Document type: .PDF whitepaper


This paper introduces Nanotech’s colour shifting LumaChrome product that has been used in authentication applications for over 20 years. LumaChrome colour-shifting film changes from one distinct colour to another distinct colour when tilting the film, yielding an intuitive and easy to use solution which is extremely difficult to replicate. Availability in multiple formats from a security patch or PSA label for hangtags to full stripe insertion into product packaging, LumaChrome is a highly versatile and powerful tool for securing brands and products.

The ability to de-metallize and use the technology to show numerical characters, overprinted text with multiple colour-shifting options, shows the adaptability of the technology and its strong applications in the brand protection and licensing industry. LumaChrome provides the ultimate in security yet is very simple to use. It is also one of the most durable overt security features, with little to no loss in its characteristics when crumpled. LumaChrome security labels can be used for secure authentication, anticounterfeiting and smart packaging in multiple industries like pharmaceuticals, cannabis, retail, electronics, imaging supplies and more.
