       8 . Folded-carton package as claimed in  claim 7 , characterized by the fact that the respective at least one weld seam ( 6 ) is located on the related peripheral side of the bottom ( 2 ) or in the immediate vicinity of said peripheral side.  
   
   
       9 . Folded-carton package as claimed in  claim 8 , characterized by the fact that the at least one weld seam ( 6 ) extends over the entire length of the relative peripheral side or over the entire width of the respective material segment ( 5 ) running parallel to this peripheral side.  
   
   
       10 . Method for the manufacture of a folded-carton package for holding a liquid beverage, with a folded-carton package body ( 3 ) made of a weldable flat material having a polygonal cross section and with a bottom ( 2 ) on at least one side of the folded-carton package body that is manufactured in one piece with the folded-carton package body ( 3 ) by folding, whereby a cylindrical blank ( 3 . 1 ) that forms the folded-carton package body ( 3 ) and the at least one bottom ( 2 ) is closed on one end by being pressed flat and welded along a weld seam that runs transversely or perpendicularly to the axis of the blank ( 3 . 1 ), and from the blank ( 301 ), the folded-carton package body and the bottom ( 2 ) that has the weld seam are formed, specifically with the realization of ear-like or triangular two-ply folds or material segments ( 5 ) that are provided on peripheral sides of the bottom ( 2 ), and each form a pocket-like cavity that is closed on the outside, characterized by the fact that the pocket-like cavities are sealed off from the interior of the folded-carton package body ( 3 ) by welding.  
   
   
       11 . Method for the manufacture of a folded-carton package as claimed in  claim 10 , characterized by the fact that the pocket-like cavities are closed off from the interior of the folded-carton package body ( 3 ) by welding the ear-like or triangular material segments ( 5 ) along at least one weld seam ( 6 ).  
   
   
       12 . Method for the manufacture of a folded-carton package as claimed in  claim 11 , characterized by the fact that the respective pocket-like cavity is closed or sealed before the triangular or ear-like material segment is doubled over and fixed on the outer surface of the folded-carton package, for example onto the outer surface of the folded-carton package body and/or of the bottom ( 2 ).
