This invention relates to a method of utilizing a shrink wrap film to shrink wrap a load or group of articles or packages having a surface portion formed of the same material as the shrink wrap film. The load or group is assembled and wrapped with the outer ply of each article or package formed of the shrink wrap film being coated with a release coating which will withstand the heat shrinking and will not fuse to any part of the load or group when subjected to film-shrinking heat when the group is overwrapped with similar film. The wrapped load is thereby heated to shrink the film or laminate about the load, and may thereafter be easily removed.

The method of making a double-wrapped pack comprising the steps of shrink-wrapping a plurality of similarly-shaped articles in a first heat-shrinkable ethylene polymer film to form a first package, assemblying a plurality of said packages to form an aligned group, and shrink-wrapping said aligned group within a second heat-shrinkable ethylene polymer film to form a second package, the contacting interface of one of said films being coated with a thin, substantially-continuous release coating of solvent-based polyamide to facilitate ready separation of said films upon opening of said second package.
