labeler is suitable for a wide variety of different pack shapes - from rectangular to round or oval packs, and even including special shapes such as those for cake slices. The only requirement is that the tray must be sufficiently rigid in its shape and offer adequate contact surface for the label.
Label material grades from 80 g/m2 up to 170 g/m2 can be run. Plastic-based label materials such as PP and PET not only provide transparent labeling of the pack, they also enable the different components of the pack to be separated and directed to existing recycling streams. And even paper labels with an adhesive, which allows them to be separated from the pack by the consumer, or alternatively with a soluble adhesive (for separation in the recycling process) can be used to ensure that the packs have the optimum recycling properties.
PACK EXPO Las Vegas and Healthcare Packaging EXPO (Sept. 27-29, Las Vegas Convention Center) will reunite the packaging and processing community. With over 1400 exhibitors, no other event in 2021 will bring together a more comprehensive gathering of suppliers offering new products, technologies and solutions. Attendee registration is now open.
In addition to being able to apply just a simple top label, the L 310 can apply a label in a C shape over three sides of the pack or in a D shape over all four sides, and it is also possible to overlap the label on the underside of the pack. Both C labeling and D labeling offer the benefit, that the pack is sealed closed at the same time. An additional perforation feature can be used as an opening aid.
The packs are automatically labeled on the run, and they are either fed in manually or transferred automatically from an upstream module. The L 310 can also be equipped with an integrated printer, as well as a zero downtime function and label/print monitoring for maximum output and process reliability at even the highest throughput. In conjunction with a high number of labels on the roll, this provides appreciable cost savings and a highly efficient process, when compared with time-consuming, manual packaging solutions.
A further plus point as regards efficiency is the rapid change of label rolls and batches, which soon pays dividends, particularly if there is a wide variety of products. All the setting parameters for the labeler and the print layout for the integrated printer are stored in the particular recipe, and these are called up automatically when a batch is changed. If an optional splice table is used, experienced operators can perform a label roll change in less than a minute.
