Plastic label can be inkjet printed


Schreiner MediPharm’s applies a water-based coating to parts of the label to allow marking with inkjet printing systems

Schreiner MediPharm, a German developer and manufacturer of multifunctional labels for the pharmaceutical industry, has developed a label that makes it possible to print plastic films with water-based inks using inkjet systems.

Transparent films are frequently used in the industry to mark glass containers and until now water-based inks have not been suitable for printing plastic films with inkjet systems as the inks cannot be absorbed by the material.

Schreiner MediPharm has found a solution to this challenge by applying a water-absorbing coating to parts of the plastic label, which makes variable marking with inkjet printers and water-based inks possible.

The company says it takes less than a second for the ink to dry on the label, which can be designed so that the barcode is located underneath a laminate and thus protected from mechanical abrasion and moisture ingress, for example by disinfectants.

For very narrow containers, Schreiner MediPharm offers a version of the label where the barcode section lifts slightly, which makes it easier to read.
