Abstract: A method, apparatus and material for continuously forming and filling packages is disclosed. A web of packaging material is coated on one side with a hot melt adhesive while allowing a longitudinal strip adjacent to the edge of the web to remain uncoated. The web thus coated is drawn over a forming shoe which shapes the web into a tube whose interior surface is the coated side of the web, and in which the edges of the web overlap to form a seam such that the uncoated longitudinal strip is the inner overlapped edge. The longitudinal seam is sealed by the coaction of a heated shoe or collar located externally of the tube and a tonque positioned within the tube adjacent the uncoated longitudinal strip. The longitudinal seam is sealed continuously without the accumulation of hot melt adhesive on the tongue. After the longitudinal seam is sealed, the tube is sealed laterally at spaced portions by the coaction of a pair of heated dies.
