Description

Technical Field

[0001] This utility model relates to label paper, and more particularly to an easy-tear label paper structure. Background Technology

[0002] Chinese Patent Publication No. CN213037702U discloses a noise-reducing label paper, the structure of which typically includes a label face paper layer, a sound-absorbing layer, a pressure-sensitive adhesive layer, and a release paper layer. This technical solution effectively achieves noise reduction through the sound-absorbing layer; simultaneously, for electronic and electrical applications, the label also has flame-retardant properties, significantly improving the safety of the label paper. This label structure demonstrates positive technical effects in noise reduction and safety protection.

[0003] However, the noise-reducing label paper is tightly bonded to the release paper via a pressure-sensitive adhesive layer. The strong adhesion of the pressure-sensitive adhesive layer makes it difficult for users to easily lift the edges of the label paper with their fingers when preparing to apply it, which greatly increases the difficulty of separating the label from the release paper and reduces its ease of use. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an easy-tear label paper structure to facilitate separation from the release paper layer.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: an easy-tear label paper structure, including a printing layer, a sound-absorbing layer, and a release paper layer. One side of the sound-absorbing layer is coated with an adhesive layer, which is adhered to the release paper layer. The other side of the sound-absorbing layer is fixedly connected to the printing layer. The release paper layer has a U-shaped line and an easy-tear line. The U-shaped line is arranged around the adhesive layer. There is a non-adhesive area between the edge of the adhesive layer and the U-shaped line. The two ends of the easy-tear line are connected to the two ends of the U-shaped line. Part of the easy-tear line is located directly below the adhesive layer. The U-shaped line and the easy-tear line form a pressing area.

[0006] To achieve the above technical solution, U-shaped lines and easy-tear lines are created on the release paper layer, defining a pressing area and a non-adhesive area. In actual operation, when external force is applied to the pressing area, the release paper layer will controllably separate along the preset U-shaped lines and easy-tear lines. This allows the label portion corresponding to the pressing area to easily detach partially from the release paper layer, exposing an easily grippable corner with an adhesive layer. While holding this corner with one hand or adhering it to another object, the other hand can easily remove the non-adhesive area. This effectively overcomes the difficulty of peeling off due to strong adhesive layers, greatly optimizing the label separation experience and improving ease of use.

[0007] As a preferred embodiment of this utility model, the release paper layer is provided with a pull-out section, the fixed end of the pull-out section is fixedly connected to the side of the release paper layer opposite to the adhesive layer, the fixed end of the pull-out section is close to the tear line and located inside the pressing area, and the gripping end of the pull-out section extends away from the adhesive layer.

[0008] To achieve the above technical solution, during operation, after the label, along with the release liner attached to it, is adhered to the target object through its exposed adhesive layer, the user can hold the gripping end of the extraction section. By applying pulling force to the gripping end, the release liner in the press area can be peeled off from the back of the attached label. This provides a clear removal grip, solving the problem of difficulty in removing residual release liner after label application.

[0009] As a preferred embodiment of this utility model, a limiting groove is provided on the glue-free area. The limiting groove is located at the end of the adhesive layer away from the easy-tear line. The limiting groove penetrates the upper surface and the lower surface of the pressing area. The gripping end of the extraction section passes through the limiting groove.

[0010] To achieve the above technical solution, a through-hole limiting groove is created in the glue-free area of ​​the pressing zone, through which the gripping end of the extraction section extends. When the user pulls the gripping end to remove the release paper from the pressing zone, this limiting groove plays a crucial guiding and positioning role. It constrains the movement trajectory of the extraction section, ensuring that the pulling force is applied at the predetermined position and guiding it to pass through stably. This measure effectively prevents the extraction section from shifting or tearing under force, ensuring that the pressing zone can smoothly separate along the designed path, significantly improving the accuracy and reliability of the removal operation.

[0011] As a preferred embodiment of this utility model, the gripping end of the extraction section is provided with an anti-slip groove, and a plurality of the anti-slip grooves are arranged along the length direction of the gripping end.

[0012] To achieve the above technical solution, multiple anti-slip grooves are provided on the surface of the grip end, significantly increasing the static friction between the operator's fingers and the grip end. This design ensures a stable grip during the final tearing action of the release paper in the pressing area, effectively transmitting tension and preventing slippage even when the user is wearing gloves or has wet hands.

[0013] In a preferred embodiment of this invention, the sound-absorbing layer comprises a polypropylene fiber layer.

[0014] To achieve the above technical solution, the core functional material of the sound-absorbing layer was identified. Using a polypropylene fiber layer as the sound-absorbing layer leverages the excellent acoustic properties inherent in the material's porous fiber structure. When sound waves penetrate this layer, the sound energy is reflected, rubbed, and vibrates within the fiber gaps, thus being efficiently absorbed and converted into heat energy for dissipation.

[0015] In a preferred embodiment of this utility model, the adhesive layer includes a pressure-sensitive adhesive layer.

[0016] To achieve the above technical solution, a pressure-sensitive adhesive layer is used, which allows the label to be applied without heating or solvent activation. Simply by applying appropriate pressure, the adhesive layer can form a strong and lasting bond with the surface of the target object.

[0017] In a preferred embodiment of this invention, the printed layer includes a PET film layer.

[0018] The above technical solution utilizes a PET film layer as the printing layer, taking advantage of the excellent physical and chemical stability of PET material. This material possesses high mechanical strength, wear resistance, high temperature resistance, and chemical corrosion resistance, while also exhibiting excellent printability. This ensures that the graphic information on the label remains clearly legible for a long time in electronic and electrical application environments, and provides robust protection for the underlying sound-absorbing layer and other functional structures, guaranteeing the overall durability and functional stability of the label.

[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered.

[0022] An easy-tear label paper structure includes a printing layer 1, a sound-absorbing layer 2, and a release paper layer 4.

[0023] An adhesive layer 3 is coated on one side of the sound-absorbing layer 2 and adheres to the release paper layer 4. The other side of the sound-absorbing layer 2 is fixedly connected to the printing layer 1.

[0024] The cross-sections of the printing layer 1, adhesive layer 3, and sound-absorbing layer 2 are all square, and the projected areas of the adhesive layer 3, printing layer 1, and sound-absorbing layer 2 on the release paper layer 4 are equal.

[0025] Printed layer 1 is a PET film layer; sound-absorbing layer 2 is a polypropylene fiber layer; adhesive layer 3 is a pressure-sensitive adhesive layer; release paper layer 4 is a glassine release paper layer 4.

[0026] A U-shaped line 5 and an easy-tear line 6 are formed on the release paper layer 4. The U-shaped line 5 surrounds the adhesive layer 3, and there is a non-adhesive area 7 between the edge of the adhesive layer 3 and the U-shaped line 5. The two ends of the easy-tear line 6 are connected to the two ends of the U-shaped line 5. Part of the easy-tear line 6 is located directly below the adhesive layer 3, forming a pressing area 8 between the U-shaped line 5 and the easy-tear line 6.

[0027] A long strip-shaped extraction section 9 is provided on the release paper layer 4. The fixed end 10 of the extraction section 9 is fixedly connected to the side of the release paper layer 4 opposite to the adhesive layer 3. The fixed end 10 of the extraction section 9 is close to the easy-tear line 6 and located inside the pressing area 8.

[0028] A limiting groove 11 is formed in the adhesive-free area 7. The limiting groove 11 is an oblong groove. The limiting groove 11 is located at the end of the adhesive layer 3 away from the easy-tear line 6. The limiting groove 11 penetrates the upper surface and the lower surface of the pressing area 8. The gripping end 12 of the extraction section 9 passes through the limiting groove 11. Anti-slip grooves 13 are formed on the gripping end 12 of the extraction section 9, and multiple anti-slip grooves 13 are arranged along the length direction of the gripping end 12.

[0029] The usage process is as follows: The operator first holds the entire release paper layer 4. Because the release paper layer 4 has pre-set U-shaped lines 5 and easy-tear lines 6, these two lines define the main body of the label and the pressing area 8 on which it is attached. The operator peels the label composite, consisting of the printing layer 1, sound-absorbing layer 2, and adhesive layer 3, from the main body of the release paper layer 4 along the path of the U-shaped lines 5 and easy-tear lines 6 by bending the release paper layer 4 or applying force from its edges.

[0030] After peeling, the operator obtains the label composite. At this point, part of the adhesive layer 3 of the label is exposed, that is, the area other than the original non-adhesive area 7, and is sticky; while the original pressing area 8, as part of the release paper, is still firmly adhered to the corresponding area of ​​the adhesive layer 3, temporarily protecting that part of the adhesive surface from being exposed.

[0031] The operator holds the pre-separated label and, observing the content on the printed layer 1, aligns it with the designated pasting position on the target object. The exposed pressure-sensitive adhesive layer of the label is pressed onto the surface of the target object. Due to the characteristics of the pressure-sensitive adhesive layer, only slight pressure is required for the label to achieve initial, stable adhesion and positioning. At this point, a portion of the label is fixed to the object, while the portion still attached to the release paper in the pressing area 8 remains suspended or not fully adhered. The gripping end 12 of the extraction section 9 is in an operable state.

[0032] The operator locates the gripping end 12 of the extraction section 9 extending from the limiting groove 11. Multiple anti-slip grooves 13 arranged along the length of the gripping end 12 significantly increase finger friction, ensuring the operator can firmly grip the gripping end 12 and prevent slippage during pulling. The operator applies a pulling force to the gripping end 12 in a designated direction. This pulling force is transmitted to its fixed end 10 through the extraction section 9.

[0033] As the pull continues, the release paper of the entire pressing area 8 is completely peeled off from the adhesive layer 3 on the back of the label.

[0034] This structural layout offers mechanical advantages. Because the limiting groove 11 is located at the end of the adhesive layer 3 furthest from the tear line 6, the force applied by the operator when pulling the gripping end 12 is directed away from the initial adhesive interface between the label and the object. This ensures that the tearing force is precisely concentrated on the release paper itself in the pressing area 8, without generating peeling force or shear stress on the already attached label body.

[0035] After the release paper in pressing area 8 is removed, the pressure-sensitive adhesive layer underneath is fully exposed. The operator presses this area to firmly adhere the remaining part of the label to the surface of the target object.

[0036] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
