Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: when the invention produces kraft coated paper, since the kraft paper itself is a plant fiber, it is inevitable that it has the effect of absorbing water, but when the kraft paper absorbs too much water, the kraft paper will become too soft. Or loose, affecting the subsequent processing. On the contrary, if the moisture content of kraft paper is too low, it will also increase the hardness and brittleness of the kraft paper, which will easily cause the kraft paper to break when it is bent, which will affect the coating. Kraft paper production

Abstract

The invention relates to a production process of laminated kraft paper. The production process comprises the following steps: step 1, preparing kraft paper; step 2, napping kraft paper; step 3, compounding the laminating master batch; step 4, laminating and compounding the kraft paper; step 5, trimming the laminating kraft paper; and step 6, collecting the laminating kraft paper. The production process has the advantages that the moisture content of the kraft paper can be effectively adjusted during production of the kraft paper coated paper so that the reliability of the kraft paper during subsequent coating production is guaranteed and the production quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of production of coated kraft paper, in particular to a production process of coated kraft paper. Background technique [0002] Coated kraft paper is a kind of coated paper. Coated paper is a composite material coated with plastic particles on the surface of paper through a casting machine. The main feature is that this composite material can be oil-proof, waterproof and heat-sealable. [0003] The existing Chinese invention patent with application publication number CN105694171A can be referred to, which discloses a preparation process of coated paper. The preparation process of the coated paper includes: selection of base paper, selection of coating raw materials, mixing and melting of coating raw materials, coating by a coating machine, hydraulic cooling and forming. The invention effectively reduces the dyeing and drying steps of the existing coating paper manufacturing method, greatly shortens the proc...
