A method of manufacturing a package for flowable media and the use of a synthetic plastics sheet for the manufacturing process A method of manufacturing a package (1) which is filled with a flowable medium and which comprises a tube (3), a bottom and a top wall (2) of shapeable synthetic plastics material in which the package (1) formed by shaping and the action of heat is filled, sealed and carried away is described. In order to provide an environmentally friendly manufacturing method in which a package can be produced by deepdrawing and without any substantial amount of waste material, it is according to the invention envisaged that two prepared blanks (4), each of which takes the form of a flat sheet, should be heated at a distance from each other (in III-V) and then brought together along a frame-like strip (7 to 11) and, accompanied by (at V) deep-drawing of the middle zone (12) within the frame-like strip (10), welded together to form the package space, an aperture (13) being provided in a top wall (2), the package (1) which is thus formed and which is fluid-tight with the exception of the aperture zone (3) being then cooled, conveyed onwardly (18 to 20), filled (in position XI) and sealed by an opening member (14) which masks the aperture (13).
