Problems solved by technology
[0012] The bag body with the slider chuck disclosed in Patent Document 3, which has the function of preventing unauthorized opening, cannot be mechanically produced continuously, and there is a problem of poor industrial production efficiency.
[0013] In addition, in the bag body of Patent Document 3, when the label is only attached to a part of the chuck in the longitudinal direction, there is a disadvantage that it is impossible to tell whether the part where the label is not attached has been opened illegally (unsealed by hand without moving the slider)

Embodiment Construction
[0042] figure 1 A perspective view showing an embodiment of the present invention. exist figure 1 In the process, the left and right ends and the bottom of two plastic films 2 and 3 are heat-sealed 7 and 8 to form a bag 1 . At the opening of the bag 1 upper end, a strip-shaped plastic clamp 5 is provided, and a slide block 6 is installed on the plastic clamp 5 .
[0043] The strip-shaped plastic chuck 5 is constituted by a pair of strips, and has a male-female engaging portion (see Figure 4 , Figure 5 ).
[0044] The slider 6 slides along the plastic clamp 5 to open and close the engaging part of the plastic clamp 5 . That is, when slide block 6 is positioned at one ( figure 1 Middle right) end 71 (closed end), the engaging part of the plastic chuck 5 is fully closed, when located at the other ( figure 1 When the end 711 (opening end) is left in the center, the engaging part is fully opened.
