Abstract
The disclosure describes a thermoforming machine, which can include a horizontal intermittent motion thermoforming machine, and a mold, wherein the mold contains a plurality of pocket forming cavities in a 2-dimensional array. These cavities can each be defined by side walls and a base, and each cavity can be surrounded by a planar surface of the mold on all sides. Further, the cavities can be positioned in the array so as to provide a plurality of continuous strips of uninterrupted planar surface of the mold from a leading to a trailing edge of the mold. These cavities can have rounded bottom corners, formed where the side walls meet the base, and rounded edges, formed where side walls meet an upper surface of the mold. The thermoforming machine can be further configured to be able to draw a web of water-soluble film down into the cavities.
