Embodiment 1

[0027] Such as figure 1 As shown, a production process of a novel security thread anti-counterfeiting paper includes the following main steps:

[0028] (1) Manufacture of coating rollers: the production of coating rollers is to form cells on the surface of the coating rollers by electric carving or laser engraving. The depth of the cells determines the coating amount of the thermoplastic coating. Thickness has a greater impact on the quality of subsequent thermoplastic molding. In order to avoid the phenomenon of incomplete information or plate sticking in the molding process, the depth of the coating roller cell in the present invention is 30-50μ;

[0029] (2) Coating: use a coating roller to coat a layer of thermoplastic paint on the plastic base film and dry it. The base film is preferably a PET transfer film; the thermoplastic paint can be diluted with a solvent, and the viscosity of the thermoplastic paint has a certain effect on the molding quality. The influence of las...

Embodiment 2

[0040] (1) Manufacture of coating rollers: the production of coating rollers is to form cells on the surface of the coating rollers by electric carving or laser engraving. The depth of the cells determines the coating amount of the thermoplastic coating. Thickness has a greater impact on the quality of subsequent thermoplastic molding. In order to avoid the phenomenon of incomplete information or plate sticking in the molding process, the depth of the coating roller cell in the present invention is 30-50μ;

[0041] (2) Coating: use a coating roller to coat a layer of thermoplastic paint on the plastic base film and dry it. The base film is preferably a PET transfer film; the thermoplastic paint can be diluted with a solvent, and the viscosity of the thermoplastic paint has a certain effect on the molding quality. The influence of laser coating in the present invention is that the viscosity of the 4# cup is 15-25 seconds. The coating speed is 80-120m / min, and the oven temperatu...

Abstract

The invention provides a novel production technology of anti-counterfeiting safety line boards. The production technology comprises procedures including production of a coating roller, coating, production of a mold-pressing plate, mold pressing, aluminizing, composition, stripping and transferring, varnishing, edge division, slitting and the like. Anti-counterfeiting safety line ivory boards, anti-counterfeiting safety line laser paperboards and the like can be produced with the production technology. According to the production technology, a plastic base film is coated with a layer of thermoplastic material, the coating amount is adjusted by adjusting the ink cell depth of a coating roll, and phenomena of incomplete information or plate sticking during mold pressing are avoided. A transfer film with paper money line information is composited with an ivory board after aluminizing, then the base film is stripped, then the ivory board is coated with a varnish protection layer, and the anti-counterfeiting safety line ivory board can be prepared. The anti-counterfeiting safety line ivory board is composited with the laser transfer line through an adhesive layer, a base film of the laser transfer film is stripped, the board is coated with a varnish protection layer, and an anti-counterfeiting safety line laser paperboard can be prepared. The anti-counterfeiting safety line boards contain no plastic safety lines as well as plastic materials such as surface coated or composite films, overcome the defect that anti-counterfeiting safety line boards are prone to curling, and reduce the production difficulty of embedment of safety lines into boards.

Description

technical field [0001] The invention relates to the technical field of packaging and printing materials, in particular to a production process of a novel security thread anti-counterfeiting paper. Background technique [0002] Safety thread is also called pull wire, window safety thread, which is to bury a metal wire or plastic thread in the paper during the papermaking process. At present, the polyester plastic thread is mostly used. The security thread is very anti-counterfeiting, difficult to copy, and the anti-counterfeiting is more intuitive and easy to identify. It is one of the best anti-counterfeiting measures. Therefore, many packaging and printing materials have imitated and developed customized anti-counterfeiting security thread paper. At present, security thread anti-counterfeiting paper is mainly half-embedded a plastic thread into the paper during the papermaking process, and coating the surface of the paper for protection. The paper is prone to curling due t...
