Abstract: A method for obtaining dimensionally structurally stable objects, in particular disposable containers, from a flexible film rewindable on a reel, comprising the steps of preparing a flexible film rewindable on a reel, which, at least in those regions which in the obtained object are required to be substantially rigid, is associated with a structurally transformable substance inert with respect to the film and at least one passive activator therefore, forming an object from the film prepared in this manner, and during any one stage in a formation of the object, administering an energy compatible with the activator to start a structural transformation reaction of the substance and convert the regions from flexible to substantially rigid.
