PACKAGE AND METHOD OF FORMING

摘要

An article package comprises a pair of complementary cavity defining half sections constituting opposite portions of an article enveloping structure, and a pair of seams forming oppositely disposed junctions between a pair of opposite edges of one half section and the corresponding edges of the other half section. The package half sections are formed of heat shrinkable sheet material which is stretched initially to form the cavities and the heating pattern and stretching operation are such that the corners of the resulting cavity defining half sections are not stretched to an unduly thin condition. After the package is formed heat is applied in a predetermined manner so as to shrink the half sections into conformity with the packaged items and so as to control the thickness of certain areas of both half sections.
