Embodiment 1

[0022] The present invention is a kind of packaging printing process, comprising the following steps:

[0023] (1) Cut the printing substrate according to the packaging requirements of the packaged object, and the printing substrate is one of tear-resistant synthetic paper and cardboard;

[0024] (2) Cut the polyethylene heat shrinkable film according to the size of the printed substrate cut in step (1); the cut size of the polyethylene heat shrinkable film is the size of the printed material cut in step (1) 1.5 times;

[0025] (3) Printing UV curable printing ink onto the front side of the polyethylene heat shrinkable film;

[0026] (4) Ultraviolet curing of the polyethylene heat shrinkable film completed in step (3) by an ultraviolet curing lamp;

[0027] (5) Apply adhesive on the back of the polyethylene heat shrinkable film that has been cured in step (4), and then attach it to the surface of the printing substrate;

[0028] (6) Take a piece of polyethylene heat shrinka...

Embodiment 2

[0037] The difference between this example and Example 1 is: after the step (4) is completed, before the polyethylene heat shrinkable film is attached to the surface of the printing substrate, the polyethylene heat shrinkable film after the step (4) is completed is baked Dry processing, the drying temperature is 180 degrees Celsius. In the step (7), the pressurization treatment of the printed semi-finished product by the dot-shaped lenticular mold is a hot-pressing method, and the hot-pressing temperature is 180 degrees Celsius. The printing semi-finished product after step (9) is cured is dried, and the drying temperature is 180 degrees Celsius. The irradiation time of the ultraviolet curing lamp in the step (4) is 5 seconds, and the irradiation time of the ultraviolet curing lamp in the step (9) is 12 seconds.

Embodiment 3

[0039] The difference between this example and Examples 1 and 2 is: after the step (4) is completed, before the polyethylene heat shrinkable film is attached to the surface of the printing substrate, the polyethylene heat shrinkable film after step (4) is completed Carry out drying treatment, and drying temperature is 120 degrees Celsius. In the step (7), the pressurization treatment of the printed semi-finished product by the dot-shaped lenticular mold is a hot-pressing method, and the hot-pressing temperature is 120 degrees Celsius. The printing semi-finished product after step (9) is cured is dried, and the drying temperature is 150 degrees Celsius. The irradiation time of the ultraviolet curing lamp in the step (4) is 4 seconds, and the irradiation time of the ultraviolet curing lamp in the step (9) is 8 seconds.

Abstract

The invention discloses a modified packaging printing technology. The modified packaging printing technology includes the following steps that (1), printing base materials are cut according to the packaging requirements of a to-be-packaged object; (2), a polyethylene heat shrinking film is cut according to the size of the cut printing base materials in step (1); (3), UV curing printing ink is printed to the positive surface of the polyethylene heat shrinking film; (4), through a UV curing lamp, UV curing is conducted to the polyethylene heat shrinking film completed in step (3); (5), after curing is completed in step (4), adhesive glue is coated on the back surface of the polyethylene heat shrinking film, and then the polyethylene heat shrinking film is attached to the surface of the printing base materials; and (6), a cut polyethylene heat shrinking film in step (2) is taken, and after the adhesive glue is coated on the back surface of the cut polyethylene heat shrinking film, the polyethylene heat shrinking film is attached to the surface of a printing semi-finished product completed in step (5). According to the packaging printing technology, the printing layer is smooth, the hand feeling is fine and smooth, and paper recovery is facilitated.

Description

technical field [0001] The invention relates to a packaging printing process, which belongs to the field of printing. Background technique [0002] At present, when printing with ultraviolet curable ink, the usual method is to first print the ultraviolet curable printing ink on the substrate through the printing device, and then use the ultraviolet rays emitted by the ultraviolet curing lamp to irradiate the printed layer of the ultraviolet curable printing ink. The printing layer of the UV-curable printing ink is cured and dried to complete the printing. The printed matter obtained by the above-mentioned process has a relatively rough printing layer of the ultraviolet curable printing ink, and the visual effect and hand feel are not good. The Chinese invention patent whose notification number is CN101125500 discloses a printing process, which solves the above-mentioned problems. However, after the printing process disclosed in the above-mentioned patent is printed on the ...
