ABSTRACT:
Food packaging articles are manufactured by providing top and bottom sheets of flexible material and securing selected areas of the sheets along sealing edges to define a plurality of triangular-shaped pouches, with each pouch corresponding to an individual food packaging article. The sealing edges preferably are secured by fusion or adhesion welding. In an illustrative embodiment, the sealing edges are secured by ultrasonic welding using a pair of weld heads that are positioned to weld lines at different angles from one another.
