<p>Soap bars that are not of essentially a square or rectangular shape, but of a generally rectangular shape, can be packaged using a single plastic film wrapper (42). This plastic film (42) preferably is biaxially oriented polypropylene of from about 60 micron to about 180 microns. It can be a monolayer or a multilayer laminated. However, any plastic film having a Taber stiffness of more than about 5 and preferable about 7 to 20 can be used. In order to assist in making folds to form the end walls, the film material can be weakened by being thinned, perforated or slit at the fold points or lines. In addition, in order to make the longitudinal sealin the package bottom surface the seal plate can be of a shape that is complimentary to the shape of the bottom surface of the soap bar.</p> |
