<p>PROBLEM TO BE SOLVED: To solve a conventional problem that in a packaging apparatus for spirally winding a strip film unrolled from a roll around an object to be packaged by revolving the roll of the film around the object, the packaged object causes deformation such as flattening or crushing by the winding of the film in case the object is a white cardboard box or the like. SOLUTION: Oriented films 7 of a first cover layer and a second cover layer are wound around the object 6 to be packaged so that their spiral directions are reverse to each other, whereby the object 6 does not cause deformation such as flattening or crushing. In addition, even when a plurality of objects 6 are to be packaged, each object 6 does not twistedly shift in position, so that a resulted package 5 is neatly packaged.</p> |
