Abstract

The invention relates to the technical field of aluminum laminated film production, in particular to a laser holographic anti-fake composite aluminum laminated film and a production process thereof.The laser holographic anti-fake composite aluminum laminated film comprises a base film layer, an aluminum laminated layer is arranged on the upper surface of the base film layer, a printing layer is arranged on the upper surface of the aluminum laminated layer, and a gluing layer is arranged on the upper surface of the printing layer; the production process of the laser holographic anti-counterfeiting composite aluminized film comprises the following steps: S1, base material aluminizing: placing a reel film in a vacuum chamber, closing the vacuum chamber, vacuumizing, heating an evaporation boat to 1300-1400 DEG C, continuously feeding aluminum wires with the purity of 99.9% to the evaporation boat, adjusting the unwinding speed, the winding speed, the wire feeding speed and the evaporation capacity, turning on a cooling source, and cooling the aluminum wires in the evaporation boat; and continuously melting and evaporating the aluminum wire on the evaporation boat so as to form a bright aluminum layer on the surface of the moving film after cooling, namely the aluminum-plated film, and carrying out mould pressing, code printing and gluing on the prepared aluminum-plated film to prepare the aluminum-plated film with the anti-counterfeit label.

Description

technical field [0001] The application relates to the technical field of aluminized film production, in particular to a laser holographic anti-counterfeit composite aluminized film and a production process thereof. Background technique [0002] Aluminum-coated film is a bright metal-colored film formed by evaporating high-purity aluminum wire into a gaseous state at high temperature through a vacuum aluminum-plating process, and then when the plastic film passes through a vacuum evaporation chamber, gaseous aluminum molecules precipitate on the surface of the plastic film; [0003] For example, the Chinese patent discloses: printing aluminized base film, publication number: CN103264545B, including functional layer, core layer, sub-functional layer, aluminum layer, functional layer, core layer, sub-functional layer are arranged in sequence and adopt bidirectional after co-extrusion Stretched and integrated; the secondary functional layer is coated with an aluminum layer; the ...
