Embodiment 1

[0024] A corrugated paper printing process for fruit packaging boxes includes the following steps:

[0025] (1) Corrugated paper pretreatment: According to the specifications of the fruit packaging box, the paper is divided and pressed, and the corrugated cardboard is cut according to the pressing line, and then the surface of the cut corrugated paper is cleaned;

[0026] (2) Flexible plate making: According to the designed printing pattern, the photosensitive resin is coated on the plate base, then exposed to ultraviolet light, and then washed, dried, and thermally cured to obtain the required flexible plate for use;

[0027] (3) Corrugated paper surface treatment: Put the corrugated paper cleaned in step (1) into the corona machine, and use high-frequency and high-voltage power supply to corona treatment on the inner and outer surfaces of the corrugated paper, with a corona value of 28W / m;

[0028] (4) Corrugated paper PE coating: the corrugated paper that has been corona treated in ...

Abstract

The invention relates to the technical field of carton printing, in particular to a corrugated paper printing process for fruit packaging boxes. The corrugated paper printing process comprises seven steps of corrugated paper pretreatment, flexographic plate making, corrugated paper surface treatment, corrugated paper PE lamination, outer layer PE lamination surface treatment, flexographic plate printing and polishing and calendaring treatment. The adhesive force between PE lamination and corrugated paper is enhanced through corona treatment, and then a water-based ink and the PE lamination areeffectively combined through low-temperature plasma treatment, so that the combination fastness of an ink layer is improved, and the sealing performance and the moisture resistance of the corrugatedpaper are better through PE lamination; compared with solvent-based ink, the water-based ink does not generate harmful gas, is higher in safety performance, and is cheaper than UV ink, the toughness of a film formed by the water-based ink adapts to that of PE lamination, the brittle fracture phenomenon is avoided, and the defect that the film formed by the UV ink is prone to brittle fracture is overcome.

Description

Technical field [0001] The invention relates to the technical field of carton printing, in particular to a corrugated paper printing process for fruit packaging boxes. Background technique [0002] At present, most of the fruit packaging boxes on the market are made of corrugated paper, but corrugated paper has various deficiencies due to its own materials, such as air tightness, moisture resistance, and wear resistance, which cannot meet the requirements of packaging fruits. In addition, due to the material of corrugated paper, the effect of using water-based inks in the printing process is poor. Therefore, printing companies use more solvent-based inks to achieve printing results, but the solvents in solvent-based inks can cause toxic and harmful emissions. Gas, if used to print fruit packaging boxes, is bound to seriously endanger the physical and mental health of consumers. As for the UV ink, because of its relatively high price and the brittle cracks between it and the surf...
