Abstract

The invention relates to the technical field of papermaking, in particular to environment-friendly plastics-absorption double-surface coated white board paper and a preparation technology thereof. The preparation technology comprises the following steps of preparing various layers of pulp raw materials; removing impurities and screening pulp; forming paper by using a screen; squeezing and drying the paper; applying adhesives on the surface of the paper; performing hard press polish; performing coating in a machine; performing soft press polish; and coiling the paper. The various layers of pulp raw materials comprise a surface bleaching chemical pulp layer, a lining waste paper pulp layer, a core waste paper pulp layer and a bottom bleached chemical pulp layer; pulp of the surface bleaching chemical pulp layer consists of 45-55% of LBKP (laubholxer bleached kraft pulp) and 45-55% of DMOW pulp in percentage by weight; pulp of the lining waste paper pulp layer is DIP; pulp of the core waste paper pulp layer consists of 65-75% of MW pulp, 15-25% of BCTMP (bleached chemical thermo mechanical pulp) and 5-15% of waste stuff in percentage by weight; and pulp of the bottom bleached chemical pulp layer consists of 25-35% of LBKP and 65-75% of DMOW pulp in percentage by weight. By the environment-friendly plastics-absorption double-surface coated white board paper, the air permeability, the interlayer bonding force and the printing ink absorption performance of paperboards are improved.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a blister double-sided coated white board paper and a preparation process thereof. Background technique [0002] Blister packaging refers to a process in which coated white board paper or white cardboard is printed, its surface is coated with a layer of blister oil, and then the film is heat-treated and bonded to white board paper or white cardboard. As a packaging material, coated white paperboard also has broad market application prospects in the blister packaging industry. However, in the current paper industry, the domestic production of coated white board paper mainly based on waste paper raw materials has problems such as poor tolerance, low bonding strength, and poor absorption of printing ink due to immature technology. Therefore, on the basis of the production process of ordinary double-sided coated white board paper, through the improvement of formula and preparati...
