Packaging foil, packaging and method of manufacturing said packaging

Abstract

A packaging film having a first edge and a second edge in the longitudinal direction; a first material weakening zone and a second material weakening zone which extend between the first edge and the second edge and between them define an opening strip, wherein the material weakening zones end at a distance from the edges; a first sealing region adjacent to the first edge and a second sealing region adjacent to the second edge, wherein the sealing regions are localised on that side of the packaging film intended as the inner side of the package and the material weakening zones extend into the sealing regions; opening initiating means which are disposed at a distance from at least one of the edges, wherein an edge region between the respective edge and the opening initiating means is free from these opening initiating means.

1 . A packaging film for producing a package, wherein the packaging film comprises a first edge and a second edge in the longitudinal direction, and comprises a first material weakening zone and a second material weakening zone which extend between the first edge and the second edge and between them define an opening strip, wherein the material weakening zones end at a distance from the edges, and
 comprises a first sealing region adjacent to the first edge and a second sealing region adjacent to the second edge, wherein the sealing regions are localised on that side of the packaging film intended as the inner side of the package and the material weakening zones extend into the sealing regions, and   comprises opening initiating means which are disposed at a distance from at least one of the edges, wherein an edge region between the respective edge and the opening initiating means is free from these opening initiating means.   
     
     
         2 . The packaging film according to  claim 1 , wherein a first distance between the first edge at which the material weakening zones end on the one side is greater than a second distance between the second edge at which the material weakening zones end on the other side. 
     
     
         3 . The packaging film according to  claim 1 , wherein the opening initiating means comprise a first slit which is formed at a position corresponding to an intermediate space between the material weakening zones, wherein this first slit is localised adjacent to the second edge having a distance from the second edge corresponding to the second distance or in addition to said first slit comprises a further first slit at said position, wherein the further first slit is localised adjacent to the first edge having a distance from the first edge corresponding to the second distance. 
     
     
         4 . The packaging film according to  claim 3 , wherein the opening initiating means comprise a second slit and a third slit and the first slit is connected to the second slit and the third slit, and the second slit extends from the first slit in the direction of the first material weakening zone and the third slit extends from the first slit in the direction of the second material weakening zone. 
     
     
         5 . The packaging film according to  claim 1 , wherein the opening initiating means are formed adjacent to both edges. 
     
     
         6 . The packaging film according to  claim 1 , wherein the edge region which is free from opening initiating means has a tear-off zone. 
     
     
         7 . The packaging film according to  claim 1 , wherein a separating slit between the material weakening zones runs along the first edge at a distance measured from the first edge which is greater than or equal to the first distance inside the first sealing region. 
     
     
         8 . The packaging film according to  claim 7 , wherein a third material weakening zone and a fourth material weakening zone is formed between the further first slit and the separating slit, wherein the third material weakening zone runs between the first material weakening zone and the end region of the further first slit and the fourth material weakening zone runs between the other end region of the further first slit. 
     
     
         9 . The packaging film according to  claim 7 , wherein the separating slit extends beyond the first and the second material weakening zones. 
     
     
         10 . A method for manufacturing a package using a packaging film according to  claim 1 , comprising the following process steps:
 unrolling and supplying the packaging film in web form and producing a longitudinal fin by looping the packaging film and sealing the packaging film along the edges in the sealing regions, wherein the opening initiating means disposed at a distance from one of the edges despite the existence of the edge region between the respective edge and the opening initiating means, which edge region is free from these opening initiating means, are accessible in the longitudinal fin so that they can be handled freely.   
     
     
         11 . The method according to  claim 10 , wherein when opening initiating means are only formed on one side adjacent to one of the edges when producing the longitudinal fin, that edge on which the opening initiating means are formed and the other edge are aligned such that that edge on which the opening initiating means are formed project so far beyond the other edge in the longitudinal fin that the opening initiating means are localised above the other edge. 
     
     
         12 . The method according to  claim 10 , wherein when opening initiating means are formed on both sides adjacent to both edges when producing the longitudinal fin, the two edges are aligned so that the opening initiating means formed on both sides are localised congruently in the longitudinal fin. 
     
     
         13 . The method according to  claim 10 , comprising a closing of the package by sealing the packaging film at a top or bottom side of the package and separating the packaging film along the separating lines. 
     
     
         14 . A package fabricated according to a method according to  claim 10 . 
     
     
         15 . A package fabricated using a packaging film according to  claim 1 .
