ABSTRACT:
This invention relates to a process for packaging an article with a thermoplastic resin film in which the film is rolled on the two rolls on both side so that an intermediate region thereof may be extended in tension condition between the rolls, and an article to be packaged is fed through a space between the rolls so as to push against the extended intermediate region of the film and be wrapped therewith, and overlapped portions of the wrapping film are set in parallel with the surface of the article and are fused together, and at the same time are cut so that there may be obtained such a fused adhesion line on the overlapped portions of the film that extends in the lateral width of the film and is longer in length than the width of the film, so that there is obtained the packaged article in which the fused overlapped portions of the packaging film is laid along on the surface of the article and, on the other hand, there is obtained an intermediate region of the film which is extended between the two rolls and has the foregoing fused overlapped portions.
