ABSTRACT:
A method of utilizing a shrink wrap film to shrink wrap or bundle a load of articles or packages having a surface portion formed of the same material as the shrink wrap film. The load is assembled and wrapped with a laminate comprising an outer ply formed of the shrink wrap film and an inner barrier film formed of a material which will not fuse to any part of the load or said portions when subjected to film-shrinking heat. The wrapped load is thereafter heated to shrink the laminate about the load. Also disclosed is the resultant package, as well as several different laminates which may be used.
