Abstract

There is provided an apparatus and method of packaging commodities in a flexible wrapper. The apparatus includes first and second stations with a wrapper engaging assembly moving between the first and second stations, wrapper cutting and sealing means which severs a bag length from a continuous roll of flexible material, a component for opening the open leading end of the wrapper at the second station, a funnel which is preferably expandable and which engages the open mouth of the wrapper so as to permit loading of the commodity into the wrapper, and a further assembly which seals the open mouth of the bag length, preferably under vacuum, by having a component preferably in the form of a pair of fingers which engages the mouth of the bag to place it under tension whereafter a sealing assembly seals the mouth of the bag to form an improved weld across the mouth of the bag.
