Stand-up bag

Abstract

In a flat-ended bag made of a flexible film material, two bag wall parts are connected via two longitudinal seams running substantially in a longitudinal direction (z) to form a bag wall that forms a tubular body and has sealing edge strips projecting from the bag wall. The tubular body is closed at both ends, at least one end of the tubular body has a base part disposed substantially perpendicular to the longitudinal axis (z) and serving as a standing surface, and a resealable opening is provided on at least one end of the tubular body. In order to increase the rigidity of the tubular body, the sealing edge strips are folded over onto the bag wall and sealed or glued to the bag wall.

1 . A stand-up bag made of a flexible film material, in which two bag wall parts are connected by two longitudinal seams extending substantially in a longitudinal direction (z) to form a bag wall forming a tubular body, with sealing edge strips projecting from the bag wall, the tubular body being closed at the two ends, at least one end of the tubular body having a base part arranged substantially perpendicular to the longitudinal axis (z) and serving as a standing face and a reclosable opening being provided at at least one end of the tubular body, wherein the sealing edge strips are folded over onto the bag wall to increase the rigidity of the tubular body and are sealed or glued to the bag wall. 
     
     
         2 . A stand-up bag according to  claim 1 , wherein the two sides of the flexible film material are sealable. 
     
     
         3 . A stand-up bag according to  claim 1 , wherein the side of the flexible film material forming the inside of the bag wall is sealable and the sealing edge strips which are folded over onto the bag wall and/or the regions covered by the folded-over sealing edge strips are provided with a sealable coating or with an adhesive coating. 
     
     
         4 . A stand-up bag according to  claim 1 , wherein the standing face is formed by a closure part attached to one end of the tubular body, with a flange having an outlet opening and a closure lid which can reclose the outlet opening. 
     
     
         5 . A stand-up bag according to  claim 4 , wherein the closure lid can be screwed onto the flange or is configured as a folding lid. 
     
     
         6 . A stand- bag according to  claim 4 , wherein the other end of the tubular body is closed by means of a transverse seam. 
     
     
         7 . A stand-up bag according to  claim 4 , wherein a base part is sealed in at the other end of the tubular body to increase the bag volume or an enveloped folding base is provided. 
     
     
         8 . A stand up bag according to  claim 1 , wherein the standing face is formed by a flat base which is produced at one end of the tubular body by folding and sealing the film material or by a sealed-in base part. 
     
     
         9 . A stand-up bag according to  claim 8 , wherein the other end of the tubular body is provided with a closure part with a reclosable outlet opening. 
     
     
         10 . A stand-up bag according to  claim 9 , wherein the closure part is formed by a flange having an outlet opening and a closure lid, which can reclose the outlet opening, or by a zipper closure. 
     
     
         11 . A stand up bag according to  claim 8 , a closure part with a flange having an outlet opening and a closure lid, which can reclose the outlet opening, is arranged in the flat base or in the sealed-in base part. 
     
     
         12 . A stand-up bag according to  claim 11 , wherein the closure lid can be screwed into the flange or is configured as a folding lid. 
     
     
         13 . A method for packaging a pasty, creamy, partly solid/partly liquid, liquid or pourable product, wherein the method comprises packaging the product in a stand-up bag according to  claim 1 . 
     
     
         14 . A method according to  claim 13 , wherein the product is a food. 
     
     
         15 . A stand-up bag according to  claim 5 , wherein the folding lid is articulated to the flange. 
     
     
         16 . A stand-up bag according to  claim 12 , wherein the folding lid is articulated to the flange.
