Technical Field

[0001] The utility model relates to the technical field of fully laminated products, in particular to a UV color-changing label paper. Background Art

[0002] In the production of fully laminated products, OCA optical adhesive is generally used for lamination and fixation during lamination. Many products on the market require UV curing of the OCA optical adhesive. After the product is laminated with OCA optical adhesive, it is sent into a UV furnace for curing. Since the OCA optical adhesive is a transparent material and has no color change before and after UV curing, it is very difficult to distinguish by manual observation of the product, resulting in some products flowing into the client without UV curing, posing a reliability risk.

[0021] In order to facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0022] A UV color changing label paper, refer to Figure 1 , including a label paper 10, which is used to be attached to the product. A QR code 20 is sprayed on the surface of the label paper 10, and the QR code 20 is used to trace the production process of the product. Since fully laminated products need to be laminated and fixed with OCA glue, and OCA glue is transparent and has no color difference before and after UV curing, it is difficult to distinguish whether the product has been UV cured. Therefore, a UV color-changing layer 30 is provided on the label paper 10, and the UV color-changing layer 30 is coated on the upper surface of the label paper 10, and the UV color-changing layer 30 and the QR code 20 are located on the same surface of the label paper 10.

[0023] Further referring to Figure 1 , the UV color-changing layer 30 is located near one edge of the label paper 10, and the size of the UV color-changing layer 30 is smaller than that of the label paper 10. The UV color-changing layer 30 does not contact the two-dimensional code 20, so as not to affect the subsequent traceability of the two-dimensional code 20.

[0024] Referring to Figure 1 , different colors can be changed within the UV color-changing layer 30. By setting the UV color-changing layer 30 on the label paper 10, the UV color-changing layer 30 can change color under UV irradiation. For example, the original color of the UV color-changing layer 30 is transparent or white, and it will change into other distinguishable colors after UV curing. The staff can clearly see the color change with the naked eye, so as to distinguish whether the product has undergone UV curing through the color change of the UV color-changing layer 30, thus avoiding missing the UV curing operation of the product.

[0025] Further, referring to Figure 1 , the UV color-changing layer 30 is made of UV color-changing ink, and the UV color-changing layer 30 can change color after being irradiated by UV to achieve the discrimination effect.

[0026] Further, referring to Figure 2 , the thickness of the UV color-changing layer 30 is 20μm - 30μm.

[0027] Further, referring to Figure 2 , a protective layer 40 is provided on the upper surface of the UV color-changing layer 30. The protective layer 40 is coated on the upper surface of the UV color-changing layer 30, and the protective layer 40 can protect the UV color-changing layer 30 to increase the wear resistance of the UV color-changing layer 30.

[0028] Further, referring to Figure 2 , the thickness of the label paper 10 is 0.05mm - 0.1mm. The label paper 10 is provided with single-sided adhesiveness, and an adhesive layer 50 is provided on the side of the label paper 10 away from the two-dimensional code 20. The adhesive layer 50 is used to attach the label paper 10 to the product for subsequent product traceability.

[0029] Referring to Figure 2 , the thickness of the adhesive layer 50 is 0.02mm - 0.05mm.

[0030] Referring to Figure 2 , an oil paper layer 60 is attached to the side of the adhesive layer 50 away from the label paper 10. The oil paper layer 60 is used to protect the adhesive layer 50 that has not been attached to the product. The oil paper layer 60 has good detachability and can be easily peeled off for tearing when the label paper 10 needs to be attached to the product.

[0031] By setting a UV color-changing layer 30 on the label paper 10, the UV color-changing layer 30 can change color after UV curing, so that when the product passes through UV curing, it can be determined whether the product has undergone UV curing through the color of the UV color-changing layer 30, thereby screening out the products that have not undergone UV curing and avoiding the risk of defective products flowing into the client side.

[0032] The above-described embodiments only represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
