Background

In the laser holographic laser anti-counterfeiting packaging industry, a specially designed laser holographic laser nickel plate is molded to the same plate surface by combining different laser effects through a molding process, but the coating surface is generally a single coating, as shown in fig. 3. Holographic laser at the packing marking pattern is not used in other areas, and the packing impression effect is improved on the whole. The whole transparent effect or the metallic luster effect can be selected and finished by the coating process. The plating medium material (mainly zinc sulfide) can realize transparent effect, and if the package is required to have metallic luster, a metal aluminum layer can be selected for plating.

Furthermore, the transparent effect and the metallic luster effect can be realized on the same surface through an aluminum washing process, as described in patent document CN102492921A, aluminum is plated and washed on the holographic laser film surface, and a dielectric layer is plated on the aluminum washing portion, so that the effect that the metallic aluminum surface and the dielectric surface appear simultaneously can be achieved, as shown in fig. 4. However, the aluminum washing process is complex, the cost of a protective layer coated by the aluminum washing process is high, and the subsequent alkali liquor used for washing aluminum needs a matched environment-friendly treatment process, so that the treatment cost and pollution influence is large.

On the other hand, the market demand is that different plating effects with different laser effects are displayed on the same layout, so that the anti-counterfeiting and aesthetic effects can be improved, but the anti-counterfeiting and aesthetic effects are difficult to realize in the conventional process.

(3) Heating the glued first laser effect dielectric film at the specific position obtained in the step (2) through a drying tunnel, so that the solvent in the glue material at the glued position is volatilized and removed, and the glued first laser effect dielectric film at the specific position is obtained;

The medium of the first laser effect medium film is a zinc sulfide medium or other mediums. The preparation process of the first laser effect dielectric film and the second laser effect aluminizer is the same as that of the aluminizer or the dielectric film with different laser effects in the prior art.

In some embodiments of the present invention, the first laser effect dielectric film includes a composite base film, a paint imaging layer, and a dielectric layer. The dyne value of the base film of the first laser effect dielectric film is larger than the dyne value of the base film of the second laser effect aluminizer.

The dry-type composite adhesive generally adopts polyurethane type, adopts a two-component solvent type polyurethane adhesive, has the characteristics of strong initial adhesion, high peel strength, quick curing, good wettability to a film and the like, and is suitable for a high-speed composite processing process. The drying tunnel in the device is mainly used for processing the dry-type composite adhesive, so that the solvent is volatilized, and the poor peeling of the aluminizer with the first laser effect is avoided.

In some embodiments of the invention, when the sizing roller with the pattern is used for sizing the first laser effect dielectric film, the first laser effect dielectric film can be sized only at the specific position corresponding to the pattern. In some embodiments, the patterned applicator roll has a patterned roll surface having deep-grained cells engraved therein, and the non-patterned region is smoother than the patterned region, such that when the patterned applicator roll passes through the trough with rotation of the applicator roll, the deep-grained cells lift the composite tape up and rotate above to contact the face of the first laser-effect dielectric film, thereby transferring the composite tape to the face.
