Marking chemical labels reliably and in accordance with regulations

Perfect print results despite challenging conditions

Proper chemical labels and marking convey clearly perceptible information about the potential hazards of chemical industry products. Labels, stickers and packaging with instructions thus act as a warning - they also prevent counterfeiting and tampering. The requirements for labels in the chemical industry are correspondingly high, because the safety of people and the environment is always at stake. Use professional solutions from Diagraph when you need first-class labels in the chemical industry. The advanced technology of our thermal transfer printers guarantees economy, fast printing and resistant chemical labels.

Hazardous substances

Chemical label printing - Diagraph solutions

When using chemical labels professionally, it is important that the final print depicts all information legibly for everyone. In addition, every chemical label must be resistant to environmental influences so that it can fulfill its informative function in the long term. For this reason, stickers made of PE or PET are often used.

Our thermal transfer printers meet all the print quality requirements described above. They reliably apply smudge-proof and scratch-resistant print images to packaging materials such as plastic film and GHS labels - even under the tough conditions prevailing in industry. In summary, Diagraph thermal transfer printers ensure high-resolution, robust and durable print quality on diverse materials.

KEY FIGURES in extreme environments

Are your products packed in dusty, hot or humid conditions?

Do you have frequent product changes?

Do your print images contain a lot of text?

Our goal is to ensure that your products are simply marked reliably, even under difficult conditions.

Chemical Labels & Marking
Use cases in the chemical industry

The label provides information about the contents and potential risks of a chemical container by means of signs and signal words as well as hazard and safety information. The safety-related warnings and instructions of the chemical labels can be found, for example, on:







Big Bags


In practical terms, a chemical label must adhere reliably to different surfaces such as metal, plastic, glass or wood. And even if the surfaces are dusty, oily or slightly deformed.

Print results

All printing technologies are used for industrial products. You can see some printing examples here:


Even in humid, hot or dusty environments, you can achieve perfect print results with our printing systems, even at high line speeds and high cycle rates.

Connection to your ERP system makes changing print images child's play.

We offer special equipment for large format print images.

Mandatory information on chemical labels

  • Name, address, telephone number of the supplier
  • Nominal quantity of packaging
  • Substance name with an index number/CAS number
  • Hazard symbols
  • 'Caution' or 'Danger' as clear signal words
  • Hazard statements by means of H-phrases and EUH-phrases
  • Safety instructions in the form of P-phrases
  • Supplementary information if required

It is essential to note that all instructions shown on chemical labels are formulated in the language of the country in which the product is marketed. This ensures that the information is not only available, but also understood. In the case of multilingual statements, the statements must be identical. For example, to keep the number of labeling elements manageable, some signal words are superior or inferior to others. In general, the hierarchy Danger before Caution applies, because the protruding danger sign has a higher warning effect.

Precise regulations govern the labeling of products and hazardous substances in the chemical industry. These guidelines are uniformly written worldwide to improve the safety of chemical products, substances and mixtures in national and international trade.

Verordnungen und Vorschriften
GHS (Globally Harmonized System of Classification and Labeling of Chemicals)- Internationally agreed program of the United Nations, valid since June 1, 2015.
- Replaces regulations of individual countries.
- Ensures uniform labeling of hazardous substances worldwide.
- Obliges all producers, importers and suppliers of chemical mixtures/substances to comply with the defined standards.
CLP Regulation (EC) No. 1272/2008 Article 17 ff- Has been implementing GHS in Europe since June 2015.
- Regulates the uniform labeling of chemicals in the European Economic Area.
British Standard 5609 Section 2 and 3- Requirements and specifications for seawater resistance on hazardous substance labels and hazardous goods stickers.

The requirements in the industrial sector are high and range from the harshest environmental conditions to production under clean room conditions. Whether plastic parts, metal surfaces or printed circuit boards - Diagraph printing systems meet all requirements. The result is perfect print images on all substrates and packaging types.

Labels in the chemical industry function as information signs on a product or on its packaging. Their task is to transmit long-term, clearly legible information/instructions/warnings about the relevant substances to people or machines. Within the scope of the labeling obligation, chemical labels depict safety-relevant to explicitly warning information about handling and dealing with the respective product.
