ABSTRACT:
A method for sealing an object having a peripheral surface, surfaces substantially perpendicular to the peripheral surface and infinite enlongated bodies projecting from the surfaces perpendicular to the peripheral surface, which method comprises: wrapping the peripheral surface with a heat-shrinkable film in such a manner that both side edges of the film extend beyond the side edges of the peripheral surface; bonding longitudinal edges of the film to each other; and heating the heat-shrinkable film to permit the film to shrink to thereby seal the peripheral surface and a peripheral portion of the surfaces perpendicular to said peripheral surface, except said infinite elongated bodies.
