Problems solved by technology

[0003] (1) The use of solvent-based inks contains volatile organic solvents such as toluene, gasoline, and ethyl acetate, which are toxic and flammable, and cause pollution to the human body, packaged goods, and the environment
[0004] (2) After printing, the plastic film that is difficult to degrade is covered with film adhesive, which increases the pollution of the environment and the difficulty of recycling, which does not meet the requirements of environmental protection.
[0005] (3) The production process is complicated, the production cycle

Embodiment Construction

[0035] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] refer to figure 1 and figure 2 , a method for making a flexo pre-printed carton, comprising the following steps:

[0037] 1) Making flexographic facial paper: Use a flexo printing machine to print patterns on the roll facial paper to be pre-printed to form a flexographic facial paper with a good flexographic pattern.

[0038] Such as figure 1 As shown, the flexo printing process is as follows: place the roll of facial paper to be pre-printed on the paper release shaft of the unwinding device of the flexo printing machine, and the beginning of the roll of facial paper passes through various printing and drying systems, and then is placed on the flexo printing machine. On the shaft tube, the shaft tube is placed on the winding shaft of the flexo printing machine winding device:

[0039] The roll surface pape...

Abstract

The invention discloses a manufacturing method for a flexible preprinted carton. The manufacturing method comprises the flexible printed face paper manufacturing step, the corrugated paperboard manufacturing step, the cutting step, the carton body ground paper forming step and the carton forming step. A pattern layer on face paper on the flexible preprinted carton is formed through flexible printing, water-based ink is used during printing, and toxicity and pollution are avoided; a water-based gloss oil coating is used for replacing a plastic film, and pollution to the environment from the plastic film and film covering glue is eliminated. After the face paper is subjected to flexible printing, the face paper and single-face corrugated paper are combined to form a corrugated paperboard, damage to corrugations from printing is avoided, the edge pressing strength of the corrugated paperboard is improved, and accordingly the crushing resistance of the whole carton is improved; and the product has a high-level color printing effect, and it is ensured that the strength of the corrugated paperboard and the formed carton are not damaged.

Description

technical field [0001] The invention relates to the field of printing, in particular to a method for making a flexo preprinted carton. Background technique [0002] At present, corrugated box printing mainly adopts two printing methods: offset printing and flexographic direct printing: offset printing is to combine corrugated paper and inner paper into a single sheet of single-sided corrugated cardboard, and then cover the sheet of offset printed surface paper with a film. Mounted on a single sheet of single-sided corrugated cardboard to make a carton. After sheet-fed offset printing is laminated, the graphics are exquisite and friction-resistant. It is widely used in the production of high-end color cartons and cartons. However, the further development of offset printing is restricted due to the following problems: [0003] (1) The use of solvent-based inks contains volatile organic solvents such as toluene, gasoline, and ethyl acetate, which are toxic and flammable, and c...
