Holographic Embossing of Idvac White Metallised Film

Idvac Ltd, UK, a specialist in advanced vacuum and thin film technology, has been investigating the properties of its recent development of white metallised coating with high reflection.

Idvac white metallised film is produced by using a special polymer which is transparent when applied on a flexible film. However, the polymer changes its colour to white following vacuum metallising with aluminium. The metallised aluminium can be applied by using thermal evaporation or sputtering. The final product has a bright white metallised finish on front and back surfaces of the film. In this process no inks or white pigments are used.

In a recent development, Idvac in collaboration with IQ Structures, has succeeded in embossing the white metallised film with a holographic structure. This resulted in an aesthetically appealing holographic image on a white background.
