【 International Publication 】 2004-12-29 WO2004/113061 English 【 Abstract 】 Soap bars are packaged in single sheets of material, which can be plastic, paper, cardboard or a combination of these materials in the form of laminates. Soap blocks are packed at a speed of more than 50/min in high-speed machines. A single sheet of material is die cut to form the main portion including the top, bottom and longitudinal side panels and the end flaps attached to each panel. To facilitate folding at the desired point, the sheet of material is weakened by scratches, perforations, or openings at the fold point. This weakening process can be performed just before feeding or during die-cutting. Die cutting can be done while feeding to the packaging machine. The wrapped bar of soap has a flat end surface so that the package can stand on the end and can have corner vents to allow certain moisture and certain aromas to escape at the point of sale.
