Bag Including Easy Open Feature and Method of Construction

Abstract

A bag for containing food products or the like comprises a tubular body section with flanged end seals, having the structural seam creating the tubular body section of the bag positioned along the edge of the bag and incorporated as a tear propagation feature to promote ease of opening and enhanced product access.

I claim: 
     
         1 - 12 . (canceled) 
     
     
         13 ) A bag made of tear compliant material and featuring a tear-open strip, said bag constructed using a vertical bag forming machine, said construction comprising the steps of:
 wrapping bag construction material around the funnel shaped product delivery tube of said vertical bag forming machine, said material overlapped and sealed, forming the vertical main body seam and therein creating the tubular body section of said bag,   fabricating a first transverse seal across said tubular body section therein creating a bottom seal, with the terminal end of said first transverse seal being positioned in close proximity to said vertical main body seam,   insertion of product to be contained into said bag through said product delivery tube,   moving said tubular body section downward and off of said product delivery tube,   fabricating a second transverse seal across said tubular body section therein creating a top seal, with the terminal end of said second transverse seal being positioned in close proximity to said vertical main body seam,   incorporating a tear initiation feature in the form of a cut or notch into at least one said transverse seal in close proximity to said vertical main body seam,   severing and removing said filled and sealed bag from said vertical bag forming machine.   
     
     
         14 ) The bag of  claim 13  wherein said vertical body seam comprises an outward projecting flange seal. 
     
     
         15 ) The bag of  claim 13  wherein said vertical body seam comprises a butt seam having no overlap of material or projecting flange seal.
