Abstract
A bag 1 with a reclosable tape includes a reclosable tape 20 having a male fastener part 21 and a female fastener part 22 attached to one inner surface of a bag body 10, a cut tape 23 provided between mounting base parts 212 and 222 of those fastener parts, and an easily unsealable structure 50 formed on the mounting base part 212 adjacent to the cut tape 23 in an unsealing start part 30 of a side seal part 60 of the bag body. The easily unsealable structure 50 may be formed by: forming a hole portion 50a or a portion formed by a weak line on the mounting base part 212, arranging a thickness of the mounting base part 212 in the unsealing start part 30 so as to be thinner than other portions, or forming a non-adhesive part between the mounting base part 212 and the cut tape 23.
