A thin film made of an amorphous material having supercooled liquid phase region is formed on a substrate. Then, the thin film is heated to a temperature within the supercooled liquid phase region and is deformed by its weight, mechanical external force, electrostatic external force or the like, thereby to form a thin film-structure. Thereafter, the thin film-structure is cooled down to room temperature, which results in the prevention of the thin film's deformation.

The present invention concerns a high melt strength propylene polymer or copolymer suitable for manufacturing foams and thermoformed product exhibiting a melt strength of at least 3 g and comprising a high molar mass portion and a low or medium molar mass portion.
