Abstract
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. An unbonded part is formed on the periphery of the edge of an upper overlapping film of the wrapping film along the marginal line of the same. This unbonded part extends between the marginal line of the upper overlapping film and the edge of the body seal section. A slit is formed in the vicinity of the unbonded part at right angles to the marginal line of the upper overlapping film. A weakly bonded part, where the upper overlapping film and the lower overlapping film are weakly bonded to each other, is formed to be adjacent to the opposite side of the unbonded part of the body seal section relative to the slit, and extends from that side of the unbonded part to a predetermined length along a marginal line of the upper overlapping film.
