PROBLEM TO BE SOLVED: To provide a heat-shrinkable packaging container which is easy to manufacture and has a seal which can be easily peeled off by hand, a break resistance and a strong end seal. To solve this problem, individual end-sealed packaging containers such as bags formed from sheets of heat-shrinkable film having a first edge and a second edge opposite thereto. I will provide a. The packaging container comprises a first bag wall, a second bag wall, opposed first and second lay flat edges, a second lay flat edge, and a distal end having the first edge coupled to the second edge. A first seal defining a tube member having a portion and an opening. Also, the packaging container extends laterally through the first edge and the second edge across the width of both the first and second walls, thereby closing the second end. Including seals. Preferably, at least one of the first and second seals is a peelable seal. This first seal can be a wrap seal, fin seal, butt seal or seal strip. Also disclosed is a method of forming individual end-sealed heat-shrinkable packaging containers. [Selection diagram] Fig. 1 |
