Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of anti-counterfeiting color-changing pigments, in particular to an anti-counterfeiting color-changing pigment for packaging paper. Background Art
[0002] Wrapping paper refers to paper used for packaging. It has high strength, low moisture content, low air permeability, no corrosion, certain water resistance, and is beautiful to use. Paper used for food packaging is also required to be hygienic, sterile, and free of contaminants. When wrapping paper is produced and processed, in order to ensure the authenticity of the items wrapped inside, it is usually made to have certain anti-counterfeiting properties.
[0003] The existing packaging paper anti-counterfeiting color-changing pigments are usually used to judge authenticity during use by color change. However, in actual use, the color change of the color-changing pigments has a certain regularity when reflecting light and is easy to be imitated. For this reason, we propose a packaging paper anti-counterfeiting color-changing pigment. Utility Model Content
[0004] In view of the above problems, the utility model provides an anti-counterfeiting color-changing pigment for packaging paper, which can solve the problems existing in the above background technology.
[0005] The technical solution of the utility model is:
[0006] A packaging paper anti-counterfeiting color-changing pigment comprises a packaging paper body, a base pigment is arranged on the top of the packaging paper body, a first color-changing layer is arranged on the top of the base pigment, a second color-changing layer is arranged on the top of the first color-changing layer, and a third color-changing layer is arranged on the top of the second color-changing layer.
[0007] In a further technical solution, a protective layer is provided on the top of the third color-changing layer.
[0008] In a further technical solution, the first color-changing layer includes a first transparent layer, and first color-changing particles are arranged on the top of the first transparent layer.
[0009] In a further technical solution, the second color-changing layer includes a second transparent layer, and second color-changing particles are provided in the middle of the top of the second transparent layer.
[0010] In a further technical solution, the third color-changing layer includes a third transparent layer, and third color-changing particles are symmetrically arranged on the top of the third transparent layer.
[0011] In a further technical solution, the first color-changing particles, the second color-changing particles and the third color-changing particles are interlaced with each other.
[0012] In a further technical solution, rectangular through holes are equidistantly provided inside the packaging paper body.
[0013] The beneficial effects of the utility model are:
[0014] 1. Through the first color-changing layer, the second color-changing layer and the third color-changing layer, the color-changing particles in the first color-changing layer, the second color-changing layer and the third color-changing layer can reflect corresponding colors during use, and the color of the first color-changing layer can pass through the second color-changing layer and the third color-changing layer, which makes it difficult to imitate and process, and thus has a certain degree of anti-counterfeiting performance;
[0015] 2. Through the rectangular through hole, the whole can be quickly pulled and cut through the rectangular through hole. The overall structure is simple and can be divided into the required size, which is convenient for packaging items and easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0023] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.
[0024] Example:
[0025] like Figure 1-Figure 5As shown, a packaging paper anti-counterfeiting color-changing pigment comprises a packaging paper body 1, a base pigment 2 is provided on the top of the packaging paper body 1, a first color-changing layer 3 is provided on the top of the base pigment 2, a second color-changing layer 4 is provided on the top of the first color-changing layer 3, and a third color-changing layer 5 is provided on the top of the second color-changing layer 4.
[0026] The working principle of the above technical solution is as follows:
[0027] During use, the first color-changing layer 3, the second color-changing layer 4 and the third color-changing layer 5 can make the whole color change to prevent counterfeiting, and the first color-changing layer 3, the second color-changing layer 4 and the third color-changing layer 5 are staggered with each other, which is not easy to imitate, thereby achieving a certain degree of anti-counterfeiting.
[0028] In another embodiment, if Figure 1 As shown, a protective layer 6 is provided on the top of the third color-changing layer 5 .
[0029] This makes it possible for the protective layer 6 to protect the entire surface.
[0030] In another embodiment, if Figure 2 As shown, the first color-changing layer 3 includes a first transparent layer 7 , and first color-changing particles 8 are provided on the top of the first transparent layer 7 .
[0031] This makes it possible for the first color-changing particles 8 to reflect light and change color.
[0032] In another embodiment, if Figure 3 As shown, the second color-changing layer 4 includes a second transparent layer 9 , and second color-changing particles 10 are provided in the middle of the top of the second transparent layer 9 .
[0033] The second color-changing particles 10 can reflect light and cooperate with the first color-changing particles 8 to present different color combinations.
[0034] In another embodiment, if Figure 4 As shown, the third color-changing layer 5 includes a third transparent layer 11 , and third color-changing particles 12 are symmetrically arranged on the top of the third transparent layer 11 .
[0035] The third color-changing particles 12 can reflect light, thereby cooperating with the first color-changing particles 8 and the second color-changing particles 10 to reflect different colors that are interlaced with each other, and the operation is convenient.
[0036] In another embodiment, if Figure 2 , Figure 3 and Figure 4 As shown, the first color-changing particles 8, the second color-changing particles 10 and the third color-changing particles 12 are interlaced with each other.
[0037] The first color-changing particles 8 , the second color-changing particles 10 and the third color-changing particles 12 are interlaced with each other and can reflect different colors to the outside as a whole.
[0038] In another embodiment, if Figure 5 As shown, rectangular through holes 13 are equidistantly provided inside the packaging paper body 1 .
[0039] When the whole is pulled through the rectangular through hole 13, the whole can be quickly torn apart, which is convenient for cutting and separating the whole and wrapping with articles for protection.
[0040] The working principle of the utility model: during use, the whole is pulled through the rectangular through hole 13, so that the whole can be quickly cut according to the size of the article, so that the whole can quickly wrap the article, and when in use, the first color-changing particles 8, the second color-changing particles 10 and the third color-changing particles 12 are cross-coordinated with each other, and can reflect different colors to the outside, which is not easy to imitate, so it has a certain anti-counterfeiting property and is easy to use.
[0041] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
