Abstract

The invention relates to technical field of coated kraft liner producing method. The producing method comprises feeding surface pulp, lining pulp, core pulp and bottom pulp pumped from machine chest of pulping workshop into respective machine chest; slushing and pressure screening the lining pulp, the core pulp and the bottom pulp by offline back water bank, then slushing and pressure screening the surface pulp by the offline back water bank after removing impurities in the surface pulp in a low concentration sand remover, finally all the pulp entering into a flow box to flow onto wire; after the pulp flowing onto wire, feeding the pulp into a coating system after forming by a four-long net forming machine, second shoe pressing, drying, glue blending, redrying, and press polishing by a two-roller hot pressing machine; feeding the coated paper into a state-regulating cylinder and a soft calendar to finish, then reeling by a horizontal paper reeling machine. The coated kraft liner producing method disclosed by the invention can greatly reduce use cost of the coated kraft liner to make the domestic market not dependent on import any longer.

Description

technical field [0001] The invention relates to the technical field of production methods of coated kraft cardboard. Background technique [0002] Similar to coated white board paper, coated kraft cardboard is applied on the surface of kraft cardboard to improve the performance and application range of kraft cardboard, especially to improve the printing adaptability and physical strength of kraft cardboard, which can be applied to The outer packaging of high-end goods can also be made into packing boxes separately, which are used for packaging of light industrial products, and the product has high added value. [0003] As far as the product is concerned, coated kraft linerboard not only has the strength of ordinary kraft paper, but also has the printing adaptability of coated paper. Under the same packaging requirements, compared with traditional paper packaging methods, it can save more than 1 / 3 of paper, especially in Frozen, vegetable and high-strength packaging have bro...
