The outer surface of an article is covered with a wrapping film, and both ends of the wrapping film are lap-welded by heating, so that a body seal section is created. A removal tab is created at a position close to the longitudinal end thereof by slits that are spaced apart from each other by a predetermined distance and cut parallel to each other along the marginal line of the body seal section on an upper overlapping film of the wrapping film. A perforated section is created and extended in line with one of the slits that constitute the removal tab in such a way that it crosses an imaginary continuation from this slit and departs from another imaginary continuation from the remaining slit. The end of the removal tab is picked up with fingers, and the fingers are moved in a direction of an arrow A, and the wrapping film is torn up from the slits. A split from one of the slits reaches the perforated section. Further pulling of the removal tab in the A direction causes the split from the slit to spread along the perforated section, and a split from another slit also spreads, whereby the wrapping film is widely opened.
