The present invention discloses a novel ion-pair delivery system based mask compositions for face, hair, skin, and body applications. These compositions come off from the site of their application essentially in one piece with the appearance, for example, of a piece of sea-weed or a continuous film. These mask compositions are suitable for a variety of delivery system methods, such as peel-off mask, moisturizing mask, exfoliating mask, prosthetic mask, soaking mask, depilatory mask, rub-off mask, two-phase mask, two-compartment mask, heat-releasing mask, and such. These mask compositions are made from the biopolymer based films that are cross-linked with divalent or trivalent metal cations. During the cross-linking process, such divalent and trivalent metal cations may also act as release agents for other face, hair, skin, and body beneficial compositions in their enhanced bioavailable forms by an ion-pair activation mechanism.

Method of molding plastic semiconductor packages

In the manufacture of semiconductor packages having molded plastic bodies, the plating of all of the surfaces of the molding tool that comes into contact with the molten resin during molding with a nodular thin dense chromium ("NTDC") coating prevents the surfaces from adhering to the package body and ensures good package release, without formation of cracks or craters in the package body. This, in turn, permits the amount of both release agents and adhesion promoters used in the molding compound to be substantially reduced, or eliminated altogether, thereby resulting in a package body having improved strength and adhesion with the components of the package, and hence, an improved resistance of the package body to the propagation of cracks and its subsequent penetration by moisture.
