METHOD FOR OBTAINING DIMENSIONALLY AND STRUCTURALLY STABLE OBJECTS, IN PARTICULAR DISPOSABLE CONTAINERS, STARTING FROM FLEXIBLE FILM, AND OBJECT OBTAINED BY THE METHOD

摘要

A method for obtaining dimensionally and structurally stable objects, in particular disposable containers, from flexible film, characterised by: preparing a flexible film, which, at least in those regions which in the obtained object are required to be substantially rigid, is associated with a structurally transformable substance and at least one passive activator therefor; forming the object from the film prepared in this manner; and during any one stage in the formation of the object, administering energy to said activator to structurally transform said substance and convert said regions from flexible to substantially rigid.
