To obtain a molding without impairing the shape of a cellulose coating film by separating a film (of especially a bacterial cellulose or a vegetable microfibrous cellulose) from the substrate on which it is formed by dissolving the substrate by treatment with a solvent.
The component used to form a film is one exemplified by a microfibrous cellulose such as a bacterial cellulose obtained by culturing cellulose-producing bacteria, starch, a water-soluble polysaccharide or polyacrylic acid and having adhesion to substrates and film-forming properties. The method for forming a film on a substrate is arbitrary and is exemplified by one consisting of placing a suspension on the surface of a Petri dish and drying the suspension or one consisting of coating or spraying a substrate with a suspension. The substrate used is made of a solvent-soluble plastic or a self-soluble substance. The solvent used is one not adversely affecting the structure of the component used to form a film and is usually toluene, methanol or the like.
