Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of adhesive tapes, in particular to a high-strength hot-melt adhesive tape for packaging. Background Art
[0002] The existing adhesive tape is mainly based on polypropylene film, and hot melt adhesive is coated on the surface of the polypropylene film. During the gluing process, a glue layer detection unit is arranged at the tail end to detect the uniformity of the glue layer. If the glue layer is not uniform enough, the glue output needs to be adjusted accordingly. The hot melt adhesive layer of the tape is cooled and formed by a cooling roller unit, and finally the finished tape is obtained by slitting.
[0003] The adhesive tape used for packaging has high performance requirements for strength and tensile strength, but the current adhesive tape only relies on polypropylene film to provide strength and tensile strength, which is insufficient and prone to deformation and breakage, thus affecting the packaging effect and packaging quality. Therefore, designing a higher strength adhesive tape is a problem that needs to be solved by the staff in this field. Utility Model Content
[0004] The purpose of the utility model is to provide a high-strength hot-melt adhesive tape for packaging. The tensile strength and tensile strength of the adhesive tape can be improved by adding a reinforcing layer of glass fiber material. At the same time, by arranging convex film layers on the upper and lower surfaces of the reinforcing layer, the convex parts of the convex film layers are embedded in the gaps of the reinforcing layers, and the mutual misalignment can greatly improve the tensile strength and tensile strength of the adhesive tape.

[0006] The utility model is a high-strength hot-melt adhesive tape for packaging, comprising a base layer, a surface layer and a reinforcement layer, wherein the lower surface of the base layer is compounded with a hot-melt adhesive layer;
[0007] The reinforcement layer is a glass fiber cloth layer or a glass fiber mesh layer;
[0008] The upper surface and the lower surface of the reinforcing layer are both compounded with a convex film layer, a surface of the convex film layer is provided with a plurality of evenly distributed convex parts, and the convex parts of the convex film layer are embedded in the gaps of the reinforcing layer;
[0009] The plurality of convex portions on the two convex film layers are staggered and distributed, and the convex portion on one convex film layer is in contact with the surface of the other convex film layer close to the reinforcement layer;
[0010] The surface layer is compounded on the convex film layer on the upper surface of the reinforcement layer, and the base layer is compounded on the lower surface of the convex film layer on the lower surface of the reinforcement layer.
[0011] Furthermore, a surface of the two convex film layers away from the reinforcement layer is formed into a flat surface through the convex part.
[0012] Furthermore, the convex film layer and the reinforcement layer are compounded by colloid, and part of the colloid is filled in the gaps of the reinforcement layer.
[0013] Furthermore, the surface layer is a wear-resistant film layer.
[0014] Furthermore, the base layer is a polypropylene film layer.
[0015] The utility model has the following beneficial effects:
[0016] The utility model can improve the tensile strength and tensile capacity of the adhesive tape by adding a reinforcing layer of glass fiber material, and at the same time, by arranging the convex film layers on the upper and lower surfaces of the reinforcing layer, the convex parts of the convex film layers are embedded in the gaps of the reinforcing layers, and the mutual misalignment can greatly improve the tensile strength and tensile capacity of the adhesive tape, and at the same time, the convex parts of the convex film layers can also play a supporting and cushioning role, ensuring that the surface of the convex film layer away from the reinforcing layer is in a flat surface, which is beneficial to the arrangement of the hot melt adhesive layer, while ensuring the uniformity of the adhesive, and facilitating the precise detection of the adhesive layer on the subsequent adhesive tape, thereby improving the quality of the adhesive layer on the adhesive tape.
