Description

Technical Field

[0001] The utility model generally relates to the technical field of printing, in particular to a waterproof printed product. Background Art

[0002] In some scenarios, some printed materials need to be waterproofed, such as packaging boxes (bags) that are in direct contact with liquids, or used for cold chain transportation and produce condensation on the surface, as well as some printed materials that work or are stored in environments with high humidity, such as posters and brochures posted outdoors.

[0003] The existing waterproof treatment method mainly involves laminating or printing waterproof coating on the outside of printed products. Among them, the process of laminating on the outside of printed products causes great environmental pollution, high cost, and affects the performance of printed products, such as causing the thickness of the printed products to be too large or the stiffness to be too large. The method of printing waterproof coating on the surface of printed products has poor waterproof performance and affects the performance of printed products, causing the printed products to be reflective or blurred from the side and front perspectives, and it is impossible to accurately obtain the information printed on the printed products. In addition, the existing waterproof treatment method needs to be processed on the finished printed products. The size of the finished printed products is small, which is not conducive to large-scale production and leads to high costs.

[0032] The following describes embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0033] Figure 1 The structure of the waterproof printed product 100 according to the embodiment of the utility model is shown below. Figure 1 The waterproof printed material 100 will be described.

[0034] like Figure 1 As shown, the waterproof printed product 100 includes a substrate 110, a waterproof layer 120 and a printing layer 130. The substrate 110 is a substrate of the waterproof printed product 100 (not indicating direct printing on the substrate 110), and the substrate 110 can be various types of paper, fabric or plates of other materials. The substrate 110 is generally a flat plate structure with two opposite surfaces.

[0035] The waterproof layer 120 is located on the surface of at least one side of the substrate 110 and is bonded to the surface of the substrate 110. The waterproof layer 120, for example, includes a curable material, which is formed on the surface of at least one side of the substrate 110 by means of scraping, spraying, printing, soaking, etc., and forms the waterproof layer 120 after curing. The waterproof layer 120 can prevent or reduce the contact of liquid with the surface of the substrate 110 to achieve a waterproof effect. The properties of the curable material such as the component ratio, fluidity, and curing conditions can be set according to the actual application scenario and processing conditions. In a preferred embodiment of the utility model, the curable material is applied to the surface of the substrate 110 using an anilox roller to improve the uniformity of the thickness of the waterproof layer 120, and then baked and cured.

[0036] In some embodiments of the present invention, the substrate 110 is substantially in a planar shape, and a waterproof layer 120 is disposed on the surfaces of two opposite sides of the substrate 110. For example, the waterproof printed matter 100 is a label that can be hung, and both sides may be exposed to liquid or high humidity environments. Providing the waterproof layer 120 on the surfaces of both sides of the substrate 110 can improve the waterproof performance of the waterproof printed matter 100. The thickness of the waterproof layer 120 on the surfaces of both sides of the substrate 110 can be the same or different.

[0037] Furthermore, the substrate 110 includes, for example, paper. The paper needs to be cut during processing to obtain a size that meets the use requirements. Usually, the original size of the paper is larger than the size of the final product. For example, the waterproof printed matter 100 is a waterproof label on a packaging structure. During processing, the waterproof layer 120 can be formed before the paper is cut. The average cost of forming the waterproof layer 120 on a larger paper is lower, and the product quality is easier to control. However, the structure of traditional waterproof printed matter cannot support this processing method, and it is easy to have misprints, resulting in a decrease in the yield rate of the product and difficulty in further reducing the cost.

[0038] In different embodiments of the present invention, the waterproof layer 120 can be formed at part of the surface of the substrate 110. For example, some areas on the surface of the substrate 110 need to be waterproofed, while other areas do not need to be waterproofed. In this embodiment, the amount of curable material used can be reduced, which is beneficial to reducing production costs.

[0039] The printing layer 130 is located on at least a portion of the surface of the waterproof layer 120 away from the substrate 110. The printing layer 130 carries printed content, which may include text, pictures, etc. After the curable material is cured, the printing layer 130 forms ink on the waterproof layer 120 by printing, for example, wherein the printed content is preset.

[0040] When the waterproof layers 120 are disposed on the surfaces of both sides of the substrate 110 , the printed layer 130 may be disposed on the surface of one of the waterproof layers 120 , or may be disposed on the surfaces of both waterproof layers 120 .

[0041] In practical applications, the main reason for the damage of printed products by liquids is that the substrate deforms after being immersed in water, while it is relatively easy to perform hydrophobic treatment on the ink. In the existing technical solutions, the ink printed on the substrate has different bonding ability with the waterproof material than the substrate material, and the ink formed by printing has a certain thickness, resulting in differences in the thickness of the waterproof material formed on the printed product. This situation causes the waterproof layer formed on the surface of the printed product to fall off easily, affecting the waterproof performance. At the same time, the thicker the waterproof material on the printed product, the more it will affect the visual performance of the printed product. For example, reflections may appear when viewed from the side, reducing the viewing angle of the printed product.

[0042] The structure of the waterproof printed product 100 in this embodiment is to form a printing layer 130 on the surface of the waterproof layer 120, and the bonding strength between the waterproof layer 120 and the substrate 110 is higher and more uniform. At the same time, during processing, the curable material can be formed by scraping and the like, and the thickness of the waterproof layer 120 is larger, which can effectively prevent liquid from penetrating into the substrate. According to a preferred embodiment of the utility model, the thickness of the waterproof layer 120 ranges from 8 to 15 microns, for example, 10 microns. In addition, in the structure of the waterproof printed product 100 in this embodiment, the waterproof layer 120 can be formed on the uncut substrate 110, which is conducive to controlling processing costs and improving quality stability. On the other hand, the printing layer 130 is located on the outer surface of the waterproof layer 120, and the visual performance effect of the printing layer 130 will not be affected even if the thickness of the waterproof layer 120 is large. At the same time, different coatings that enhance the visual performance effect can be formed on the printing layer 130, further improving the functionality of the waterproof printed product 100.

[0043] In the field of printing technology, it is difficult for printing equipment to form a thicker waterproof layer 120. The thickness of the printed layer formed by conventional printing equipment is generally not more than 5 microns. For the waterproof layer 120 that needs to be formed over a large area, multiple printing methods will not only lead to a decrease in work efficiency, but also easily lead to stratification, affecting product quality. Preferably, a scraper can be used to brush the curable material on the surface of the substrate 110, and the waterproof layer 120 is formed after curing. At the same time, the processing method of the waterproof layer 120 is also affected by the properties of the curable material. For example, when the fluidity of the curable material is poor, it is not suitable to use silk screen printing to print and form it.

[0044] According to a preferred embodiment of the present utility model, Figure 2As shown, the waterproof printed matter 100 further includes a second functional layer 140, which is located on a side of the printed layer 130 away from the waterproof layer 120, and the second functional layer 140 completely covers the range covered by the waterproof layer 120. The second functional layer 140 can be selected from different materials according to the actual application needs of the waterproof printed matter 100. The fluidity of the material of the second functional layer 140 is greater than the fluidity of the material of the waterproof layer 120. For example, the second functional layer 140 uses different materials to achieve different functions such as dustproof and antistatic, and can also be used to further enhance the waterproof performance. Specifically, for example, the second functional layer 140 is used to improve the waterproof performance. The material of the second functional layer 140 can be selected from flexographic waterproof varnish or coating, preferably transparent color, which can be printed on the printed layer 130. The waterproof layer 120 can be selected from resin, and modified materials can be added, and can be formed on the surface of the substrate 110 by scraping or rolling.

[0045] In practical applications, the printing layer 130 usually does not completely cover the range of the waterproof layer 120, but is only printed at the position where the preset text or picture needs to be formed. The second functional layer 140 is used to achieve different protective functions. In this embodiment, the range covered by the second functional layer 140 completely covers the range of the printing layer 130. Preferably, the range covered by the second functional layer 140 completely covers the range covered by the waterproof layer 120. For example, the waterproof layer 120 and the second functional layer 140 are both configured to completely cover the surface of the substrate 110.

[0046] Preferably, the thickness of the second functional layer 140 can be reduced to avoid affecting the visual performance of the printed layer 130. For example, the thickness of the second functional layer 140 is approximately in the range of 2-5 microns, preferably 2 microns. The second functional layer 140 with a smaller thickness can be formed on the surface of the printed layer 130 by full printing, which is conducive to simplifying the processing technology.

[0047] like Figure 3 As shown, in a preferred embodiment of the present invention, the waterproof printed matter 100 further includes a surface effect layer 150, which is used to improve the visual performance of the waterproof printed matter 100, and is located on the side of the printed layer 130 away from the waterproof layer 120. Specifically, the surface effect layer 150 may have, for example, an anti-reflection function, a reflective visual effect, a frosted visual effect, a color-changing visual effect, etc. The surface effect layer 150 may specifically include transparent ink, highlight ink, or matte ink to achieve different visual effects. Furthermore, the surface effect layer 150 may also be configured to add a reflective sheet to the ink.

[0048] In this embodiment, the surface effect layer 150 is configured to completely cover the range covered by the printing layer 130 , that is, the printing layer 130 is located between the surface effect layer 150 and the waterproof layer 120 .

[0049] In some embodiments of the present invention, the surface effect layer 150 is configured to completely cover the waterproof layer 120. Further, the surface effect layer 150 completely covers the surface of the substrate 110. In other embodiments of the present invention, the surface effect layer 150 is configured to only cover the printing layer 130.

[0050] The surface effect layer 150 may be configured to have a certain waterproof effect, for example, transparent ink, high gloss ink or matte ink etc. have a certain waterproof effect, which can further improve the waterproof effect of the waterproof printed product 100 .

[0051] According to a preferred embodiment of the present invention, the thickness of the printing layer 130 and the surface effect layer 150 ranges from 2 to 5 microns, for example, 2 microns or 3 microns, and the thickness of 2 to 5 microns can be formed by printing with conventional printing equipment, which is conducive to simplifying the processing technology of the waterproof printed product 100. Furthermore, the printing layer 130 and the surface effect layer 150 can also be processed by continuous printing to improve work efficiency.

[0052] Preferably, the second functional layer 140 and the surface effect layer 150 are not disposed on the surface of the printing layer 130 at the same time, so as to avoid a coating layer with too large thickness on the surface of the printing layer 130 , which would affect the visual performance of the waterproof printed product 100 .

[0053] According to a preferred embodiment of the utility model, the substrate 110 is made of paper, such as coated paper, cardboard, corrugated paper, gray board, photo paper, etc., which can be selected according to actual needs. In this embodiment, a rough structure (not shown in the figure) is provided on the surface of one side of the substrate 110 close to the waterproof layer 120 to improve the bonding strength between the substrate 110 and the waterproof layer 120, and a rough structure (not shown in the figure) is provided on one side of the waterproof layer 120 close to the printing layer 130 to improve the bonding strength between the waterproof layer 120 and the printing layer 130, and can also provide a frosted touch and visual performance effect for the waterproof printed product 100.

[0054] Specifically, the substrate 110 may be selected from paper with a relatively rough surface, or the surface of the paper may be processed, such as roughening or sticking. The rough structure of the waterproof layer 120 near the printing layer 130 may be formed when the waterproof layer 120 is formed, for example, the waterproof layer 120 is formed by brushing with a scraper or rolling with a roller, and the scraper or roller may be provided with an uneven structure, such as a protrusion or a depression. When a curable material with poor fluidity is brushed or rolled on the surface of the substrate 110, a waterproof layer 120 with a rough structure may be formed after curing. Furthermore, the waterproof layer 120 may be set to a relatively large thickness, such as 10-15 microns, to prevent the surface of the substrate 110 from being exposed and affecting the waterproof performance.

[0055] In a preferred embodiment of the present invention, Figure 4 As shown, the side of the substrate 110 in the waterproof printed matter 100 is also provided with a waterproof edge 160, and the waterproof edge 160 is pasted on all the sides of the substrate 110 in the circumferential direction. Specifically, the waterproof edge 160 can be a roll material pasted on the circumference of the substrate 110, or a curable material can be pasted on the circumference of the substrate 110 using a device, for example, a plurality of substrates 110 are aligned and stacked and pressed, and the plurality of substrates 110 are controlled to slide relative to a roller, and the outer surface of the roller has a curable material, so that the waterproof edge 160 is formed on all the sides of the circumferential direction of the substrate 110.

[0056] In a preferred embodiment of the utility model, the waterproof layer 120 can also be set to an opaque structure and cover one side surface of the substrate 110. In this embodiment, the substrate 110 may not be dyed, bleached or coated. For example, the substrate 110 is cardboard, and white cardboard is generally coated with white pigment on the outside of the paper core. Printing on the white cardboard can form a printed image with a white background. The waterproof printed product 100 in this embodiment is provided with a waterproof layer 120 on the surface of the substrate 110. The waterproof layer 120 can be set to an opaque structure, for example, by adding pigment to the curable material, and the printing layer 130 is provided on the surface of the waterproof layer 120, with the color of the waterproof layer 120 as the background color. This embodiment can save the cost and process of coloring the substrate 110, and the initial color of the pulp will not affect the final presentation effect of the waterproof printed product 100.

[0057] Finally, it should be noted that the above description is only an embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
