Packaging pouch

Abstract

A packaging pouch ( 10 ) made from a flexible film material and having at least one sealing zone arranged along a pouch edge and an outer sealing seam ( 18 ) as permanent closure element is such that, in order to increase the shock-absorbing capacity of the sealing zone, a region ( 22 ) of the sealing zone bordering the interior ( 20 ) of the pouch exhibits lower bond strength than that of the outer sealing seam ( 18 ).

1 . A packaging pouch made from a flexible film material that has at least on sealing zone arranged along a pouch edge and an outer sealing seam ( 18 ) as a permanent sealing element, in order to increase the capacity of the at least one sealing zone to absorb shock, a region of the at least one sealing zone bordering inner part ( 20 ) of the packaging pouch has lower bond strength than that of the sealing seam ( 18 ).  
     
     
         2 . The packaging pouch according to  claim 1 , wherein the region of the at least one sealing zone bordering interior of the packaging pouch is a sealing seam ( 22 ) having lower bond strength than that of the outer seam ( 18 ).  
     
     
         3 . The packaging pouch according to  claim 1 , wherein the region of the at least one sealing zone bordering the inner part of the packaging pouch exhibits a plurality of sealing areas ( 24 ,  26 ,  30 ) spaced apart from each other and has same or lower bond strength than that of the outer seam ( 18 ).  
     
     
         4 . The packaging pouch according to  claim 3 , wherein the sealing areas that are spaced apart from each other, and exhibit geometric elements ( 24 ) surrounded on all sides by seal-free regions.  
     
     
         5 . The packaging pouch according to  claim 3 , wherein the sealing areas that are spaced apart from each other form a geometric pattern.  
     
     
         6 . The packaging pouch according to  claim 3 , wherein the sealing areas that are spaced apart from each other are strips ( 26 ) that project out from an inner edge ( 19 ) of the outer seam ( 18 ) towards the interior of the packaging pouch.  
     
     
         7 . The packaging pouch according to  claim 3 , wherein the sealing areas that are spaced apart from each other are strips ( 30 ) that project out from an inner edge ( 19 ) of the outer seam ( 18 ) and are delimited by inward projecting seal-free regions ( 28 ).  
     
     
         8 . The packaging pouch according to one of the  claim 7 , wherein the region of the at least one sealing zone, bordering the interior of the packaging pouch and having lower bond strength than that of the outer stream ( 18 ), runs the whole length of the outer sealing seam ( 18 ).  
     
     
         9 . The packaging pouch according to  claim 7 , wherein the region of the at least one sealing zone, bordering the interior of the packaging pouch having lower bond strength than that of the outer stream ( 18 ), runs over at least part of the length of the outer sealing seam ( 18 ).  
     
     
         10 . The packaging pouch according to  claim 1 , wherein the region of the at least one sealing zone, bordering the interior of the packaging pouch having lower bond strength than that of the outer stream ( 18 ), runs the whole length of the outer sealing seam ( 18 ).  
     
     
         11 . The packaging pouch according to  claim 1 , wherein the region of the at least one sealing zone, bordering the interior of the packaging pouch having lower bond strength than that of the outer stream ( 18 ), runs over at least part of the length of the outer sealing seam ( 18 ).
