A kind of production method of holographic hot stamping film

Abstract

The invention provides a production method for a holographic hot stamping film. An anti-counterfeiting work plate is formed for silver spraying and electroforming operations of a photoetching offset plate etched with a holographic pattern; a positron emission tomography (PET) thin film is coated with a mold releasing agent to form a mold releasing layer; the mold releasing layer is coated with a resin solution mixed with toner to form a toner layer; the holographic pattern on the anti-counterfeiting work plate is die stamped on the toner layer of the PET thin film; metal aluminum is plated on the toner layer, and a aluminum-plated layer is coated with glue to form a glue layer; and finally, the PET thin film is divided, cut and packed. According to the hot stamping film produced through the production method not only exquisite in pattern, but also high in anti-counterfeiting degree and difficult to counterfeit; a used hot stamping film can not be reused. The photoetching offset plate sprayed with silver is even in thickness and high in strength, so that the rate of finished products of photoetching offset plates is increased by a large margin, and accordingly the quality of the anti-counterfeiting work plate and the hot stamping film is improved; meanwhile, the raw material consumption can be reduced, and the production cycle for making the anti-counterfeiting work plate is shortened. The electroformed anti-counterfeiting work plate has good strength, hardness and malleability resistance; the working life is pronged by near one time.

Description

technical field [0001] The invention belongs to the technical field of packaging anti-counterfeiting and relates to a production method of a holographic hot stamping film. Background technique [0002] With the high development of modern science and technology, counterfeit and shoddy products are constantly changing their appearance, penetrating into various fields, violating the legitimate interests of producers and the rights of consumers all the time. Therefore, anti-counterfeiting fights have become a common concern of the society. With the improvement of the national economy and the development of the printing and packaging industry, people's requirements for product packaging are not only high-end, exquisite, environmentally friendly, and full of personalization, but also hope that the authenticity of the product can be identified through the product packaging. Therefore, the rainbow holographic molded anti-counterfeiting mark with anti-counterfeiting function is more ...

Problems solved by technology

However, the traditional rainbow molded holographic anti-counterfeiting label has an unchanging appearance and a single anti-counterfeiting method, and its anti-counterfeiting strength is greatly weakened due to mutual imitation and illegal forgery among various manufacturers.
