 a discharge film ( 210 ) configured to cover the opening ( 130 ) and the periphery of the opening ( 130 ); and 
 an adhesive surface ( 220 ) disposed on a surface of the discharge film and configure to directly contact the zipper bag body, the adhesive surface having a hollow portion at a center portion thereof, the hollow portion corresponding to the opening ( 130 ) when the adhesive surface is adhered to the zipper bag body, 
 wherein an adhesive is applied on the adhesive surface except for the hollow portion, and when the discharge film is detached from the zipper bag body, the adhesive is disposed on the discharge film. 
   
     
     
         2 . (canceled) 
     
     
         3 . The zipper bag of  claim 1 , wherein the discharge portion has a rectangular shape and further includes a guide knob ( 211 ) formed in a band shape at a center portion of a first edge of the discharge portion ( 200 ) and protruding from the first edge in a lateral direction. 
     
     
         4 . The zipper bag of  claim 3 , wherein a fixing portion ( 240 ) adhered and fixed to the zipper bag is further formed at a second edge of the discharge portion ( 200 ), and
 the fixing portion ( 240 ) fixes the discharge portion ( 200 ) to the zipper bag body so that the discharge portion ( 200 ) does not deviate from the initial position on the zipper bag body when the user detaches a part of the discharge portion ( 200 ) from the zipper bag body by using the guide knob ( 211 ).   
     
     
         5 - 6 . (canceled) 
     
     
         7 . The zipper bag of  claim 1 , wherein the opening has an I-shape or a zig zag shape. 
     
     
         8 . A zipper bag for easy air discharge of which one side is configured to be opened and closed to store contents in the zipper bag, the zipper bag comprising:
 a discharge film configured to attached to and detached from a zipper bag body by an adhesive layer,   wherein the adhesive layer is formed on a surface of the discharge film and configure to directly contact the zipper bag body, the adhesive layer including:   a first adhesive applied on substantially whole area of the surface of the discharge film except for a center portion of the discharge film; and
 a second adhesive applied at the center portion of the surface of the discharge film, the second adhesive having a stronger adhesion strength than that of the first adhesive, 
 wherein when the discharge film is detached from the zipper bag body, the second adhesive makes an opening at the zipper bag body by cutting a portion corresponding to the second adhesive out of the zipper bag body, and the discharge film is configured to be attached to and detached from the zipper bag body by the first adhesive of the adhesive layer, and 
   wherein when the discharge film is detached from the zipper bag body, the adhesive layer is disposed on the surface of the discharge film.   
     
     
         9 . The zipper bag of  claim 8 , wherein the discharge film has a rectangular shape and includes a guide knob formed in a band shape at a center portion of a first edge of the discharge film and protruding from the first edge in a lateral direction. 
     
     
         10 . The zipper bag of  claim 9 , wherein the discharge film further includes a fixing portion formed at a second edge of the discharge film to fix the discharge film to the zipper bag body such that the discharge portion does not deviate from the initial position on the zipper bag body when the user detaches a part of the discharge film from the zipper bag body by using the guide knob. 
     
     
         11 . The zipper bag of  claim 8 , wherein the opening has an I-shape or a zig zag shape. 
     
     
         12 . A zipper bag for easy air discharge, comprising:
 an opening formed at a zipper bag body such that an inner space of the zipper bag communicates with an outside of the zipper bag; and   a discharge film configured to cover the opening and a periphery of the opening and attached to and detached from the zipper bag body by an adhesive layer,   wherein the adhesive layer is formed on a surface of the discharge film and configure to directly contact the zipper bag body, the adhesive layer including:
 a hollow portion at a center portion of the adhesive layer, the hollow portion corresponding to a shape of the opening; and 
 a adhesive applied on substantially whole area of the surface of the discharge film except for the hollow portion and a boundary portion of the discharge film, and 
   wherein when the discharge film is detached from the zipper bag body, the adhesive layer is disposed on the surface of the discharge film.   
     
     
         13 . The zipper bag of  claim 12 , wherein the discharge film has a rectangular shape and includes a guide knob formed in a band shape at a center portion of a first edge of the discharge film and protruding from the first edge in a lateral direction. 
     
     
         14 . The zipper bag of  claim 13 , wherein the discharge film further includes a fixing portion formed at the boundary portion of a second edge of the discharge film to fix the discharge film to the zipper bag body such that the discharge portion does not deviate from the initial position on the zipper bag body when the user detaches a part of the discharge film from the zipper bag body by using the guide knob.
