Clay coated kraft back material and preparation method of clay coated kraft back

Abstract

The invention provides a clay coated kraft back material and a preparation method of a clay coated kraft back. The clay coated kraft back material comprises 3%-50% of paper pulp and 50%-97% of a kraft material. The clay coated kraft back provided by the invention has the beneficial effect of low papermaking cost, is capable of keeping good printability of a white manila board, and is also capable of providing paper grades, which are relatively high in strength indexes (burst index and ring crush index), and of which the value is between the value of the white manila board and the value of the coated kraft by adjusting a core prime paper pulp material, so as to adapt to the requirements of groups with a relatively large range and special use.

Description

Technical field [0001] The present invention relates to the technical field of papermaking, and in particular to a raw material of coated ox-base whiteboard paper and a manufacturing method of coated ox-base whiteboard paper. Background technique [0002] In the traditional classification of coated cardboard, there is a clear distinction between gray background white board paper and coated kraft cardboard. Gray background white board paper is more inclined to mid-to-high-end printing and packaging materials, and is mainly used to reflect the paper's good printability and Provide perfect printed products, while coated kraft cardboard is mainly used for box board lining, so the physical index requirements of the paper are more stringent. However, there is a vacuum gap in the market segment for coated board paper with high printability and high physical strength. Therefore, it is imperative to research a paper type that can not only meet the good printability but also provide...
