Laser film generally adopts computer dot matrix lithography technology, 3D true colour holographic technology, multiple and dynamic imaging technology, etc. The holographic image with rainbow dynamics and three-dimensional effect is transferred to PET, BOPP, PVC or coated substrates by molding, and then the surface of the product packaging can be obtained with a certain laser effect by lamination, hot stamping, transfer, etc. It has the excellent ability of resisting ink erosion, blocking water vapor and carbon dioxide. At the same time, the laser film has high gloss for cigarettes, and the holographic layer endows the film with better antistatic properties, anti-blocking properties and high machine adaptability.
