This invention relates to a method of automatically forming packages of materials or goods such as milk packages from flexible film and to the novel packages produced thereby. The roll stock film is passed over a forming shoulder to give it a tubular shape and the opposite edges are joined by a sealing bar to form a tubular portion. The milk pouches or other material to be packaged are then dropped into the tubular portion which has previously been laterally sealed across the bottom. The weight of the pouches draws the film down between a pair of reciprocating cutting and sealing jaws when they are opened until the pouches come to rest upon a pivotal support member. The jaws are then closed to form two lateral seals, i.e. one for that package and one for the next package, and a lateral cut separates the packages. The package thus formed may also have an upper handle portion.
A method for automatically repeatedly packaging material in a flexible film package made from a continuous stock of film, said package having a substantially vertical heat seal joining the edges of the film into a tubular portion, a lower lateral heat seal, an upper lateral heat seal and the material being disposed in the so sealed package, comprising:
