This invention relates to a water-soluble film (WSF) system with embedded/entrapped water-soluble films (WSF). More particularly, the invention relates to a WSF system with actives embedded/entrapped therein such as to provide precise and desired release of actives there from and its method of manufacturing for diverse applications, in which a variety of substances such as detergents, enzymes, softeners, perfumes, pesticides, fungicides, active ingredients, dyes, pigments, hazardous chemicals, active agents for cleaning laundry, dishes, floorings, walls, furniture, fluffs, pulp, etc., and the like can be so embedded/entrapped for such purpose. The invention further discloses novel online and offline process for the manufacture of such multi-layered WSF with or without liners and of desired shapes to selectively entrap interacting/non-interacting materials and their combinations. The process also provides options for the use of a wide range of raw materials, liners such as paper, film, foil, fabric, etc.
