Description

Technical Field

[0001] This utility model relates to the field of pressure-sensitive adhesive label technology, specifically a PI pressure-sensitive adhesive label. Background Technology

[0002] Pressure-sensitive adhesive labels, also known as self-adhesive labels, consist of a substrate coated with pressure-sensitive adhesive on one side, laminated with a release liner to form a roll or sheet, with the desired pattern printed on the other side of the substrate, and then die-cut into the required shape. They are used for decoration, indication, and sealing.

[0003] Most existing pressure-sensitive adhesive labels only consider that the pressure-sensitive adhesive adheres to and fixes the label to the product, making the label very difficult to peel off and damage. They do not take into account that the information on the label can be partially destroyed by rubbing and scraping, resulting in incomplete display of some product information.

[0004] Therefore, it is necessary to provide a PI pressure-sensitive adhesive label to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a PI pressure-sensitive adhesive label to solve the problems existing in the background technology. The technical solution of this utility model addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PI pressure-sensitive adhesive label, comprising a substrate, a pressure-sensitive adhesive layer disposed on the top of the substrate for adhesive application, and a printing layer disposed on the top of the pressure-sensitive adhesive layer for isolating adhesive objects and for printing patterns or text information.

[0007] Preferably, the printed layer includes a release paper adhered to the top of the pressure-sensitive adhesive layer, the release paper having a thermal coating on top, and the thermal coating having a protective film on top.

[0008] Preferably, the substrate surface is brown and has a thickness of 65µm, the pressure-sensitive adhesive layer is prepared using a 20µm thick transparent composite adhesive, and the release paper surface is white and has a thickness of 80µm.

[0009] Preferably, the thermosensitive coating is prepared using a water-based coating, and an adhesive is added to the thermosensitive coating.

[0010] Preferably, the protective film is made of PU film.

[0011] Any aspects of this utility model not described in detail are well-known technologies to those skilled in the art.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The thermal coating of this invention can form information printing through a chemical reaction using heat or light energy. The thermal coating is located at the bottom of the protective film, which protects the information on the thermal coating and makes it difficult to scratch off the label information by rubbing. It has a good information protection function. The pressure-sensitive adhesive layer and the release paper are transparent white and will not affect the display of the information printed on the thermal coating. The PU film can prevent tearing when it is peeled off, which improves the practicality of the protective film. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this utility model, it should be noted that unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0021] Please see Figure 1-4 A PI pressure-sensitive adhesive label includes a substrate 1, a pressure-sensitive adhesive layer 2 disposed on the top of the substrate 1 for adhesive application, and a printing layer 3 disposed on the top of the pressure-sensitive adhesive layer 2 for isolating adhesive objects and for printing patterns or text information.

[0022] like Figure 1-4 As shown, the printing layer 3 includes a release paper 301 adhered to the top of the pressure-sensitive adhesive layer 2. A thermal coating 302 is disposed on the top of the release paper 301, and a protective film 303 is disposed on the top of the thermal coating 302. The thermal coating 302 can form information printing through a chemical reaction by heat or light energy. The thermal coating 302 is disposed at the bottom of the protective film 303, which protects the information on the thermal coating 302 and makes it difficult to scratch off part of the information of the label by rubbing or scratching, thus having a good information protection function.

[0023] like Figure 1-4 As shown, the substrate 1 has a brown surface and a thickness of 65µm. The pressure-sensitive adhesive layer 2 is made of a 20µm thick transparent composite adhesive. The release paper 301 has a white surface and a thickness of 80µm. The transparent white color of the pressure-sensitive adhesive layer 2 and the release paper 301 will not affect the information displayed on the thermal coating 302.

[0024] like Figure 1-4As shown, the thermal coating 302 is prepared using a water-based coating and contains an adhesive. The water-based coating has excellent protective and corrosion-resistant properties, and uses water as a solvent, thus saving a lot of resources.

[0025] like Figure 1-4 As shown, the protective film 303 is made of PU film. The PU film can prevent tearing when it is torn, thus improving the practicality of the protective film 303.

[0026] Working principle: During use, the thermal coating 302 can form information printing through a chemical reaction using heat or light energy. The thermal coating 302 is located at the bottom of the protective film 303, which protects the information on the thermal coating 302. It is difficult to scratch off part of the information on the label by rubbing or scraping, thus providing good information protection. The pressure-sensitive adhesive layer 2 and the release paper 301 are transparent white and will not affect the display of the information printed on the thermal coating 302. The PU film can prevent tearing when peeling, improving the practicality of the protective film 303.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
