Abstract
A method of encapsulation is characterised by supplying to an encapsulation unit two films of like material capable of deforming elastically at least when partially solvated, and applying solvent to at least one of the films prior to encapsulation to cause partial solvation of the material surface, such that the partially solvated surface can adhere to and seal with the film material. In the encapsulation unit the substance to be encapsulated e.g. a cosmetic oil or vitamin preparation is supplied between the films, the films are formed, typically by a moulding process, into suitably shaped capsule portions which can adhere to each other as a result of the adhesive action of the partially solvated surface(s), and which seal together encapsulating the supplied substance, forming a capsule. The invention enables encapsulation using materials other than gelatin, such as polyvinyl alcohol. Also disclosed is encapsulation apparatus and the resulting capsules.
