2126747 9410039 PCTABS00032 A form fill packaging and sealing apparatus (10) comprises a film dispenser (12) and a film forming plow (22) which, together with a roller guide (20), forms the film (16) to be sealed into a tube (14) with the free edges at the side. The object (19) to be packaged is inserted into the film tube. The free edges of the film are longitudinally sealed together at the side of the package by a rotary heat sealer (30) and immediately cooled to approximate impulse sealing. The quality and width of the longitudinal seal (6) can be adjusted by changing the amount that the film is preheated before sealing. A cross seal (5) is made at the front and back of the object to be packaged. The excess gas in the package is pressed out by a presser (78) before the back cross seal is made.
