Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings: the positioning multi-color anti-counterfeiting coated white paperboard of the present invention, it at least consists of face pulp, core pulp and base pulp to form a multi-layer pulp through a paper machine to make a single-faced white paperboard and through a paper machine. The surface is coated, and at least one pigment is spray-coated on at least one layer of the multi-layer paste and compounded in the middle of the multi-layer paste. The multi-layer slurry also includes at least a lining slurry, and the multi-layer slurry is composed of a face slurry 1, a lining slurry 2, a core slurry 3 and a base slurry 4, figure 1 Five layers of paste are shown, and in other embodiments, there are at least three or more layers of paste.

[0018] At least one layer of the multi-layer slurry is sprayed with at least two colors of pigments, figure 1 In the process, pigments of di...

Abstract

The invention relates to location multicolor fake prevention coated manila and its production technique. It is made by surface coating and paper machine-made to form single side patent white board formed by starch, core, bottoming multilayer pulp. Its production technique includes the following steps: producing starch, core, and bottoming pulp; copying paper; drying; coating; press polish; and balling up. In copying paper process, coloring pigment is sprayed on the multilayer pulp to make the place with coloring pigment stay on the pulp surface. Thus the invention has the advantages of visual fake prevention discrimination, low cost, and good quality.

Description

technical field [0001] The invention relates to a positioning multi-color anti-counterfeit coated white paper board and a production method, belonging to a special paper and a papermaking process. Background technique [0002] Coated white paperboard is a kind of paperboard. Due to its exquisite surface treatment, it is suitable for various color printing, so it is a good material for manufacturing various packaging boxes, high-end clothing liners, notebook covers and other products. This kind of coated white paperboard is generally made of face pulp, lining pulp, core pulp and base pulp into single-sided white paperboard through a paper machine, and then coated on the surface. The specific production process is: 1. Surface pulp production: Wood pulp—chain conveyor—hydraulic pulper—high frequency fiber refiner—conical refiner—double disc refiner—filler and cationic starch in pulp pool—pulp pump—pulp distribution box—paper Machine stock pool—white water tank outside the mach...
