ABSTRACT:
A horizontal form fill packaging and sealing apparatus comprises a film dispenser and a film forming plow which, together with a roller guide, forms the film to be sealed into a tube with the free edges at the side. The object 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 and immediately cooled to approximate impulse sealing, and a cross seal 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 before the back cross seal is made.
