Abstract
In the process and plant for forming double-pouch containers, two continuous external ribbons (), facing one another, are fed in an advancement direction to an infeeding zone where a third, central ribbon () is inserted between the external ribbons (). The pouches are formed by injecting a forming fluid between the external ribbons () in order to determine an expansion thereof against compartments of two half-molds having a shape which corresponds to a final pouch shape. Each container has two similar pouches, one facing another, which are defined by a pair of external walls and by a central wall coupled along a perimeter thereof to the external walls. The process enables rapid and economical formation of double-pouch containers.
