Problems solved by technology

[0003] There are also related anti-counterfeiting films in the packaging industry. However, they are basically identified by naked eyes, and the authenticity cannot be accurately judged, resulting in blurred identification, and its anti-counterfeiting functionality has great limitations.
Of course, there are special anti-counterfeiting methods with high prices, but they are not very suitable for the low-end packaging market.

Embodiment 1

[0044] The steps to make an unlocking tablet are as follows:

[0045] 1) Design the interference shading pattern through the computer pattern software, and realize the optical interference (at the same frequency) through the shading printed by the ink of the gravure printing machine. The composition method of unlocking anti-counterfeiting is composed of lines, and it is also designed with interference stripes to prevent scanning, so that it cannot be copied.

[0046] 2) Coating the molded resin layer 2 on the polyester film layer 1 .

[0047] 3) Using a thermal molding process at 90-160° C. to mold grating indentations on the thermoplastic molded resin layer 2 to form a molded grating stripe layer 3 , with a grating indentation depth of 1 μm.

Abstract

The invention discloses a pre-coating film with an anti-counterfeiting key and anti-counterfeiting lock function. The pre-coating film comprises an unlocking piece and a sealing lock. The unlocking piece sequentially comprises a polyester film layer, a mold pressing resin layer and a mold pressing grating stripe layer from top to bottom. The sealing lock sequentially comprises a functional coating layer, a gravure printing thin film layer, a gravure printing ink layer, a bottom coating layer and a hot melt adhesive layer from top to bottom. An anti-counterfeiting image is arranged on the gravure printing ink layer. The anti-counterfeiting image and the mold pressing grating stripe layer are developed through optical interference. Anti-counterfeiting point elements are generated by combining grating and printing thin film, which is an interference principle of the wave optics; images and texts hidden at ordinary times appear because same-frequency optical interference of the unlocking piece and printing shading is generated. Without an unlocking tool, image and text information embedded in solid color, gradient color, plain net and colorful images and texts can not be seen at all.

Description

technical field [0001] The invention relates to a packaging material, in particular to a pre-coating film for anti-counterfeit packaging with functions of anti-counterfeit key and anti-counterfeit lock and a production method thereof. Background technique [0002] At present, most of the packaging films used in the market are glossy, matte, and packaging films with printed color patterns, and most of the films only have packaging properties. With the increasing dependence of product recognition on product packaging and the proliferation of a large number of counterfeit and inferior products, there are also requirements for the uniqueness and non-reproducibility of product packaging. [0003] There are also related anti-counterfeiting films in the packaging industry. However, they are basically identified by naked eyes, and their authenticity cannot be accurately judged, resulting in blurred identification, and their anti-counterfeiting functionality has great limitations.
