Abstract

The invention discloses a high-lustre mirror transferring coated paper as well as a production technology and production equipment thereof. The high-lustre mirror transferring coated paper comprises a paper layer, a paper glaze coating and a paper back coating, wherein the thickness of the paper layer is 80-350mu m, the paper glaze coating is a styrene-acrylate resin painting layer with the thickness of 0.5-2mu m, and the paper back coating is the styrene-acrylate resin painting layer with the thickness of 0.5-2mu m. The invention also discloses a production technology and production equipment thereof of the transferring coated paper. Body paper is dried after being subjected to back coating processing to obtain base paper; a coated film and the base paper simultaneously enter composite equipment to obtain composite paper; then the composite paper is dried, cooled, rolled and stripped to obtain a basic film and transfer paper; and finally, the base film and the transfer paper are respectively rolled. The coated paper disclosed by the invention has the characteristics of high-lustre mirror, high smoothness, high anti-curling performance and the like and is environmentally friendly, good printing effect can be brought, the paper back coating is processed to eliminate the phenomenon that the back fluffs, and better anti-curling performance is provided for the paper.

Description

technical field [0001] The invention relates to the technical field of paper treatment, in particular to a high-gloss mirror transfer coated paper and its production process and production equipment. Background technique [0002] In the packaging and printing industry, coated paper is used more and more widely, and is widely used in the packaging of high-end products such as cigarettes, alcohol, cosmetics and gift boxes. High gloss and high smoothness of packaging materials have always been important reference indicators. However, the existing cast-coating process and the coated paper processed by it have the following problems: the processing equipment is expensive, and the equipment investment often needs to exceed 100 million yuan; the production efficiency is low, and the machine speed is generally only 20-60 m / min; The surface gloss of the processed coated paper is 84-88 degrees; the surface smoothness is also low, generally not more than 400 sec.
