ABSTRACT:
A film of heat shrinkable plastic material is wrapped about four sides of an object and heat welded. A second heat shrinkable film is wrapped and heat welded about the object at right angles to the wrap of the first film. Both films are wider than the package faces about which they are wrapped. The films are heated to shrink both films and to cause the overlapping portions of the two films to heat bond together.
