1. A process for sequentially forming a plurality of enclosed tetrahedral containers comprising a product, the process involving: passing a continuous web, comprising a strip of container material having two opposing edges, to a folding station, whereupon each open container is sequentially formed by folding the web, to bring into contact two contiguous edge portions from only one edge of the web, then sealing the two edge portions together to form a portion of the web into an open container, wherein the open containers are tetrahedral containers, albeit with one face missing; wherein the edge which is folded alternates from one container to the next; depositing the product onto the web so that it is held within the open containers, and then sealing the open containers to form the enclosed tetrahedral containers comprising the product.
