The typical packs for four, six or ten eggs are practical and proven. They are generally made of a recycled, paper fibre-based material or transparent plastic. Branding and marking the packs is by means of pre-printing of the box, or alternatively with either a cardboard sleeve or a pre-printed adhesive label on the top of the pack,.
Flexible labeller with a high level of output
Thanks to its L 310 conveyor belt labeller, MULTIVAC can now offer an efficient solution for labelling egg packs made of cardboard or plastic - a solution that provides added value in many respects. The L 310, which has patented, servo-driven press-on brushes, makes automated C labelling and D labelling (as well as traditional top labelling) of packs possible at an output of up to 120 packs per minute. The maximum label width is up to 500 mm. It is possible to run packs with a base width of up to 250 mm and a height of 140 mm.
The labeller can be equipped with a zero downtime function for even more efficiency and process reliability, as well as with an integrated printer and label/print monitoring at even the highest throughput.
Attractive labelling solution
If the L 310 is used for complete wrap-around labelling, the full wrap label automatically seals the egg box closed. For retailers and consumers this means, that the products can not be exchanged or contaminated with viruses and bacteria, or that the packs can not be used to hide stolen products. This solution is therefore the ideal choice for aseptic or pasteurised eggs for the catering trade, hospitals and bakeries, or for infants and pregnant women. Packs such as these have to be sealed in order to guarantee the highest level of safety, sterility and quality.
As regards in particular the pack appeal at the point of sale and the usable area for product promotion, this new concept for egg packaging surpasses the conventional top labelling or pre-printing of the box by far. The full wrap label is also in no way inferior to the cardboard sleeve. It even offers the benefit that, depending on the label material selected, it can be more cost-effective and above all lighter than a sleeve. In addition to this, the full wrap label can be printed on different sides of the pack with variable data such as barcodes, and it can also be applied automatically to the pack. A significantly higher-value look can be achieved for the pack, even with the most cost-effective material.
Versatile and clearly more sustainable
Another benefit of full wrap labelling is its high level of flexibility, since label shape, material type and printing can be individually tailored to the pack. It is possible to run either film labels made of PP or PET for example, or alternatively more sustainable materials made from paper or renewable sources. A perforation feature can be integrated into the label if required, so that the consumer can open the label more easily. It is also possible to have printing on the back of the label for additional consumer information.
Label and packaging material can be matched to each other, so that the constituent parts of the pack can be separated to meet the recycling requirements. Also: in the event of layout changes or faults in the pre-printed egg boxes, the complete stock of boxes must be destroyed, whereas with full wrap labelling it is only the pre-printed labels that have to be replaced.
