AI Technical Summary

Technical Problem

The existing hot-press film structure design is unreasonable, has poor anti-counterfeiting performance, is easy to be counterfeited, and has poor decorative effect.

Method used

Laser micro-engraving technology is used to set a reflective layer, a positioning base layer, a first laser micro-engraving layer and a nano-particle coating inside the hot-pressed film. It is integrally formed with the heat-sealed film layer through a hot-pressing process, and has a double anti-counterfeiting structure with an additional aluminum plating layer and a second laser micro-engraving layer, combined with the decorative effect of the nano-particle coating.

Benefits of technology

It achieves a dual anti-counterfeiting structure with good internal and external anti-counterfeiting performance, enhances the decorative effect and overall texture, is difficult to counterfeit, has a reasonable structural design, and is highly practical.

Abstract

The utility model discloses a laser micro-carving hot pressing film which comprises a first heat sealing film layer, an aluminum plating layer is fixedly arranged on the lower surface of the first heat sealing film layer, a containing groove is formed in the upper surface of the first heat sealing film layer, and a positioning notch is formed in a groove opening of the containing groove. A reflective layer, a positioning base layer, a first laser micro-carving layer and a nano-particle coating are sequentially arranged in the storage groove from inside to outside, a second heat-sealing film layer is arranged on the upper surface of the nano-particle coating, and the lower end of the second heat-sealing film layer is bonded and fixed to the inner wall face of the positioning notch. The technical scheme is reasonable in structural design, good in anti-counterfeiting performance, not easy to counterfeit, good in decorative effect and good in practicability.
