         2 . Casing according to  claim 1 , wherein the side panel part is made of one sheet which comprises the two side panels and a linking part between the two side panels linking both side panels one to the other, the side panel part is folded in a U-shape and the linking part forms a bottom of the U, the linking part further comprising two free edges on either side between the two side panels, and a sealing margin along its two free edges, the peripheral free edge of each side panel extending from one free edge of the linking part to the other, and the band being sealed to the sealing margin of both side panels, and to the sealing margin of both free edges of the linking part, forming the flange extending outward. 
     
     
         3 . Casing according to  claim 1 , wherein it comprises an opening system comprising at least one opening and a closing element configured to close the opening. 
     
     
         4 . Casing according to  claim 3 , wherein it comprises a pre-cut line demarcating the closing element and the opening. 
     
     
         5 . Casing according to  claim 4 , wherein at least a part of the pre-cut line is done in the sealing area of the band in which the band is sealed to at least the sealing margin of one side panel. 
     
     
         6 . Casing according to  claim 1 , wherein the flange comprises at least one notch formed in at least a part of the flange surrounding a corner of the casing. 
     
     
         7 . Casing blank to manufacture a casing, the casing blank comprising:
 a side panel part comprising at least two side panels, configured to build two side panels of the casing, each side panel comprising a peripheral free edge and a sealing margin along the peripheral free edge which is configured to be bent outward to form a flange, and   one band, made from one sheet, comprising a sealing area configured to be sealed to at least the sealing margin of both side panels.   
     
     
         8 . Casing blank according to  claim 7 , wherein the side panel part is made of one sheet which comprises the two side panels and a linking part between the two side panels linking both side panels one to the other. 
     
     
         9 . Casing blank according to  claim 7 , wherein it comprises an opening system comprising at least one opening. 
     
     
         10 . Casing blank according to  claim 9 , wherein the opening system further comprises at least a closing element configured to close the opening, and a pre-cut line demarcating the closing element and the opening. 
     
     
         11 . Casing blank according to  claim 10 , wherein at least a part of the pre-cut line is done in the sealing area of the band in which the band is configured to be sealed to at least the sealing margin of one side panel. 
     
     
         12 . Casing blank according to  claim 7 , wherein at least one of the side panels comprises a press-formed line which is parallel to at least one peripheral free edge of the side panel, and which is formed a few millimetres at a distance from the peripheral free edge of the side panel, thus forming the sealing margin between the peripheral free edge and the press-formed line. 
     
     
         13 . Casing blank according to  claim 7 , wherein at least one of the sealing margin of one side panel or the sealing area of the band comprises at least one notch in at least a part configured to surround a corner. 
     
     
         14 . Method for manufacturing a casing comprising steps of:
 providing a blank casing for transporting food or beverage product, the casing comprising:   a side panel part comprising at least two side panels, each side panel comprising a peripheral free edge and a sealing margin along the peripheral free edge,   one band, made from one sheet, and comprising a sealing area, and   the sealing area of the band being sealed to the sealing margin of both side panels, forming a flange extending outward;   sealing a sealing area of the band on at least a part of the sealing margin of a first of the two side panels, forming at least a part of the flange extending outward;   placing product on the first side panel; and   sealing a sealing area of the band along the sealing margin of a second of the two side panels, finalizing forming the flange extending outward.   
     
     
         15 . Method according to  claim 14 , comprising a step of folding a sealing margin of at least one of the side panels along a corresponding press-formed line which is parallel to at least a part of the peripheral free edge of the side panel in order to form at least a part of the flange. 
     
     
         16 . Method according to  claim 14 , further comprising steps of:
 folding the side panel part made of one sheet into a U about the linking part;   sealing the linking part of the side panel part to at least one end of the band; and   completing sealing a sealing area of the band along a sealing margin of the side panel part.
