Method for producing transfer laser holographic metal packaging material (1378962)
This patent is a method of producing a transfer method laser holographic metal packaging material. According to the following process flow: the release layer and information layer are coated on the surface of the plastic film successively, and then the barrier layer is vacuum-plated, and then one side of the barrier layer of the plastic film is composited with the metal packaging material, and finally the plastic film and metal packaging are applied on the peeling machine. The material is separated, and the laser holographic information layer is transferred to the surface of the metal packaging material to obtain a transparent holographic metal packaging material. The invention can transfer the characters, patterns, logos, etc. through the laser holography to the metal packaging material, widen the scope of application of the laser holography products, and can be matched with ordinary metal color printing, and has more ideal anti-counterfeit performance such as clear information characters, clear patterns, and full ray refraction. And identification, decorative effect.
