In terms of up-front capital costs, preformed pouch systems are generally far more expensive, says Mark Dickens, marketing director for processed and prepared foods at Cryovac, Duncan, S.C.
Operating costs, too, may favor f/f/s, Daniels says, since a preformed pouch machine is a little more labor intensive, requiring a worker to load pouches at the front end, while a form/fill/seal system just requires periodic loading of a 2,000- to 3,000-foot film roll.
