Vacuum metallized high gloss pet film

Holographic film is a very thin, flexible plastic film [Polyester (PET), Oriented Polypropylene (OPP) and Nylon (Bonyl)] which has been micro-embossed with patterns or even images. Patterns (such as checker plate or diamonds) or an image (such as a tiger) are created by way of an embossing process which can provide a remarkable 3-D effect and/or spectral (rainbow) coloring. The embossing process is akin to cutting tiny grooves into the films surface at various angles and in different shapes. These micro-embossed grooves cause the “diffraction” of normal white light into stunning spectral color. This phenomenon is not unlike the diffraction of white light into spectral colors through a crystal prism.
