BRIEF DESCRIPTION OF DRAWINGS

[0014] Figure 1 It is a three-dimensional structure schematic view of the hot melt pressure-sensitive adhesive tape.

[0015] Figure 2 It is a layered structure schematic view of the hot melt pressure-sensitive adhesive tape.

[0016] In the drawing: 1-hot melt pressure-sensitive adhesive tape main body, 11-cloth base layer, 12-main body filling layer, 13-adhesive coating layer, 2-notch, 3-adhesive strip, 4-release film layer. DETAILED DESCRIPTION

[0017] In order to facilitate the understanding of those skilled in the art, the utility model will be further described below in combination with examples and drawings, and the content mentioned in the implementation manner is not a limitation of the utility model. The utility model will be described in detail below in combination with the drawings.

[0018] Please refer to Figures 1-2 A hot melt pressure-sensitive adhesive tape, including hot melt pressure-sensitive adhesive tape main body 1, hot melt pressure-sensitive adhesive tape main body 1 includes cloth base layer 11, main body filling layer 12 and adhesive coating layer 13, cloth base layer 11, main body filling layer 12 and adhesive coating layer 13 are stacked in turn from top to bottom and present layered structure, and cloth base layer 11 is made of gauze.

[0019] A plurality of notches 2 are arranged at both side edges of the hot melt pressure-sensitive adhesive tape main body 1, and the notches 2 are arranged in a linear array structure at both side edges of the hot melt pressure-sensitive adhesive tape main body 1, and a peelable adhesive strip 3 is also arranged at both side edges of the hot melt pressure-sensitive adhesive tape main body 1, and the adhesive strip 3 is attached to the surface of the notch 2.
