Problems solved by technology

The plastic film is cumbersome to carry, which often affects the printing efficiency of the film. Moreover, printing holographic patterns on the forward and reverse embossed sides of the plastic film requires high positioning accuracy of the graphics printed on the front and back of the plastic film. The position error of the holographic image embossed on the front and back embossed surfaces of the coating film must be less than 0.01mm. It is difficult to meet the process requirements by using a hot molding machine and a UV molding machine alone for molding.

Embodiment 1

[0032] Taking the molded double-sided coated PET film as an example, in this embodiment 1, the PET film is coated with a printing layer on the positive embossing surface, and the printing layer is used to increase the adhesion between the UV coating and the PET film. The printing layer itself has no imaging function; the reverse embossing surface of the PET film is coated with a holographic molding layer, which is used to carry holographic image information. The specific process of molding is as follows:

[0033] A) Use 3M strong high-temperature double-sided adhesive tape to roll and paste the holographic metal nickel plate on the first roller 2 of the thermal molding system 1;

[0034] B) Utilize 3M strong double-sided adhesive tape to roll and stick a metal optical nickel plate on the second version roller 4 of the UV molding system 3, and the metal optical nickel plate is engraved with optical microstructures, such as microlenses;

[0035] C) according to the optical micr...

Embodiment 2

[0047] The difference between the present embodiment 2 and the embodiment 1 is that in the present embodiment 2, the molding press used for molding the film also includes an adjustment system, and the adjustment system includes a positioning adjustment roller 19, a hydraulic cylinder 20, a detection light source 21 and A detection light source receiving device corresponding to the detection light source 21; the hydraulic cylinder 20 is used as a driving device, and its piston rod is connected with the positioning adjustment roller 19. The detection light source receiving device includes a receiving probe 22 and a computer system, and the receiving probe 22 is data connected to the computer system; the hydraulic cylinder 20 is also connected to the computer system through electronic components.

[0048] In the present embodiment 2, the molding process is as follows:

[0049] A) Utilize 3M strong high-temperature double-sided adhesive tape to roll a holographic metal nickel plat...

Abstract

The invention discloses a mold-pressing method for a laser film. A front turnover system and a rear turnover system are used in the mold-pressing method so that a front UV mold-pressing system and a rear UV mold-pressing system which are connected front and back can mold-press a positive imprinted face and a reverse imprinted face of the film; and an adjusting system is used for guaranteeing that patterns mold-pressed to the positive imprinted face and the reverse imprinted face of the film are accurately aligned. By the adoption of the method, localization is accurate, the film does not need to be carried in the mold-pressing process, and production efficiency is high; and in the production process, the deformation of the film is small, the flatness is good, and the produced film can meet the requirement for high quality.

Description

technical field [0001] The invention relates to the technical field of holographic anti-counterfeiting and holographic laser packaging, in particular to a molding method of a laser film. Background technique [0002] The application of holographic laser image technology on plastic coating films was first introduced from the United States to China at the end of the last century. The principle is as follows: the holographic laser image is imaged on the photolithographic glass coating plate by photographing or photolithography, and then the holographic image on it is copied to the metal nickel plate by electroforming, and then the thickness is about 15~ The 80μm metal nickel plate with holographic laser image is used as the embossing plate and attached to the plate roller of the holographic laser molding machine. The coating film passes on the heated plate with the embossing plate, and the side roll is coated on the plate roller. The first layer of film is pressurized, and the...
