Packaging pouch

Abstract

A packaging pouch according to the present invention includes a first cover part, a second cover part, and coupling parts. The first cover part includes a packaging area and a sealing area surrounding the packaging area, and a second cover part faces the first cover part to be coupled to the first cover part in the sealing area. Further, the coupling parts are arranged while being spaced apart from each other on the first cover part and the second cover part in the packaging area, and couple the first cover part and the second cover part to each other.

1 . A packaging pouch, comprising:
 a first cover part including a packaging area and a sealing area surrounding the packaging area;   a second cover part facing the first cover part and coupled to the first cover part in the sealing area; and   coupling parts arranged while being spaced apart from each other on the first cover part and the second cover part in the packaging area, and configured to couple the first cover part and the second cover part to each other.   
     
     
         2 . The packaging pouch of  claim 1 , wherein the coupling parts are interposed between the first cover part and the second cover part, and the coupling parts include:
 first coupling members provided on the first cover part while being spaced apart from each other; and   second coupling members provided on the second cover part while being spaced apart from each other, and coupled to the first coupling members so as to one-to-one correspond to the first coupling members.   
     
     
         3 . The packaging pouch of  claim 2 , wherein the first cover part and the second cover part are spaced apart from each other so as to correspond to a space between the adjacent two coupling parts. 
     
     
         4 . The packaging pouch of  claim 2 , wherein the sealing area is defined along a border of the first cover part, and a cutoff portion formed by partially removing at least one side of the first and second cover parts, and a perforated line crossing the packaging area and the sealing area while being in contact with the cutoff portion are formed in the first cover part and the second cover part. 
     
     
         5 . The packaging pouch of  claim 4 , wherein the coupling parts are adjacently positioned to the perforated line. 
     
     
         6 . The packaging pouch of  claim 2 , wherein the first coupling members have a shape protruding from the first cover part, and the second coupling members have coupling recesses accommodating the first coupling members. 
     
     
         7 . The packaging pouch of  claim 1 , wherein each of the first cover part and the second cover part includes a plurality of films stacked each other, and a film stacked at the innermost side among the plurality of films includes Linear Low-Density Polyethylene (LLDPE) or Casting Polypropylene (CPP).
