Glass marking

Laser marked glass vials

CO2 lasers can be used to apply a range of information to glass syringes, vials and tubes for the medical and pharmaceutical industries. Traceability of these products is critical, so the permanent and tamper-proof nature of the laser code is a distinct advantage.

Coding directly on the glass means that the information is not lost if the product is separated from its packaging, or if an adhesive label is removed. Our laser markers can apply both human-readable text and 2D Data Matrix codes on the production line, on the fly, and the glass can be marked hot or cold at any stage of the manufacturing process.

Cold glass marking

CO2 lasers mark glass by making tiny cracks in the surface of the material. The rough texture this produces can mimic a sandblasted effect for decoration, or can serve a practical purpose – for example, a laser mark on the base of a beer glass can keep the bubbles flowing, and the frothy head on your beer

High quality decorative marking is possible; our lasers are used for cosmetics and perfume bottles as well as drinking glasses and crystal glassware.

Cold-end laser marking

Hot glass marking

Marking glass at high temperature allows extremely high quality marks to be produced without cracking. Subtle identification marks, human-readable text and reliable data matrix codes can be applied to glass bottles, jars, vials and other containers at the hot end of production, on the fly.

This may be done for traceability or as protection against counterfeiting of products.

The hot glass manufacturing environment is challenging, but the MULTISCAN® HE is engineered to withstand these harsh conditions.
