[0024] Reference Figure 2 , substrate layer 201 is made of polyurethane foam material.

[0025] Wherein, polyurethane foam material itself has higher strength and toughness, which makes substrate layer 201 made of it not easy to break when subjected to external force stretching, thereby ensuring the overall tensile performance of double-sided adhesive tape, and this feature makes adhesive tape body 2 perform well in application scenarios that need to bear larger tension or shear force.
