Embodiment Construction

[0021] see figure 1 with figure 2 , a position dyeing transmissive anti-counterfeiting white paperboard and a manufacturing method thereof, a white paperboard made by a multi-net multi-cylinder paper machine, at least composed of three or more pulp layers, wherein the white paperboard composed of four pulp layers, its The surface pulp is bleached coniferous wood kraft pulp, the middle white pulp is waste paper deinked pulp, the core pulp is mixed waste paper deinked pulp, and the bottom pulp is waste white paper edge pulp. Different pulps are beaten separately. After the pulp system is processed, the paper materials with a certain pulp concentration are sent to the headbox of the bottom paper material, the headbox of the core layer paper material, the headbox of the middle white layer paper material and the headbox of the surface layer paper material, and are formed on the Internet , it is characterized in that: the core layer paper material and the middle white layer paper ...

Abstract

The present invention relates to an antifalse white paper board and its making method. In particular, it relates to an on-location dyed transmitted antifalse white paper board and its making method. The white paper board made up by using multi-wire and multi-cylinder is formed from face layer, intermediate white layer, core layer and bottom layer, in which on the intermediate white layer paper page and core layer paper page are respectively set on-location dyed colored color strips, the colored color strips on the core layer paper page can be transmitted on the bottom layer paper page adjacent to it so as to form the antifalse mark of said white paper board. Besides, said invention also provides the concrete steps of its making method and application of said antifalse white paper board.

Description

technical field [0001] The invention relates to an anti-counterfeiting white paperboard and a manufacturing method thereof, in particular to a position dyeing transmission type anti-counterfeiting white paperboard and a manufacturing method thereof. Background technique [0002] In the consumer market, some counterfeit goods, shoddy goods and the packaging of counterfeit famous products make consumers hard to guard against, be deceived, entrap consumers, and manufacturers and distributors have suffered very heavy economic losses. [0003] At present, packaging anti-counterfeiting technology is an important means to effectively prevent the manufacture and sale of counterfeit products. Among the many packaging anti-counterfeiting technologies, many anti-counterfeiting technologies use paper or cardboard as the substrate medium. The most commonly used anti-counterfeiting technologies are watermarks, patterns, patterns and other anti-counterfeiting technologies, or adding fluore...
