Over the past 2 years, the most common request we have received from our distributors has been for an ink which offers better adhesion on plastic substrates. New packaging materials are always being developed, particularly in the food and cosmetic industries, which are designed to be non-stick. As a result, there is a need for inks to print onto more ‘difficult’ substrates. These are typically low surface-energy materials such as Polythylene (PE) or oriented Polypropylene (OPP), which are designed to be non-stick. Being non-stick makes it all the more difficult to develop an ink which will do exactly the opposite of what the material is designed to do.
Our R&D department have been working hard to formulate a new ink which will offer improved adhesion on these type of materials. That work has resulted in a new ink which is currently called CJ159 Black. At the present time, this new ink has been tested in Domino, Citronix, Markem-Imaje and Linx printers. We are working to develop versions for other printers and expect it to be ready for Videojet and Hitachi printers shortly.
If you would like any more information, or would like samples for testing, please let us know.
