         9 . The package according to  claim 8 , wherein the crease line arrangement extends from a lower region of the hollow body to the upper end, wherein said lower region is arranged between the bottom end and said upper end. 
     
     
         10 . The package according to  claim 1 , wherein the hollow body is made of a packaging laminate. 
     
     
         11 . A blank made of a packaging material comprising pre-formed crease lines, wherein the blank is configured such that it forms a package according to  claim 1  when its lateral sides are sealed together to form a hollow body and a bottom section of said hollow body is sealed to form a closed bottom end, when it is folded along the pre-formed crease-lines, and when it is connected to a top portion of a polymeric material, said top portion having a periphery defining a planar shape having a waist. 
     
     
         12 . The blank according to  claim 11 , having a first end, a second end and two lateral ends extending between the first end and the second end, said blank comprising
 a first set of crease lines arranged at said first end, wherein   said blank is sealable along the two lateral ends for forming a hollow body,   said first set of crease lines is disposed such that said first end is forming a closed bottom end when said blank is folded along said first set of crease lines, and wherein the first set of crease lines comprises   a first configuration of crease lines disposed such that a front side of the bottom end is formed when the blank is folded along the first disposition of crease lines, wherein said front side has at least three corners, and   a second configuration of crease lines disposed such that a back side of the bottom end is formed when the blank is folded along the second disposition of crease lines, wherein said back side has two corners.   
     
     
         13 . The blank according to  claim 12 , wherein the first configuration of crease lines is disposed such that a front side of the bottom end is formed when the blank is folded along the first disposition of crease lines wherein said front side has at least three corners. 
     
     
         14 . The blank according to  claim 12 , further comprising a second set of crease lines arranged at said second end, wherein
 said second set of crease lines is disposed such that said second end is assisted in conforming to a top portion having a waist.   
     
     
         15 . The blank according to  claim 14 , wherein said second set of crease lines comprise crease lines extending from the second end towards a lower region, said lower region being arranged between the first end and said second end, said crease lines being disposed such at the second end that they may substantially align with the waist of a top portion. 
     
     
         16 . The blank according to  claim 14 , wherein said second set of crease lines
 extends from the second end towards a lower region, said lower region being arranged between the first end and said second end, and wherein said second set of crease lines,   comprises a first pair of mutual reversed crease lines, wherein one crease line is positioned on each side of a plane of symmetry of the package to be formed, said plane being substantially perpendicular to a plane corresponding to the package bottom, said first mutual reversed crease lines being positioned at a distance from said plane and angled in respect of said plane,   comprises a second pair of mutual reversed crease lines, wherein one crease line is positioned on each side of said plane of symmetry, said second mutual reversed crease lines being positioned at a distance from said plane and angled in respect of said plane, and   comprises a third pair of mutual reversed crease lines, wherein one crease line is positioned on each side of said plane of symmetry, said third mutual reversed crease lines being positioned at a distance from said plane and angled in respect of said plane.   
     
     
         17 . The blank according to  claim 16 , wherein
 the first pair of mutual reversed crease lines is arranged closest to the plane and is having a first angle to the plane,   the second pair of mutual reversed crease lines is having a second angle to the plane, said second angle being larger than the first angle,   the third pair of mutual reversed crease lines is having a third angle to the plane, said third angle being larger than the second angle,   the crease lines of the first and third pairs, on each respective side of the plane, are connected by a curve, and   the crease lines of the first, second and third pairs are angled such in relation to the plane that the angles increase in a direction towards the second end.   
     
     
         18 . The blank according to  claim 14 , wherein the first set of crease lines and the second set of crease lines are arranged such that a longitudinal sealing formed when the two lateral ends are connected to each other does not pass through the first or second set of crease lines. 
     
     
         19 . A reel of packaging material comprising a continuous web having pre-formed crease lines, wherein the reel is configured such that a plurality of blanks according to  claim 11  are formed when the continuous web is cut. 
     
     
         20 . A method for forming a package according to  claim 1 , comprising the steps of:
 providing the hollow body by sealing two lateral ends of a blank   closing one end of said hollow body by injection molding the top portion onto the upper end of said hollow body,   filling said hollow body with a food product, and   closing the package by sealing the bottom end of said package.
