Abstract (en)
A sealing bag with a chuck capable of surely enhancing an easy-to-unseal property of the sealing bag without increasing the size of the chuck and an entire bag and without causing dissolution, flatness and the like at projected parts at the time of bag-making. The sealing bag comprises a bag body 1 having an opening part 1a at one end, a chuck 10 having a pair of tapes 11a and 11b thermally fused near the opening part of the bag body 1 and opposed to each other along the opening part 1a and a pair of female and male clamping devices 12a and 12b formed on the opposed faces of the pair of tapes 11 and disengageably clamped along the opening part 1a to seal the bag body 1, and a pair of projected parts 20a, 20b formed in a pair of projected lines at the bag body opening side end edge part of the pair of tapes 11a and 11b and integrally projected to the inner and outer surface sides of the bag body 1a, wherein the pair of tapes 11 are thermally fused to the inner face of the bag body, whereby the projected parts 20a and 20b are positioned on the inside of the opening edge part of the bag body 1 and the projected parts 20a, 20b are not thermally fused to the inner face of the bag body 1. <IMAGE>
