Laser encoding gives syringes and vials an indelible ID

As a worldwide innovation Gerresheimer offers a new technique for labelling glass products for pharmaceutics

One square millimetre ensures that the type and origin of glass primary packaging is traceable at any time

The innovation has dimensions of just one square millimetre. For the worldwide pharmaceutics market it means a major step forward in terms of security: with laser encoding Gerresheimer offers a completely new indelible identity tag for prefillable glass syringes and other tubular-glass packaging for pharmaceutics.

The new technology, which also opens up a range of other useful possibilities, is exhibited by Gerresheimer at Interpack 2008 (Hall 7, Stand A01).

In the case of syringes the code appears on the finger rest and in the case of vials on the upper edge for example. To the naked eye it is almost invisible and even under the magnifying glass it does not reveal any of its secrets. Only with special scanners which are available for example to the wholesale pharmacy trade and clinics is it possible to decipher the exact glass product which is involved and where, when and in which batch it was produced and for what species of drug it may have been specifically designed.

This means that primary packaging which perhaps looks identical but may actually have widely differing characteristics can be clearly identified at all times. If they wish, drug manufacturers may also stipulate individual identification data to be incorporated in the coding on the glass.

Gerrresheimer thereby opens up for its customers above all the possibility of a tailor-made track-and-trace solution for the drug traceability proof which is under discussion by the EMEA (European Medicines Agency) and the FDA (Federal Drug Association). This is intended to combat the market for inferior product imitations which is steadily growing around the world. “What laser coding provides is like a finger print for the individual packaging unit,” says Burkhard Lingenberg, Director of Marketing and Communication for the Gerresheimer Group: “This ensures that it can be identified over itsentire life cycle and means that, if necessary, conclusions can quickly be drawn about the origin and for example the expiry date of the medicine which it contains.”

A key factor is the special laser technology which, as far as practically possible, precludes the possibility of subsequent manipulation of the tiny matrix data field. In the Gerresheimer process the code is not just applied onto the glass but indelibly embedded in it by laser. Unintentional damage to the extremely precise product ID thus provided, or any attempt to remove it, would ultimately be detected by the reader appliance in the course of origin checks. The laser bake-in technology has the additional advantage that no particles are released.
