Polymeric Packages

Abstract

This disclosure relates to a package and a method of making the package. The package comprises (a) a web material to form an enclosed package comprising a seal having two seal ends and a package side edge, and wherein the seal is a fin seal or an overlap seal; (b) a first tear initiation point located on the package side edge; and (c) a second tear initiation point, wherein the second tear initiation point is located on the seal.

1 . A package comprising:
 a. a web material with a first edge portion and a second edge portion, said first edge portion and said second edge portion being sealed together to form a seal having two seal ends, said package having a first package end at one seal end and a second package end at the other seal end;
 wherein said first package end and said second package end define a first package side edge and a second package side edge, wherein said first package side edge and said second package side edge comprise folded web material, and wherein said seal is a fin seal or an overlap seal; 
   b. a first tear initiation point located on said first package side edge; and   c. a second tear initiation point,
 wherein said second tear initiation point is located on said fin seal, said fin seal being folded toward said first package side edge; or wherein said second tear initiation point is located on one of said edge portions of said overlap seal, said one of said edge portions of said overlap seal being folded toward said first packing side edge. 
   
     
     
         2 . The package of  claim 1 , wherein said first tear initiation point and said second tear initiation point are aligned across said package. 
     
     
         3 . The package of  claim 1 , wherein at least one of said pocket ends is sealed. 
     
     
         4 . The package of  claim 1 , wherein said web material comprises oriented polypropylene film. 
     
     
         5 . The package of  claim 1 , wherein said web material comprises metallized oriented polypropylene film. 
     
     
         6 . The package of  claim 1 , wherein said first tear initiation point and/or said second initiation point is a structure weakness induced by laser scoring and/or mechanical cut. 
     
     
         7 . The package of  claim 1 , wherein said web material is free of aluminum foil. 
     
     
         8 . The package of  claim 1 , wherein said first tear initiation point and said second tear initiation point are aligned substantially perpendicular to said first package side edge. 
     
     
         9 . The package of  claim 1  is a vertical-form-fill-and-seal package or a horizontal-form-fill-and-seal package. 
     
     
         10 . A method of manufacturing a package comprising:
 a. forming a package comprising a web material with a first edge portion and a second edge portion, said first edge portion and said second edge portion being sealed together to form a seal having two seal ends, said package having a first package end at one seal end and a second package end at the other seal end;   wherein said first package end and said second package end define a first package side edge and a second package side edge, wherein said first package side edge and said second package side edge comprise folded web material, and wherein said seal is a fin seal or an overlap seal;   b. generating a first tear initiation point located on said first package side edge; and   c. generating a second tear initiation point,
 wherein said second tear initiation point is located on said fin seal, said fin seal being folded toward said first package side edge; or wherein said second tear initiation point is located on one of said edge portions of said overlap seal, said one of said edge portions of said overlap seal being folded toward said first packing side edge. 
   
     
     
         11 . The method of  claim 10 , wherein said step (a) comprises vertical-form-fill-and-seal package or horizontal-form-fill-and-seal package. 
     
     
         12 . The method of  claim 10 , wherein said first tear initiation point is generated by laser scoring said web material prior to form said package. 
     
     
         13 . The method of  claim 10 , wherein said first tear initiation point is generated by mechanical cut inside the seal area of one of the seal ends. 
     
     
         14 . The method of  claim 10 , wherein said second tear initiation point is generated by mechanical cut of said fin seal or said one of said edge portions of said overlap seal. 
     
     
         15 . The method of  claim 10 , wherein said second tear initiation point is generated by laser scoring said edge portions such that the laser scored portions of both edge portions are substantially overlapped with each other in said fin seal, or laser scoring said one of said edge portions of said overlap seal. 
     
     
         16 . The method of  claim 10 , wherein said web material comprises oriented polypropylene film. 
     
     
         17 . The method of  claim 10 , wherein said web material comprises metallized oriented polypropylene film. 
     
     
         18 . The method of  claim 10 , wherein said web material is free of aluminum foil. 
     
     
         19 . The method of  claim 10 , wherein said first tear initiation point and said second tear initiation point are aligned substantially perpendicular to said first package side edge.
