Different techniques for Glass Bottles

Inkjet printing

One of the most used and reliable solutions is CIJThis technology enables marking directly onto the glass surface with fast-drying, chemical-resistant ink. CIJ is ideal for marking batch numbers, best-before dates and barcodes, even at high speed.

The ink can adapted to the bottle's color and surface to provide good contrast, regardless of whether the glass is clear, colored or frosted.

Laser marking

For even more permanent and durable marking is used laser engravingThe laser etches the information directly into the glass surface, providing an elegant, permanent marking that cannot be worn away. It is a solution that requires minimal maintenance and no consumables, making it both cost-effective and environmentally friendly over time.

This method requires no labels, ink, or other consumables, making it relatively inexpensive. maintenance-free.

Labelling

When the label requires more extensive information or graphic elements, such as CLP/GHS symbols, product names and safety instructions, labelling an excellent complement.

Labels allow for full-color graphics, clear warning information, and larger text areas that can accommodate both product descriptions and legally required labelling. However, for glass bottles, choosing the right label material and adhesive with good adhesion to the smooth surface of the glass, as well as ensuring that they can withstand chemicals, moisture, UV light and temperature differences.

Read more about Glass bottles

Labelling on glass bottles is a central part of safety and traceability in the chemical industry. The bottles often contain substances that require clear and durable information about contents, risks and handling.

Because glass bottles are used in environments where they are exposed to cleaning, transportation and sometimes extreme temperatures, the labelling must be both readable and resistantCorrect labelling ensures that hazard pictograms, batch numbers and product information are always clearly visible – regardless of how the bottle is used or handled.

Correct labelling makes it possible to comply with CLP and GHS requirements, while contributing to safe handling, accurate tracking and a professional impression. By choosing a marking method that is adapted to the properties of the glass and the product's environment, companies can create markings that last – both practically and visually – throughout the product's life.

Questions & Answers (FAQ)

It depends on the application. For variable information such as batch numbers, best before dates and barcodes, we recommend CIJ (Continuous Inkjet), which provides clear and durable marking directly on the glass. For permanent marking, laser engraving is the best choice.
Yes, if you use the right type of ink. CIJ printers with specially developed ink for glass surfaces provide good adhesion and high contrast – even on smooth, glossy surfaces. It dries quickly and is resistant to both moisture and temperature changes.
When reusing or cleaning, laser engraving is recommended, as it cannot be worn away. Ink marking can last very well, but laser provides maximum durability over time.
Absolutely! Labels are perfect when you need more information, graphics or hazard symbols. The important thing is to choose label materials and adhesives that are suitable for glass and chemicals so that they stick properly even when exposed to moisture or temperature changes.
All labelling must comply with the CLP and GHS regulations, which means that information about contents, hazards and safe handling must be clear and easy to read throughout the product's life cycle.
Yes, both CIJ and laser work great even on colored or treated glass surfaces. The important thing is to choose the right contrast – for example, light ink on dark glass or vice versa.
Consider how long the label will last, the environment in which the bottles will be used, and what information is needed. Then we will help you find the most sustainable and cost-effective technology – whether it’s CIJ, laser, or labels.
