 side planes ( 104 ), 
 lateral sealing clamp units ( 105 ), 
 
 wherein the blades ( 102 ), when ejected, are laterally ejected from the plunger body, thereby guiding areas of the blank to be sealed together into the lateral sealing clamp units ( 105 ) of the forming body ( 103 ), 
 an end sealing clamp unit ( 106 ), to close the preform to result in a packaging sachet, 
 a forming table ( 107 ), comprising an opening ( 108 ) providing access for the plunger body ( 101 ) to the forming body ( 103 ), 
 a filling unit ( 109 ). 
   
     
     
         2 . Apparatus according to  claim 1 , wherein a cross section of the plunger body ( 101 ) has three corners. 
     
     
         3 . Apparatus according to  claim 1 , wherein the side ( 113 ) of the plunger body directed to the forming body is oblique relative to the length of the plunger body ( 101 ). 
     
     
         4 . Apparatus according to  claim 1 , wherein the side of the plunger body directed to the forming body is oblique relative to the length of the plunger body with an angle α, and wherein the forming table is positioned oblique relative to the length of the plunger body with an angle β, and wherein the angles α and β are the same. 
     
     
         5 . Apparatus according to  claim 1 , wherein at least one of the side planes ( 104 ) is removable from the forming body, and at least one of side planes ( 104 ) is not removable from the forming body ( 103 ). 
     
     
         6 . Apparatus according to  claim 5 , wherein the apparatus further comprises a rotation table ( 110 ) accommodating more than one forming body ( 103 ), preferably two, to which rotation table at least one, preferably two, non-removable side plane of the forming bodies ( 103 ) are connected. 
     
     
         7 . Apparatus according to  claim 1 , wherein the forming body ( 103 ) further comprises an end sealing clamp unit ( 106 ), which preferably is located at the upper part of the forming body ( 103 ) at non-removable side planes. 
     
     
         8 . Apparatus according to  claim 1 , wherein the plunger body ( 101 ) comprises means to allow air to pass. 
     
     
         9 . Apparatus according to  claim 1 , wherein the apparatus comprises a wedge  114 . 
     
     
         10 . A process for the manufacturing of a packaging sachet containing a product, the process comprising the steps of:
 a) Positioning a blank comprising areas to form a seal rim on a forming table ( 107 ),   b) Moving a plunger body ( 101 ) comprising laterally ejectable blades ( 102 ) into a forming body ( 103 ) comprising side planes ( 104 ) and lateral sealing clamp units ( 105 ), wherein the ejectable blades ( 102 ) are laterally ejected from the plunger body, thereby guiding areas of the blank to be sealed together into the lateral sealing clamp units ( 105 ) of the forming body ( 103 ), the areas remaining separated from each other by a blade ( 102 ).   c) Retracting the laterally ejectable blades ( 102 ) of the plunger body ( 101 ) into the plunger body,   d) Sealing the areas of the blank present in the lateral sealing clamp units ( 105 ), thereby providing a preform,   e) Removing the plunger body ( 101 ) from the preform,   f) Filling the preform with product,   g) Closing the preform by sealing via an end sealing clamp unit ( 106 ), thereby providing a packaging sachet comprising product,   h) Releasing the sachet.   
     
     
         11 . Process according to  claim 10 , wherein the process further comprises the steps of:
 after step e), releasing at least some of the lateral clamp seal units ( 105 ),   detaching at least part of the forming body ( 103 ) from the preform ( 103 ), to allow transportation of the preform to a filling unit ( 109 ),   after step h) returning the detached part of the forming body back in its original position, thereby reassembling a forming body ( 103 ).   
     
     
         12 . Process according to  claim 11 , wherein the transportation of the preform to a filling unit occurs via rotation of a rotation table ( 110 ) to which the preform is connected via at least one lateral sealing clam unit ( 105 ). 
     
     
         13 . Process according to  claim 10 , wherein filling in step f) is carried out via a filling unit ( 109 ), preferably a filling nozzle, preferably via bottom up filling. 
     
     
         14 . Process according to  claim 10 , wherein before closing step g), a wedge guides a part of the preform into the direction of the end sealing clamp unit, in the direction parallel to the end sealing clamp unit ( 106 ).
