Description

Technical Field

[0001] This utility model relates to the field of self-adhesive label technology, specifically to a tear-resistant self-adhesive label. Background Technology

[0002] Self-adhesive labels, as a convenient identification medium, have been widely used in many fields such as food, medicine, electronics, logistics, and chemicals due to their easy application, low cost, and wide range of applications. They are firmly attached to the surface of the object by adhesive, realizing functions such as information identification, product traceability, and anti-counterfeiting.

[0003] In practical use, traditional self-adhesive labels often suffer from insufficient tear resistance. This is mainly because the face material of existing self-adhesive labels is mostly made of ordinary paper, film, and other materials, which have low tensile and tear strength and lack effective stress dispersion structures. When the label is subjected to lateral or longitudinal external forces, the stress tends to concentrate locally, causing the label to tear from the edge or weak point. Therefore, a new technical solution is proposed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to provide a tear-resistant self-adhesive label, which solves the problem mentioned in the background art that traditional self-adhesive labels mostly use ordinary paper, film and other materials, lack an effective stress dispersion structure, and when the label is subjected to horizontal or vertical external force, the stress is easily concentrated locally, causing the label to tear from the edge or weak point.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a tear-resistant self-adhesive label, comprising a rubber frame, wherein the interior of the rubber frame is provided with basalt fibers and polyester fibers, the fiber orientations of the basalt fibers and polyester fibers are perpendicular to each other to form an alternating grid structure, and the strip-shaped gaps in the fiber orientations of the basalt fibers and polyester fibers are filled with a number of plastic strips.

[0006] In this technical solution, basalt fibers and polyester fibers are interwoven. By utilizing the high strength of the fiber materials, the stress can be dispersed along the multi-directional fiber path when the label is subjected to tension, avoiding local tearing caused by stress concentration. At the same time, multiple plastic strips are set up to complement the fiber mesh structure, further enhancing the label's ability to resist tension in both the horizontal and vertical directions. The combination of these factors significantly improves the overall tensile strength of the label.

[0007] Preferably, a polyurethane elastic sticker is fixedly connected to the center of the top of the rubber frame, and an elastic plastic film is pasted on the surface of the polyurethane elastic sticker.

[0008] Preferably, a corrugated layer is provided below the basalt fiber and polyester fiber, the corrugated layer being made of polyethylene blend, and the corrugated layer being located inside the rubber frame and bonded to the rubber frame.

[0009] Preferably, the rubber frame has a memory metal strip inside, which surrounds the inside of the rubber frame.

[0010] Preferably, a polyester film is adhered to the bottom of the rubber frame, and the bottom of the polyester film is provided with non-adhesive and covered with non-adhesive paper.

[0011] Preferably, the plastic strips inside the basalt fiber and polyester fiber are perpendicular to each other and equidistantly distributed, and the interior of the plastic strips is hollow and filled with glue.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model features a rubber frame on the outside of the entire label body to protect the edges. It also incorporates overlapping basalt fibers and polyester fibers, utilizing the high strength of the fiber materials to disperse stress along multi-directional fiber paths when the label is subjected to tension, thus avoiding localized tearing caused by stress concentration. In addition, multiple plastic strips complement the fiber mesh structure, further enhancing the label's ability to resist tension in both the horizontal and vertical directions. The combined effect of these multiple elements significantly improves the overall tensile strength of the label.

[0013] 2. This utility model incorporates a memory metal strip inside the rubber frame, which allows the material to recover its original shape to a certain extent after being stretched. Meanwhile, the plastic strip breaks when stretched excessively, allowing the internal adhesive to flow out, seep into the crack, and solidify rapidly. This provides a certain degree of sealing and repair to the crack, delaying further tearing and enhancing the label's tear resistance and lifespan. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0017] A tear-resistant self-adhesive label, see [link / reference] Figures 1 to 3 It includes a rubber frame 2, inside which are basalt fibers 3 and polyester fibers 4. The fibers of the basalt fibers 3 and polyester fibers 4 are perpendicular to each other to form an alternating grid structure, and the strip-shaped gaps of the fibers of the basalt fibers 3 and polyester fibers 4 are filled with several plastic strips 5.

[0018] In the above technical solution, the rubber frame 2 provides a supporting frame for the entire label, and its elastic material can absorb external impact force; the grid structure formed by the vertical interweaving of basalt fiber 3 and polyester fiber 4 can disperse the local tensile force to the entire fiber network. When the label is subjected to horizontal or vertical tension, the two types of fibers bear the stress in the corresponding direction respectively; the plastic strip 5 fills the fiber gaps and forms a complementary structure with the fiber grid, further enhancing the label's ability to resist tension in the horizontal and vertical directions. The combination of multiple factors significantly improves the overall tensile strength of the label.

[0019] Specifically, such as Figure 3 As shown, the plastic strips 5 inside the basalt fiber 3 and polyester fiber 4 are perpendicular to each other and equidistantly distributed. The inside of the plastic strip 5 is hollow and filled with glue 501. When the local stress on the label exceeds the threshold, the plastic strip 5 breaks first to release some stress. At the same time, the glue 501 in the hollow structure is squeezed out and quickly solidifies at the crack to form an adhesive repair layer, which delays the further expansion of the tear and further improves the tear resistance and service life of the label.

[0020] Furthermore, a corrugated layer 6 is provided below the basalt fiber 3 and the polyester fiber 4. The corrugated layer 6 is made of polyethylene blend and is located inside the rubber frame 2 and bonded to the rubber frame 2. As a support layer, the corrugated layer 6 can support the basalt fiber 3 and the polyester fiber 4 above. When subjected to tension, it undergoes elastic deformation, absorbs energy by unfolding, and slows down the transmission speed of stress to the fiber layer.

[0021] The rubber frame 2 has a memory metal strip 202 inside, which surrounds the inside of the rubber frame 2. The memory metal strip 202 is made of nickel-titanium alloy and is pre-made into a ring that matches the rubber frame 2 during label production. When the label is stretched and the frame is deformed, the memory metal strip 202 generates recovery stress due to the deformation. After the external force is removed, it drives the rubber frame 2 and the internal fiber layer to return to their original shape.

[0022] It is worth noting that, such as Figure 2 and Figure 3As shown, a polyurethane elastic sticker 101 is fixedly connected to the center of the top of the rubber frame 2. After the surface is coated, it is compatible with various printing methods such as laser printing and thermal transfer, and the text is clear and durable. An elastic plastic film 1 is pasted on the surface of the polyurethane elastic sticker 101, which can protect and cover the surface of the sticker. A polyester film 201 is pasted to the bottom of the rubber frame 2. The bottom of the polyester film 201 is provided with non-adhesive and covered with non-adhesive paper 7. The polyester film 201 is elastic, thus having tensile strength and can deform with the rubber frame 2 above. The non-adhesive at its bottom allows for normal pasting after the non-adhesive paper 7 is peeled off.

[0023] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.
