Abstract

The invention relates to the technical field of papermaking, in particular to an environmental-friendly black paperboard and a production method thereof. According to the technical scheme adopted by the invention, the environmental-friendly black paperboard mainly comprises a surface layer, a lining layer, a core layer and a back layer in sequence. The environmental-friendly black paperboard is characterized in that both the surface layer and the back layer are provided coating layers, wherein the surface layer is a white coating layer and the back layer is a black coating layer. The environmental-friendly black paperboard has the characteristics of counterfeiting performance, low production cost, environmental protection, high color fastness and light protection; the coating process of a coated duplex board with grey back is adopted at the front of the paper; and the printing performance of the environmental-friendly black paperboard is excellent and the environmental-friendly black paperboard can adapt to the demands of exquisite packaging and printing.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to an environment-friendly black cardboard and a production method thereof. Background technique [0002] At present, although there are many kinds of dyed papers of various qualities, most of the papers are volatile in color, have low light fastness, do not have anti-counterfeiting functions, fade or change in color after a long storage time, and cannot meet the needs of light-proof storage. Packaging needs; black liners or black plastic and cardboard are used in the existing market for various instruments, containers, and chemical packaging that need to be protected from light. There is no special paper or cardboard directly used for packaging. Contents of the invention [0003] The object of the present invention is to provide an environmentally friendly black cardboard and its production method. This black cardboard has stable color fastness, anti-counterfeiting and unifor...
