Abstract
A method of producing a package for fluids made of a synthetic plastic material, in which a strip of the material is shaped to form two rows of tub-shaped containers which are filled, sealed, pairs of them being folded together to form a single container, and welded closed into a single container. In a particular preferred embodiment, two plastic webs are first brought together continuously and sealed along outer edges, to form a tube, with the tube then being filled from above, with thereafter transverse seals provided between pairs of adjoining tub-shaped containers.
