A soap wrapper offers the possibility to wrap both rectangular and oval bars with or without side band, using outlet paper and inner stiffener; this last is useful for a stability to oval and bandless soap bars. This wrapping style is called double-point end fold.
The paper feeding is from heat sealing reel, but some models of soap wrappers are studied to work also with pre-cut sheets. To save money in the last years was invented some kits, assembled on the soap wrappers, to use BOPP (Biaxially oriented polypropylene film) instead of heat sealing paper. BOPP can be transparent or also printed.
