A survey of the die-cutting of labels: Part 2 with Berhalter

"As materials become more complex, thinner and more sensitive, and quality demands grow stricter, a perfect die-cutting solution is more important than ever before." - Dalibor Schuman, Berhalter (Source: Berhalter)

In this interview series a range of companies names the current challenges for the die-cutting of labels, the role of digitization in this regard and how laser die-cutting fits into this industry. Read what Dalibor Schuman from Berhalter thinks about the die-cutting segment at its current challenges.

  1. What are the current challenges for the die-cutting of labels?

Dalibor Schuman: As materials become more complex, thinner and more sensitive, and quality demands grow stricter, a perfect die-cutting solution is more important than ever before. Another challenge is the price pressure on the market which means in certain cases reducing costs by using thinner in-mould labelling (IML) films. Berhalter aims to be the leading company worldwide by die-cutting and processing IML labels as thin as 40 microns and even thinner films. A precise dimensional accuracy of the in-mould labels and especially label stacks is crucial for the faultless functioning of the feed and injection moulding systems, as well as for the attractiveness of the end product.

  1. We are living in a digitized production world, in your opinion, which system is the most suitable for the modern single-pass label printing (rotary/laser) process?

Dalibor Schuman: The processes, like coating, printing, etc. before finally die-cutting influence the overall cost of the labels. Certainly, the solution chosen should be the one that saves the most material possible. However, the printing arrangement depends on the nesting possibilities of the die-cutting system. Basically, on a roll-fed flat-bed die-cutting machine, such as a die-cutting system like Berhalter is offering, the optimum material savings can be achieved.

  1. In general: what are your preferences for certain applications? (Semi) rotary die-cutting or laser die-cutting?

Dalibor Schuman: In close cooperation with our customers and their market needs we have developed already, in 2012, the PRElaser laser technology, which can result in considerable increases in performance and efficiency. This laser technology is an additional system in combination with our traditional flat-bed die-cutting, mostly used for perforations, pre-cuts or other functional applications.

  1. Laser die-cutting is a rather new technology: where do you see the opportunities and limitations of this process?

Dalibor Schuman: The Berhalter PRElaser laser technology can be used for various areas of application. One of the target markets is the so-called multipack yoghurt lids, which can now be pre-perforated using this laser technology so that the yoghurt pots can be individually snapped off and separated without the lid being unintentionally removed. The limitation is on one hand the packaging material which could be lasered and on the other hand still the laser speed which means our traditional flat-bed die-cutting is still much faster regarding die-cutting the label or lid contour for a full cutting web arrangement.
