ABSTRACT:
A method for forming an inflated gift wrapping includes the insertion of a gift or other item into an open-end of an envelope, at least partially inflating the envelope with an inert gas and thereafter completely sealing the envelope. The envelope is thus formed into an inflated gift wrapping, preferably composed of a pair of overlying panels that are heat-sealed together about their perimeters. In a preferred embodiment of this invention, the packaged item is inserted into a first open-end of the envelope, the first end of the envelope is heat-sealed, the envelope is pressurized with the inert gas through a second and opposite open end thereof, and then the second end of the envelope is heat-sealed to form a fully closed and sealed wrapping.
