摘要： To provide: a reclosable tape that can be manufactured easily and stably, exhibit excellent adhesion strength regardless of a material type of a sealant layer (innermost layer) of a base material film of a bag body and good formability of an engaging portion in manufacturing; and a packaging bag with the reclosable tape. The reclosable tape 1 including a male member 11 and a female member 12 and the packaging bag with the reclosable tape are so arranged that: a belt-shaped base 13 of the reclosable tape 1 includes a seal portion 14 and a base portion 15; a resin forming the base portion 15 has a melting point higher than that of a resin forming the seal portion 14; and the resin forming the seal portion 14 contains 50 mass % or more of a metallocene-type linear-low-density polyethylene having density of 920 kg/m3 or lower, melt flow rate of 5.0 g/10 min or lower.
