Problems solved by technology

[0003] Printing logos on the back paper of high-strength reflective film is difficult to play an anti-counterfeiting effect on the main body, because when the reflective film is used, the back paper is used as a protective paper and will not be brought to the reflective film product , so when the reflective film is made into products such as reflective signs, the anti-counterfeiting of the back paper loses its continuity
[0004] Laser printing anti-counterfeiting on the surface of high-strength reflective film requires a large investment in equipment. The anti-counterfeiting production is processed after the product is completed, which causes certain damage to the surface layer of the reflective film and affects the reflective effect.
And the anti-counterfeiting process is separated from the product manufacturing process, which is easy to imitate and difficult to achieve real anti-counterfeiting

Abstract

The invention discloses a manufacturing method of a high-strength grade reflective membrane with an invisible anti-counterfeiting label. Glass beads are planted on a thin film coated with a resin layer and aluminum is plated on the thin film in a vacuum manner, so an aluminum plated film is formed. A white resin layer is coated on a thin film base material with low surface energy. After the thin film base material dries, a smooth thin film is formed. Anti-counterfeiting patterns are printed on the thin film layer, so an adhesive film with the patterns is formed. The adhesive film and the aluminum plated film are recombined via a high temperature roller, so a light reflecting with the anti-counterfeiting patterns is formed. The light reflecting layer and a high-molecular resin thin film are embossed at high temperature on an embossing plate roller, so an embossing layer of a high-strength grade reflective membrane is obtained. Pressure sensitive adhesive is coated on back paper or a back membrane with the anti-adhesion performance, and then the back paper or the back membrane and the embossing layer are recombined. According to the invention, the anti-counterfeiting patterns are completely embedded into the inner structure of the high-strength membrane, so it is difficult to counterfeit or physically or chemically clean the anti-counterfeiting patterns, so the anti-counterfeiting function can be truly achieved and the light reflecting effect will not be damaged. The light reflecting effect is not affected by the anti-counterfeiting patterns which is integrated into the resin layer, so the anti-counterfeiting patterns are high in weather resisting ability and long in service lifetime.

Description

technical field [0001] The invention relates to the field of reflective materials, in particular to a method for manufacturing a high-strength reflective film with invisible anti-counterfeiting marks. Background technique [0002] Modern anti-counterfeiting technology is more popular, but the anti-counterfeiting technology used on high-strength reflective film is mainly to print logo on its back paper, or laser print on the surface of high-strength reflective film. [0003] Printing logos on the back paper of high-strength reflective film is difficult to play an anti-counterfeiting effect on the main body, because when the reflective film is used, the back paper is used as a protective paper and will not be brought to the reflective film products Therefore, when the reflective film is made into products such as reflective signs, the anti-counterfeiting of the back paper loses its continuity.
