Soap bar wrapper
Soap bars ( 10 ) 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 ( 40 ). This plastic film ( 40 ) 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 ( 10 ) 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 ( 40 ). This provides a surface for the sealing plate to seal the longitudinal edges against.
1. A wrapped soap bar comprising a generally rectangular soap bar wrapped laterally with a film having a thickness of about 60 micron to about 180 micron and a Taber Stiffness of more than about 5, the longitudinal ends of said soap bar enclosed by a folded over edge portion of said film, said soap bar having a longitudinal planar area on a lower surface adjacent to an overlap of end edges of said film that are sealed to form said, wrapped soap bar, the wrapped soap bar being devoid of a stiffener reinforcing element.
2. A wrapped soap bar as in claim 1 which said thickness is about 90 micron to a about 150 micron and a Taber Stiffness of about 7 to 20.
3. A wrapped soap bar as in claim 1 wherein said film is a biaxially oriented thermoplastic film.
4. A wrapped soap bar as in claim 1 wherein said film is selected from the group consisting of polyethylenes, polypropylenes, vinyl polymers, acrylic polymers and copolymers, styrene polymers and copolymers and polyesters.
5. A wrapped soap bar as in claim 4 wherein the film is polyethylene.
6. A wrapper soap bar as in claim 4 wherein said thermoplastic film is polypropylene.
7. A wrapper soap bar as in claim 4 wherein said thermoplastic film is biaxially oriented polypropylene.
8. A wrapped soap bar as in claim 1 wherein said thermoplastic film is polyvinyl chloride.
9. A wrapped soap bar as in claim 1 wherein said thermoplastic film is polyethylene terephthalate.
10. A wrapped soap bar as in claim 1 wherein said folded over end portions of said film are sealed.
