Novel production technology of anti-counterfeiting safety line boards

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...

AI Technical Summary

Problems solved by technology

At present, all anti-counterfeiting security threads are equipped with plastic security threads. The production process of embedding or bonding security threads is difficult to control, and the paper is easy to curl, and the positioning of security threads is not accurate enough.
