Scale Machines

A form-fill-seal machine (form, fill, and seal), which uses a scale to weigh the amount of product to be inserted into the pouch. (See Scale Equipment). Form-fill-seal (form, fill, and seal) machines form a pouch from a flat web of film of heat sealable film and insert product into the pouch before sealing the pouch. Horizontal form-fill-seal machines fold incoming film in half length-wise. Form-fill scale machines then seal and cut the sides of the pouch to a specific length. The two side seals and the bottom fold forms an open top pouch. The pouch is then filled and the top opening sealed. Vertical form-fill-seal machines wrap incoming film around a tube. The two edges of the film are sealed together to form a tube of film. The bottom of the tube is sealed, the product is filled into the pouch, and the top of the tube of film is seal and cut from the rest of the tube of film.
