A self-adhesive label with physical waterproof function

Abstract

This utility model discloses a self-adhesive label with physical waterproof function, comprising: a self-adhesive label body, the self-adhesive label body including: a base layer, multiple adhesive layers uniformly disposed on one side of the base layer, and a face material assembly disposed on one side of the adhesive layers, the face material assembly being composed of a paper layer, a channel, and a filler adhesive. Through the cooperation between the base layer, adhesive layers, face material assembly, waterproof layer, and display information, it can effectively block water from penetrating to the edge of the paper layer, greatly increasing the difficulty of rainwater completely seeping into the interior of the paper layer, reducing the probability of paper layer delamination during subsequent use, and reducing the possibility of the displayed information falling off the paper layer. Even if water completely penetrates into the interior of the paper layer causing delamination, because the waterproof layer is connected to the adhesive layer through the filler adhesive, it can still prevent the displayed information from falling off to a certain extent, thereby improving the durability of the self-adhesive label.

Description

Technical Field

[0001] This utility model relates to the field of self-adhesive label technology, and in particular to a self-adhesive label with physical waterproof function. Background Technology

[0002] Self-adhesive labels are labels made of paper, film, or other materials with a pressure-sensitive adhesive coating on the back and protected by a release liner. To use them, simply peel off the release liner and stick them directly onto the surface of the object; no additional glue or tools are required. They are widely used in product identification, logistics tracking, asset management, and other fields.

[0003] Currently, self-adhesive labels on the market consist of a paper layer, an adhesive layer, and a release layer. To improve the waterproof performance of the paper layer, a waterproof layer is usually applied to the surface of the paper layer, which also improves the overall tear resistance of the label, basically meeting people's daily needs.

[0004] However, under certain specific conditions, there are still some minor drawbacks. For example, when the label is used outdoors, although the waterproof layer can protect the surface of the paper layer, some rainwater will come into contact with the edges of the paper layer. Due to the capillary effect of the paper layer (the capillary effect is the phenomenon of liquid spontaneously flowing in thin tubes or porous materials due to the difference between cohesion and adhesion), rainwater can easily completely penetrate into the paper layer. After drying, the paper layer is more likely to delaminate, and the displayed information on the paper layer is prone to falling off. The durability of the self-adhesive label needs to be improved. Therefore, it is necessary to provide a self-adhesive label with physical waterproof function to solve the above technical problems. Utility Model Content

[0005] In order to overcome the defects of the prior art, this utility model provides a self-adhesive label with physical waterproof function, which can greatly increase the difficulty of rainwater completely penetrating into the paper layer, reduce the probability of the paper layer delaminating during subsequent use, and prevent the information displayed on the paper layer from falling off, thereby improving the durability of the self-adhesive label.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A self-adhesive label with physical waterproof function includes: a self-adhesive label body, the self-adhesive label body including: a base layer, a plurality of adhesive layers uniformly disposed on one side of the base layer, a face material assembly disposed on one side of the adhesive layers, the face material assembly being composed of a paper layer, a through groove and a filler adhesive, the paper layer being connected to the adhesive layers, display information being disposed on one side of the paper layer, a waterproof layer being disposed on the side of the display information, a through groove being formed at one edge of the paper layer, and a filler adhesive being disposed inside the through groove.

[0008] Preferably, the number of through slots is one or more, depending on the bonding method of the paper layers.

[0009] Preferably, the bottom end of the paper layer has a protrusion.

[0010] Preferably, an indentation is provided at the top of one side of the protrusion.

[0011] Preferably, both ends of the indentation are provided with tear openings.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) In this utility model, through the cooperation between the base layer, adhesive layer, face material component, waterproof layer and display information, the waterproof layer can protect the surface of the paper layer and effectively prevent external moisture from contacting the display information. The through groove and the filling glue inside it can effectively block the water that penetrates to the edge of the paper layer, greatly increasing the difficulty of rainwater completely penetrating into the paper layer, reducing the probability of the paper layer delaminating during subsequent use, and reducing the situation of the display information falling off the paper layer. Even if the water completely penetrates into the paper layer and causes delamination, the waterproof layer can also prevent the display information of the paper layer from falling off to a certain extent because it is connected to the adhesive layer through the filling glue, thereby improving the durability of the self-adhesive label.

[0014] (2) In this utility model, through the cooperation between the base layer, adhesive layer, face material component, waterproof layer, display information, indentation and tear, the user can apply force to the protrusion during the process of peeling the adhesive layer from the base layer surface. Since there is no adhesive layer between the protrusion and the base layer, the paper layer can be peeled from the base layer surface very easily. During this process, there will be no bending deformation caused by the difficulty in peeling the paper layer, which will lead to the inability to use it normally. After the paper layer is glued to the appropriate position, the user can tear the tear at the tear, so that the protrusion is separated from the paper layer at the indentation, thereby avoiding the protrusion from affecting the overall aesthetics of the self-adhesive label.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0021] Example 1: As Figures 1-4 As shown, this utility model provides a self-adhesive label with physical waterproof function, including: a self-adhesive label body 1, the self-adhesive label body 1 including: a base layer 2, a plurality of adhesive layers 3 evenly provided on one side of the base layer 2, a face material component 4 provided on one side of the adhesive layer 3, the face material component 4 is composed of a paper layer 41, a through groove 42 and a filler adhesive 43, the paper layer 41 is connected to the adhesive layer 3, a display information 6 is provided on one side of the paper layer 41, a waterproof layer 5 is provided on one side of the display information 6, a through groove 42 is opened at one edge of the paper layer 41, and the inside of the through groove 42 is filled with filler adhesive 43.

[0022] In the specific implementation process, it is worth noting that the base layer 2 is glassine paper, which can protect the release paper of the adhesive layer 3 and prevent the labels from sticking together before use. The adhesive layer 3 is made by emulsifying acrylic or polyurethane resin with water as a solvent. It is environmentally friendly, non-toxic, inexpensive, and the glue is non-flammable. It has a wide range of solid content and viscosity, can use high-concentration high-molecular-weight materials, and can control penetration and wetting. Of course, the adhesive layer 3 can also be other adhesive materials that are good at self-adhesive labels. This application does not limit the material of the adhesive layer 3. The description is only for ease of understanding. The paper layer 41 is coated paper, which is used as the paper layer in the self-adhesive label. The display information 6 can be limited according to the customer's needs during actual production. The waterproof layer 5 is a transparent PP film, which can play a role in waterproofing and tear resistance. The filler glue 43 is made of the same material as the adhesive layer 3. The adhesive layer 43 is bonded to the waterproof layer 5.

[0023] Example 2: The number of through slots 42 is determined by the bonding method of the paper layers 41, and may be one or more.

[0024] In practical implementation, it is worth noting that when the paper layer 41 is used vertically, it can be configured as a large through slot 42 (as shown in the instruction manual). Figure 1 As shown), this effectively prevents rainwater from seeping downwards. When the paper layer 41 is laid flat, multiple channels 42 can be provided so that the filling adhesive 43 inside the channels 42 can evenly bond the waterproof layer 5, preventing large-scale peeling of the waterproof layer 5 due to the delamination of the paper layer 41.

[0025] Example 3: The bottom end of the paper layer 41 is provided with a protrusion 44.

[0026] In the specific implementation process, it is worth noting that the protrusion 44 and the paper layer 41 are integrally formed, but the protrusion 44 does not have an adhesive layer 3, which makes it very convenient to peel the paper layer 41 from the surface of the base layer 2.

[0027] Example 4: An indentation 7 is provided on the top of one side of the protrusion 44.

[0028] In the specific implementation process, it is worth noting that during the tearing of the protrusion 44, it will break along the indentation 7. The essence of the breakage at the indentation 7 is the mechanical instability of the paper layer 41 material under the combined effect of geometric defects and stress concentration, along the path of minimum energy consumption.

[0029] Example 5: Both ends of the indentation 7 are provided with tear openings 8.

[0030] In the specific implementation process, it is worth noting that the tear slit 8 is designed so that the user can apply force precisely to both ends of the indentation 7, which can provide some convenience when tearing off the protrusion 44.

[0031] During use, when peeling the adhesive layer 3 from the surface of the base layer 2, the user can apply force to the protrusion 44. Since there is no adhesive layer 3 between the protrusion 44 and the base layer 2, the paper layer 41 can be easily peeled from the surface of the base layer 2. During this process, there will be no bending or deformation caused by the difficulty in peeling the paper layer 41, which would prevent it from being used normally. After the paper layer 41 is glued to the appropriate position, the user can tear at the tear 8, causing the protrusion 44 to separate from the paper layer 41 at the indentation 7, thus avoiding the protrusion 44 affecting the overall aesthetics of the self-adhesive label. During use, the display information 6 on the surface of the paper layer 41 can be seen at the bonding point. During use, the waterproof layer 5 protects the surface of the paper layer 41, effectively preventing external moisture from contacting the display information 6. The channel 42 and the filler 43 inside it effectively block moisture from penetrating to the edge of the paper layer 41, greatly increasing the difficulty for rainwater to completely penetrate into the paper layer, reducing the probability of the paper layer delaminating during subsequent use, and reducing the chance of the display information falling off the paper layer. Even if moisture completely penetrates into the paper layer 41 and causes delamination, the waterproof layer 5 is connected to the adhesive layer 3 through the filler 43, which can also prevent the display information on the paper layer 41 from falling off to a certain extent, thereby improving the durability of the self-adhesive label.

[0032] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
