         7 . An aggregate packaging body comprising:
 a plurality of individual packaging bodies in which packaged bodies are housed;   a gusseted packaging bag formed using a tubular film, the gusseted packaging bag including a gusset part obtained by folding a part of the tubular film into a gusset shape and a seal part obtained by sealing both end portions of the tubular film;   a notch part for opening formed in the gusseted packaging bag,   the plurality of individual packaging bodies being stacked in a vertical direction and housed in the gusseted packaging bag,   wherein the gusseted packaging bag has a top surface provided in an upper part in the vertical direction, a front surface provided in a front part in a front-rear direction intersecting the vertical direction, continuous with the top surface, and included in the gusset part, and a pair of side surfaces which faces each other in a left-right direction intersecting the vertical direction and the front-rear direction, is continuous with the top surface, and is included in the seal part,   the notch part is configured by a slit formed on the front surface to extend in the left-right direction,   the slit is disposed between the center part of the front surface in the vertical direction and the top surface, and   a length of the slit is shorter than a width of the front surface in the left-right direction.   
     
     
         8 . The aggregate packaging body according to  claim 7 , wherein the slit is disposed between a center part of the front surface in the left-right direction and one end portion of the front surface in the left-right direction. 
     
     
         9 . The aggregate packaging body according to  claim 7 , wherein the slit is disposed near the top surface. 
     
     
         10 . The aggregate packaging body according to  claim 7 , wherein the slit is disposed near the center part of the front surface in the vertical direction. 
     
     
         11 . A gusseted packaging bag of the aggregate packaging body according to  claim 7 , the gusseted packaging bag comprising:
 the gusset part;   the seal part; and   the notch part.   
     
     
         12 . A production method for the gusseted packaging bag according to  claim 11 , the method comprising;
 a tubular film forming process of forming a raw film into a tubular shape to form the tubular film;   a gusset forming process of folding the tubular film into a gusset shape to form a gusset-shaped sheet; and   a slit forming process of forming the slit in the gusset part,   wherein the slit forming process is performed before the gusset forming process.   
     
     
         13 . The aggregate packaging body according to  claim 8 , wherein the slit is disposed near the top surface. 
     
     
         14 . The aggregate packaging body according to  claim 8 , wherein the slit is disposed near the center part of the front surface in the vertical direction. 
     
     
         15 . The aggregate packaging body according to  claim 9 , wherein the slit is disposed near the center part of the front surface in the vertical direction. 
     
     
         16 . A gusseted packaging bag of the aggregate packaging body according to  claim 8 , the gusseted packaging bag comprising:
 the gusset part;   the seal part; and   the notch part.   
     
     
         17 . A gusseted packaging bag of the aggregate packaging body according to  claim 9 , the gusseted packaging bag comprising:
