Abstract (en)
A method of continuously forming, filling and sealing of packages with a continuous web (14) of polyethylene film material includes the steps of folding the web (14) to provide confronting sides (20) joined along a bottom edge (22) and sealing by training the web (14) onto a vertical seal former (34) having plurality of vertical sealers (40) and progressively forming each vertical seal (46) as the web (14) is being continuously moved with the vertical sealer (40) while at the same applying a low temperature sealing action to allow the area of the film being sealed to be progressively melted. This process forms a series of horizontally disposed pouches (48) severed by the vertical seals (46) extending transversely of the web (14) leaving sealed side edges (50) of each pouch (48) partially severed from one another with upper portions (52) of each pouch (48) also remaining connected with adjoining pouches (48) and having opposed sidewalls (54) of each pouch (48) unsealed along a top edge (56) preparatory to filling. A packaging apparatus 10 is also provided for continuously forming filled and sealed packages (12), each having an expanded bottom end (142) capable of receiving a greater amount of fill. <IMAGE>
