Abstract
A heat-shrinkable holder for securing articles, a package securing such articles using heat-shrinkable sheets, a shrinkable sleeve, and a method and device for securing such articles using heat-shrinkable sheets and sleeves are disclosed. The holder is constructed so that it is separable when desired, and may comprise the labeling or the like for an article to be packaged. Releasable fasteners such as adhesives, heat seals, and/or perforations may be employed on the sheets. If desired, articles may be individually sleeved with a heat shrinkable film blank portion, which may function as labeling.

22. A method of packaging articles comprising:
-
creating a first and second blank strip by joining a first sheet of heat-shrinkable material and a second sheet of heat-shrinkable material at discrete joinder portions spaced along the first and second sheet so as to form a plurality of openings, each opening located between each adjacent pair of joinder portions; perforating the first and second sheets at the discrete joinder portions; joining the first and second blank strips by applying a releasable fastener to the first and second blank stops spaced from the perforations; inserting an article into each of the openings; separating the sheets are articles at predetermined locations into groups of articles; and heating the first and second sheets to shrink the first and second sheets thereby forming a unitary package of the sheets and the groups of inserted articles. - View Dependent Claims (23, 24, 25, 26, 27)
