<p><P>PROBLEM TO BE SOLVED: To provide a heat-shrinkable packaging receptacle which is easy to manufacture and is provided with a seal which is easy to peel with a hand, and with a high-strength end seal resistant to breakdown. <P>SOLUTION: The individual end-sealed packaging receptacle is formed, like a bag, from a heat-shrinkable film sheet, having a first edge and an opposing second edge. This packaging receptacle includes a first seal bonding the first edge and the second edge to define a tube member having a first bag wall, second bag wall, first and second opposing lay-flat bag edges, an end and an open mouth. The packaging receptacle includes a second seal through the first and second bag edges, extending laterally across the width of both the first and second bag walls and thereby closing the end. Preferably, at least one of the first and second seals is a peelable seal. The first seal may be a lap seal, a fin seal, a butt-seal, or a seal strip. A method of forming an individual, end-sealed, heat-shrinkable packaging receptacle is also disclosed. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
