To provide a heat shrinkage and packaging method producing no wrinkles or dimples in a heat shrinkage packaging member for a container having foods or the like mounted on it.

A heat shrinkage film is heat shrunk while liquid material is adhered to an outer surface of a container and the container is packaged with the film. More preferably, an outer surface of the container to which the liquid material is adhered is applied as an extremity end bottom angle portion and/or an extremity bottom ridge part of the container entered at first into a heat shrinking tunnel when the container packaged with the heat shrinking film is fed into the heat shrinking tunnel. Or more preferably, adhesion of liquid material to the outer surface of the container is carried out by spraying liquid material against the container before the container is packaged with a heat shrinking film.
