Abstract
A form, fill and seal pouch packaging machine is augmented by including a heating component for heating the surfaces of its film during product addition. The film is heated to a temperature sufficient to inhibit condensation of hot liquid product on the interior walls of a partly formed pouch during the product addition and/or to achieve asepsis during product addition. The heating member can be positioned in one of several positions adjacent to the surfaces of the film. Irrespective of the positioning of the heating member the surfaces of the film of a partially formed pouch or of the film prior to formation of the pouch is heated to a temperature sufficient to inhibit condensation of vapor on the film and/or to sterilize the surfaces of the pouch.
