Abstract
A tubular film is flattened to form a continuous two-ply film in which the two side edges are continuously connected in the longitudinal direction. This two-ply film is curved into a tubular form, the two side edges are overlapped, and a vertical seal portion is formed in the overlapping portion to form a tube body, and the tube body is filled with a product. The tube body that has been filled with product is horizontally sealed, and the horizontal seal portion that has been thus formed is cut to produce a two-ply bag package.
