ABSTRACT:
A packaging machine of the type, in which products are inserted into the gap between two halves of center-folded film. The machine comprises two sealers. The first sealer cuts and heat-seals the center-folded film along a line extending at right angles to the fold of the film, thereby forming a bag containing a product. The second sealer heat-seals each bag at the open side thereof which extends parallel to the fold of the film. The machine further comprises a clamper and an evacuator. The clamper clamps the open side of the bag before the bag is sealed completely. The removes air from the bag through the clamper before the bag is sealed completely.
