The European GHS regulation (EC) No. 1272/2008, referred to as CLP regulation also affects labelling requirements. Because red diamond-shaped symbols and H and P statements now replace the so far used pictograms on orange squares, and the R and S statements (Risk and Safety notes) must be combined on one label.
The Legi-Air Twin from Weber Marking Systems, with its two series-connected printing modules labels different sized pallets, folding boxes and especially barrels, in through feed mode, with small and large label sizes, multi-colored and at various customized positions on the containers.
Integrated controls support the operator in handling the print modules. Both printing mechanisms are of similar design and intuitive to operate. The applicator systems may, if required, also be controlled and networked via Bluhmware.
Apart from the hazard statements “H” and the precautionary statements “P”, the 2-colored warning symbols are also printed in the required quantities and dimensions, as required. Product designations, quantity information, logos, barcodes (1- or 2-dimensional) are tested and proven technology and have been part of the company’s labelling technology system standards for many years.
Only the actually printed foil is used for labels with large, not currently printed areas or with partially printed symbols. The right applicator for every product shape In the Legi-Air product family, this basic system also can be combined with a range of standardized and customized applicators.
The label is applied using the so-called wipe-on method, whereby it is accurately and reliably collected by the passing product and “wiped on”, so to speak. The finished label is evenly peeled off the backing paper, held by vacuum and transported to the barrel by conveyor belts. The processing speed can be extremely high, since the printing process is separate from that of label dispensing. It is recommended to turn a cylindrical product during the labeling process if the length of the label exceeds 1/3 of the barrel diameter. The label width and length depend on the data volume, but this can always be easily adjusted to suit specific customer requirements.
In the chemical industry it is important that warnings, weight specifications, ingredients etc. on the packaging remain permanently and clearly legible. This means that the labelings, depending on product and downstream process, may need to be resistant to acids and solvents. The print- and apply system also processes large label rolls, guaranteeing maximum operating time.
