Water-based inkjet printing as an alternative to laser and thermal transfer printing for dangerous goods labels.
The requirements for dangerous goods labelling are becoming more and more demanding and are forcing label manufacturers and the operators of filling and bottling plants to develop new solutions. Signage specifications include the new requirements from the GHS system, country-specific languages and legal requirements. Additionally, industrial customers are requesting greater flexibility when it comes to the implementation of labelling solutions. They are looking for ways of coping reliably with extremely small print runs and ad hoc needs without any major logistical effort, or would like to be able to customise colour designs for a perfect brand impact.

The traditional approach was to finish pre-printed labels using thermal transfer or laser printing techniques. In recent years, water-based inkjet printing has established itself alongside these methods and is preferred especially for rapidly changing small print runs and for labels with many different language combinations. The drawback up to now has been that there were very few seawater resistant materials suitable for water-based inkjet printing and the requirements were very difficult to fulfil with the existing printers on the market. Most conventional inkjet films were not able to pass the tests for resistance of water-based inks to long-term immersion in seawater and to abrasion of the inkjet coating after rolling in a mixture of sand and seawater.
New material complies with seawater resistance according to BS 5609
New possibilities are now opening up thanks to an innovative self-adhesive material developed by Germany-based company VPF GmbH & Co. KG. This material can be printed in colour with water-based pigment inks while simultaneously fulfilling the stringent seawater resistance requirements specified in the internationally acknowledged standard BS 5609. Beyond its standard portfolio of special self-adhesive materials, the manufacturer offers a complete mix-and-match range of seawater resistant facestocks and adhesives that can be combined at will.

This line includes high-quality self-adhesive materials to suit any printing application, whether thermal transfer, laser or inkjet. In addition to the demanded seawater and abrasion resistance, they are also suitable for dispensing and adhesion to difficult substrates and are also available in increased coat weights.
New legal requirements on dangerous goods labelling
The GHS system (Globally Harmonised System of Classification and Labelling of Chemicals) which came into force in the summer of 2015 brought major changes in the framework conditions for dangerous goods labelling. New hazard pictograms with red borders have replaced the old hazard symbols on orange backgrounds. This has made labelling more complex and also more costly. Conventional multistep label production processes using labels pre-printed with coloured hazard symbols for customisation – either by thermal transfer or laser printing – are now seldom possible because, according to the new regulations, the number of GHS pictograms on the label must be identical to the number of hazards declared for the product.
