Strapping tape for battery module, manufacturing process of strapping tape and battery module

The invention relates to a strapping tape for a battery module, a manufacturing process of the strapping tape and the battery module, the strapping tape comprises a tape body, and two ends of the tape body are overlapped and welded together to form a rectangular structure so as to be strapped outside a plurality of battery cells of the battery module; the anti-corrosion protection sleeve structure is arranged at the lap welding positions of the two ends of the belt body in a sleeving mode and comprises an outer-layer heat shrink tube and an inner-layer hot melt adhesive layer, and when the anti-corrosion protection sleeve structure is heated, the outer-layer heat shrink tube is heated to shrink so that the inner-layer hot melt adhesive layer can be fused and fixed to the lap welding positions of the two ends of the belt body, and anti-corrosion sealing is formed. The mode that the outer-layer heat shrink tube is matched with the hot melt adhesive can guarantee the reliability of the sealing structure, the out
