Inkjet coding and marking solutions for glass surfaces
Batch designation, best before, ingredients and often also reusable labeling: many different markings are applied to glass packaging for consumer safety and recycling. This can be done reliably with our inkjet coding and marking systems.

INKJET MARKING ON GLASS CONTAINERS
Disposable or reusable? This disposal question plays a major role in the choice of coding and marking systems for glass packaging. Reusable glass bottles, such as beer bottles and mineral water bottles, must not be permanently marked. It has to be possible to completely remove the marking in the cleaning system. This is why returnable glass packaging is usually printed using an inkjet printer. The inks used are FDA-compliant and food-approved and are no longer visible after bottle cleaning. Pigmented inks are also available for printing on dark glass such as amber glass or green glass, which enable high-contrast marking.
What is important when it comes to inkjet coding and marking solutions for glass?
- Reliable work in industrial production
- Easy integration into filling systems
- Completely removable marking for returnable bottles
- Food-safe inks
- Legal requirements such as VerpackG, European Packaging Directive 94/62/EC
- Food Information Regulation (LMIV) (EU) No. 1169/2011, Lot Marking Regulation (LKV)
We integrate our inkjet systems for printing on glass seamlessly into filling lines for beverages, food, pharmaceuticals and cosmetics. They first have to be designed for the high line speeds, especially in the beverage industry. Small, multi-line imprints with numbers and letters have to be in exactly the right place and be perfect to read, even when 100,000 or more bottles are filled per day. In the food and beverage industry, production and filling often takes place in wet or humid environments. The inkjet printer then has to print accurately despite condensation on the glass, for example. To achieve this, the systems need protection against splashing water (protecion class IP65) and should work with quick-drying, moisture-resistant and, if necessary, heat-resistant inks.
Industrial inkjet coding and marking solutions are used wherever glass packaging is marked. A wide variety of jars and bottles, flacons and cans made of glass are marked.
Application examples for glass marking
- Bottle neck marking with variable data
- Colored contrast printing on dark glass types
- Bottle printing with quick-drying inks
Discover the various application possibilities of our industrial inkjet coding and marking solutions. They enable process reliability, automation and consumer safety when marking glass products and glass packaging.
According to §32 of the German Packaging Act (VerpackG), all drinks packaging has to be clearly marked with the words EINWEG or MEHRWEG, at least in the same size as the price label. This does not apply to sparkling wine, wine, juices and packaging with a capacity of more than three liters.
The EU directive standardizes the disposal of packaging across Europe and aims to reduce the impact of packaging and packaging waste on the environment. In Germany, it is implemented by the Packaging Act.
The EU regulation regulates which information must be provided on drinks packaging: List of ingredients, best before date (BBD), net quantity, alcohol content in percent by volume (%vol) if greater than 1.2 %vol, caffeine content for energy drinks (not for coffee and tea).
In the LKV, the Federal Ministry of Health has stipulated that only foodstuffs with a batch number consisting of letters, numbers or letters and numbers may be put into circulation in Germany. This allows them to be clearly assigned to a production batch.
