ABSTRACT:
There is provided a fastener bag capable of improving working efficiency for the filling of inner content and forming a bag cut-starting portion. The bag is formed as gusset-type packaging bag, to which a fastener for freely opening or closing the packaging bag is attached. The fastener has a male portion to which a projected thread is formed and a female portion to which a groove is formed so as to be engaged with the projected thread. Base portions of the male and female portions are attached to an inner surface of one of the flat surface portions or side surface portions so that the projected thread and the groove face each other. A cut-tape for separating the flat surface portion into the male portion side and the female portion side is provided between the base portions.
