Abstract:
A process for producing inclusion packaged products, said product comprising:(i) an inclusion cell formed from a base sheet and an overlapping sheet, wherein the base sheet and the overlapping sheet each has a thickness of about 1-100 microns, and the thickness of the overlapping sheet is not greater than that of the base sheet; and (ii) a thin-leaf inclusion article, comprising a water soluble polymer in the form of a thin film having a thickness of about 10-500 microns, which inclusion article is obtained by providing about 10-50 w/w % solution of the thin-leaf inclusion article and one or more ingredients selected from the group consisting of ingredients, cosmetic ingredients, and pharmaceutical ingredients, depositing the solution onto a prescribed portion of the base sheet, and then evaporating the solvent from the solution by a dryer at a temperature of 40-100Â° C. to dry and form the thin-leaf inclusion article, said process comprising: (1) placing the overlapping sheet over the thin-leaf inclusion article; and (2) sealing appropriate selections of the overlapping sheet onto the base sheet to create the inclusion cell to enclose the thin-leaf inclusion article which is adhered to the base sheet and which is smaller than the inclusion cell, whereby the thin-leaf inclusion article can be freely detached from the base sheet.
