Description

Technical Field

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

[0002] Self-adhesive labels are a type of functional label material with self-adhesion. They consist of three layers: a face stock, adhesive, and a backing paper. To use them, simply peel off the backing paper and apply the label directly; no additional adhesive or wetting is required. The face stock can be made of paper, film, or special materials to meet different printing and durability requirements. The adhesive layer typically uses pressure-sensitive adhesive to achieve its instant-on-adhesion characteristic, while the silicone backing paper ensures that the labels will not accidentally stick together during storage. However, existing self-adhesive labels still suffer from poor tear resistance, low strength, and susceptibility to accidental damage, leading to resource waste.

[0003] Therefore, it is essential to invent a tear-resistant self-adhesive label. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a tear-resistant self-adhesive label, solving the issues of poor tear resistance, low strength, and susceptibility to accidental damage leading to resource waste inherent in existing self-adhesive labels. A tear-resistant self-adhesive label includes a tear-resistant intermediate layer, a lower support layer, an information layer, a protective film, and an adhesive layer. The tear-resistant intermediate layer is fixedly mounted on the surface of the lower support layer, and the information layer is also fixedly mounted on the surface of the tear-resistant intermediate layer. The protective film is adhered to the surface of the information layer. The adhesive layer is coated on the bottom of the lower support layer.

[0005] The tear-resistant intermediate layer includes a reinforcing edge skeleton, a reinforcing edge seal, and an intermediate filler sheet. The reinforcing edge seal is adhered to the outermost side of the surface of the lower support layer, and the reinforcing edge skeleton is adhered to the surface of the lower support layer. The reinforcing edge skeleton is located inside the reinforcing edge seal, and the intermediate filler sheet is adhered to the surface of the lower support layer, with the intermediate filler sheet located inside the reinforcing edge skeleton.

[0006] The reinforcing skeleton inside the tear-resistant interlayer is made of a grid-like plastic sheet, and the grid shape is formed by stamping. The interior of the reinforcing skeleton has a rectangular opening to accommodate the intermediate filling sheet. The reinforcing edge seal is made of a frame-like plastic sheet, and the center of the reinforcing edge seal has a rectangular opening that can accommodate the reinforcing skeleton. The intermediate filling sheet is a piece of paper with the same thickness as the reinforcing skeleton and the reinforcing edge seal, and the intermediate filling sheet can fill the rectangular opening in the center of the reinforcing skeleton. The four sides of the reinforcing edge seal are bent outward to form four sets of arc-shaped edge seals.

[0007] The lower support layer and information layer are made of two pieces of paper, and the tear-resistant intermediate layer is added inside the lower support layer and information layer. The four sides of the lower support layer and information layer are bent outward to form four sets of arc-shaped sealing edges. The arc-shaped sealing edges of the lower support layer and information layer are consistent with those of the tear-resistant intermediate layer. The information layer is printed with the information on the label.

[0008] Compared with the prior art, the present invention has the following beneficial effects: The tear-resistant middle layer of this invention features a multi-layered protective system. This system consists of a grid-like plastic sheet that reinforces the side skeleton to provide axial tensile strength, a frame-like plastic sheet that strengthens the sealing edge to enhance edge tear resistance, and a middle filling sheet that fills the grid gaps and disperses stress. The sandwich structure formed by this layer, the lower support layer, and the information layer, combined with the arc-shaped sealing edge design that bends simultaneously on all four sides, effectively prevents delamination and edge-initiated tearing. This allows the label to maintain flexibility while possessing excellent tear resistance, making it suitable for demanding applications such as logistics packaging and industrial labeling that require repeated pasting or withstand mechanical stress.

[0009] This invention features a lower support layer and an information layer. The lower support layer serves as the basic support structure for the label, providing a stable substrate for the self-adhesive layer and enhancing overall mechanical strength through its composite with a tear-resistant interlayer. The information layer, acting as a printing carrier, carries graphic and textual information, and its combination with a protective film ensures information durability. By sandwiching the tear-resistant interlayer within the information layer to form a sandwich structure, coupled with a synchronously formed curved edge sealing design, the label maintains its flexibility while significantly improving its resistance to delamination and deformation. This results in a label with excellent adhesive stability and information retention, meeting the application requirements of various harsh environments. Attached Figure Description

[0013] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0014] As attached Figure 1 To be continued Figure 2 As shown.

[0015] This utility model provides a tear-resistant self-adhesive label, comprising a tear-resistant intermediate layer 1, a lower support layer 2, an information layer 3, a protective film 4, and a self-adhesive layer 5, wherein: the tear-resistant intermediate layer 1 is fixedly installed on the surface of the lower support layer 2, and the information layer 3 is fixedly installed on the surface of the tear-resistant intermediate layer 1, and the protective film 4 is attached to the surface of the information layer 3; the self-adhesive layer 5 is coated on the bottom of the lower support layer 2.

[0016] The tear-resistant intermediate layer 1 includes a reinforcing edge skeleton 11, a reinforcing edge seal 12, and an intermediate filler 13. The reinforcing edge seal 12 is attached to the outermost side of the surface of the lower support layer 2, and the reinforcing edge skeleton 11 is attached to the surface of the lower support layer 2. The reinforcing edge skeleton 11 is located inside the reinforcing edge seal 12, and the intermediate filler 13 is attached to the surface of the lower support layer 2. The intermediate filler 13 is located inside the reinforcing edge skeleton 11.

[0017] The reinforcing frame 11 inside the tear-resistant interlayer 1 is made of a grid-shaped plastic sheet, and the reinforcing frame 11 is formed into a grid shape by stamping. The interior of the reinforcing frame 11 has a rectangular opening to accommodate the intermediate filling piece 13. The reinforcing edge 12 is made of a frame-shaped plastic sheet, and the center of the reinforcing edge 12 has a rectangular opening that can accommodate the reinforcing frame 11. The intermediate filling piece 13 is made of a piece of paper with the same thickness as the reinforcing frame 11 and the reinforcing edge 12, and the intermediate filling piece 13 can fill the rectangular opening in the center of the reinforcing frame 11. The four sides of the reinforcing edge 12 are bent outward to form four sets of arc-shaped edge seals.

[0018] The lower support layer 2 and the information layer 3 are made of two pieces of paper, and the tear-resistant intermediate layer 1 is added inside the lower support layer 2 and the information layer 3. The four sides of the lower support layer 2 and the information layer 3 are bent outward to form four sets of arc-shaped sealing edges. The arc-shaped sealing edges of the lower support layer 2 and the information layer 3 are consistent with those of the tear-resistant intermediate layer 1. The information on the label is printed on the surface of the information layer 3.

[0019] This tear-resistant self-adhesive label achieves high strength through a five-layer composite structure: the self-adhesive layer 5 provides basic adhesion, the lower support layer 2 serves as a rigid support platform, and the tear-resistant middle layer 1 forms a three-dimensional tear-resistant system through the tensile strength of the reinforced edge skeleton 11, the edge protection of the reinforced edge sealing 12, and the stress dispersion of the middle filler 13. The information layer 3 and the protective film 4 respectively undertake the functions of information carrying and surface protection. When subjected to external force, the arc design of the reinforced edge sealing 12 preferentially disperses edge stress, the grid structure of the reinforced edge skeleton 11 guides the orderly transmission of planar stress, and the elastic modulus gradient design of each layer material forms a multi-level tear-resistant barrier.

[0020] Each structural layer works in close collaboration through a sandwich composite process: the hard-tough combination of the lower support layer 2 and the tear-resistant intermediate layer 1 enhances overall bending resistance; the encapsulation design of the information layer 3 and the protective film 4 ensures information durability; and the simultaneously thermo-pressed curved sealing edge strengthens the interlayer bonding force. This structure gives the label excellent anti-delamination properties, environmental adaptability, and reliability for repeated application, making it particularly suitable for demanding scenarios such as logistics recycling labels and industrial equipment markings that require mechanical friction and repeated peeling and reapplying, extending its lifespan by more than three times compared to traditional labels.

[0021] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
