Abstract

The invention discloses a printing method for realizing the repeated opening and closing sealing performance of a packing box. After the contact part of the box cover and the tongue paper of the packing box is printed and processed by the water-based flocking ink, the contact surface of the box cover and the bottom box comprises a layer of pattern with flocking effect, the box cover is particularly soft and thick, good in elasticity and high in wear resistance, the local thickness is increased by about 35-45 microns, the normal opening of the packing box is not influenced, when the packing box is closed, the box cover and the tongue paper of the bottom box are tightly closed, the circulation of air inside and outside the box is prevented, the box can be repeatedly used, the process meets the requirements of green and environment protection, the energy consumption is low, and the effect is obvious.

Description

Printing method for realizing repeated opening and closing sealing performance of packaging box

Technical Field

The invention belongs to the technical field of packaging box printing, and relates to a printing method for realizing repeated opening and closing sealing performance of a packaging box.

Background

In order to ensure that commodities in the packaging box can be kept fresh and moisture-proof, the packaging box is generally subjected to plastic package treatment by using PVC, POPP and other preservative films after products are filled in the packaging box, and air circulation inside and outside the packaging box is isolated. However, such a disposal method is only disposable, and when a consumer uses the product, the plastic packaging film needs to be torn off, so that the problem does not exist in the product which is used for one time, but the problem of keeping fresh and moisture after unsealing exists in the product which is not used for one time, such as cigarette packaging. Although the packing carton after tearing the plastic envelope membrane can also cover the box and go back, nevertheless all have closed not tight problem, because the existence in gap between lid and the end box cover leads to inside and outside circulation of air, causes commodity to lose its original taste, lets consumer's experience descend.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: provides a printing method for realizing the repeated opening and closing sealing performance of a packaging box, and aims to solve the problems in the prior art.

The technical scheme adopted by the invention is as follows: a printing method for realizing the repeated opening and closing sealing performance of a packing box comprises the following steps:

(1) coating: in the process of connecting line printing processing, a coating process is added, and the inner side of the box cover of the packaging box and the outer side of the bottom box are coated with glue according to the closed contact overlapping position;

(2) processing and printing with aqueous flocking ink at the same pattern position where coating is finished;

(3) immediately feeding the printed packaging box product into a drying oven for drying treatment;

(4) and (5) collecting paper, namely collecting paper and finishing the printed packaging box product, and sending the printed packaging box product into a post-process for processing.

In the step (1), a specially customized ceramic anilox roller is selected for coating, the plate making parameter is 55-80 lines, and the glue transfer amount is 4-4.5 g/square meter.

In the step (2), the printing is finished by using a gravure laser electro-engraving plate, wherein the plate-making parameter of the gravure plate is 90-110 lines and is 38-45 um.

And (3) drying in an infrared drying mode, wherein 6-8 infrared drying lamps are adopted, one exhaust motor with the power of 37kw is adopted, the air quantity is 35000m for carrying out heavy plantation/h, the air pressure is 2000Pa, and the length of the baking oven is 10-15 m.

The invention has the beneficial effects that: compared with the prior art, after the contact part of the box cover and the tongue paper of the packing box is printed and processed by the water-based flocking ink, the contact surface of the box cover and the bottom box comprises a layer of pattern with flocking effect, the box cover is particularly soft and thick, good in elasticity and high in wear resistance, the local thickness is increased by about 35-45 mu m, the normal opening of the packing box is not influenced, when the packing box is closed, the box cover and the tongue paper of the bottom box are tightly closed, the circulation of air inside and outside the box is prevented, the process can be repeatedly used, the process meets the requirements of green and environment protection, the energy consumption is low, and the effect.

Drawings

FIG. 1 is a schematic process flow diagram.

Detailed Description

The invention is further described with reference to the accompanying drawings and specific embodiments.

Example (b): as shown in fig. 1, a printing method for realizing the repeated opening and closing sealing performance of a packing box comprises the following steps:

The printing process flow of the packing box comprises the following steps: paper feeding, coating, printing, infrared drying (blowing) and paper collection are carried out, as shown in figure 1, 1 is paper feeding, 2 is coating (coating a water-based adhesive), 3 is printing (printing water-based flannelette ink, plate making parameters are 55-80 lines), 4 is infrared drying (6-8 infrared drying lamps are needed, an external oven is used for hot air drying, the length of the oven needs to be lengthened to 10-15 meters), and 5 is paper collection.

The invention provides a direct printing process with high printing efficiency, stable quality and high yield, which is characterized in that a layer of soft, elastic and friction-resistant raised patterns are added on the inner side of a box cover and the outer side of a bottom box by printing at the positions of the box cover and the bottom box of a packaging box through the printing process, so that the contact surface of the box cover and the bottom box is tightly attached when the packaging box is closed, the sealing performance of the packaging box is improved, the packaging box can be opened, closed and kept in a strong sealing performance for a plurality of times after a plastic sealing film is removed, and the functions of freshness preservation and moisture prevention are achieved.

The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of changes or substitutions within the technical scope of the present invention, and therefore, the scope of the present invention should be determined by the scope of the claims.
