ABSTRACT:
A package is provided which is formed of a plastic film such as polyethylene or polypropylene. The package is formed to define an internal chamber to accommodate an article to be packed. A slit is provided in the wall and a hanger is provided a part of which extends through the slit. This part is provided with projections which lock the hanger against retraction into the internal chamber. The projections are rounded and/or wedge shaped to facilitate penetration of the hanger through the slit. According to the method by which such a package is formed the projections are shaped to penetrate through the slightly smaller slit without exceeding the elastic limit of the material from which the package is formed. Thereby the material can resume its original shape after the projections have been forced through the slit.
