Efficient gravure and film covering process of corrugated board

Abstract

The invention provides an efficient gravure and film covering process of a corrugated board. The efficient gravure and film covering process comprises the following steps that a corrugated molding machine is adopted to corrugate the corrugated board, and a lining is attached onto the corrugated board; an adhesive is applied to a web paperboard; nanometer silicon dioxide is applied to the positionof the adhesive; a pattern is pressed onto the web by a platen roller and a rubber roller, and a film is covered; composite corrugated board and pre-printed paper are synthesized by a surface attaching machine; mold cutting and creasing are conducted by a mold cutting and creasing machine; corrugated boards after mold cutting and creasing are positioned in an automatic folding machine in batch; and each creasing is folded, and sealing part is glued. The adhesive is applied to the corrugated board firstly, and then the nanometer silicon dioxide is applied to the adhesive, and therefore the nanometer silicon dioxide is attached to the adhesive. The pattern is pressed onto the web by the platen roller and the rubber roller, and therefore large area being shaded without white is achieved. Small figures and texts are shaded thickly and clearly and with continuous lines. The printing rage is wide, and efficiency is high.

Description

technical field [0001] The invention belongs to the field of printing technology, and more specifically relates to a high-efficiency gravure coating technology for corrugated cardboard. Background technique [0002] Continuous gravure printing, mostly printed on coated kraft cardboard, as a substrate, it has good surface smoothness, thick printing, less white spots, but high cost, complicated process, large footprint, and low printing efficiency; The cost of board paper is low, but the surface is rough, uneven, uneven, and uneven. When printed as a face paper, uneven coloring, false white printing, and broken lines often occur. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the object of the present invention is to propose a printing process for corrugated cartons. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] A high-efficiency gravure coating process for corrugat...
