Rainbow film and we common of with color dyeing of color plastic film completely different, it is will two species or variety different refraction index of resin melting extrusion and followed by interval Diego added up 100 layer Shang above, and each layer thickness only for hundreds of nano of plastic composite film, that is, each layer film of thickness quite by to reflection of light of wavelength, more than 200 more layer of film its thickness is 0.02mm. When visible light passes through various interfaces, produce weak reflections and interference, if we do more than more than 100 film thickness of each layer is basically the same, then the same wavelength of light that is reflected in each layer stack, there is interference, you make films showing a colorful rainbow effect.
