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. This plastic film 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 preferably about 7 to 20 can be used. The soap bar in order to facilitate making an effective longitudinal seal on the bottom of the soap bar package should have a planar surface adjacent to the position of the overlapping longitudinal edges of the wrapping film. This provides a surface for the sealing plate to seal the longitudinal edges against.
