Abstract
Soap bars can be effectively packaged in substantially transparent materials so that the soap bar can be seen through the packaging material. This is particularly useful with decorative colored translucent soap bars. The soap bars first are at least partially enveloped in a first relatively thick and stiff substantially transparent film and then fully enveloped in a second relatively thin substantially transparent film. The soap bars are generally rectangular but with rounded edges and a shape that tapers in cross-section from a midpoint of the soap bar to the ends. The first film forms a substantially rectangular cylinder which envelops about 95% to about 105% of the soap bar. This rectangular cylinder is open at each end. The second film fully envelops the soap bar. The end package provides a soap bar maintained within a rectangular cylinder with a low fragrance loss and a moisture transmissivity of less than about 3 gm/m2/day.
