Abstract: The present invention relates to a method of making a film composition with an improved uniformity of active composition. The invention includes a method including the steps of forming a flowable film composition comprising an edible water-soluble polymer, a polar solvent and a particulate active suspended therein, where the ratio of solids to liquids is at least about 95 to about 5 and where the composition comprises a mixture having compositional uniformity per unit volume; directing the flowable film composition to a transfer trough, the transfer trough including a first rotating roller and a movable transfer substrate upon which to form the film; and maintaining uniformity of the flowable film composition during the residence time in the trough by maintaining the rate of composition entering the transfer trough and the level of the flowable film composition in the transfer trough at a substantially constant level. Methods of administering the active are also contemplated.

Abstract: A method and system for continuously preparing a solvent cast film having a secondary component are disclosed. The method includes continuously providing a pressurized stream of polymer solution, continuously combining a fluid stream including a secondary component with the pressurized stream of polymer solution, homogeneously mixing the combination of polymer solution and fluid stream in-line, continuously applying the resulting homogeneous mixture of polymer solution and secondary component to a continuously moving surface, and then evaporating solvent from the mixture to form a polymeric film.

Abstract: A method and system for continuously preparing a crosslinked, solvent-cast film are disclosed. The method includes continuously providing a pressurized stream of polymer solution, continuously combining a fluid stream including a crosslinking agent with the pressurized stream of polymer solution, mixing the combination of polymer solution and fluid stream in-line, continuously applying the resulting mixture to a continuously moving surface, and then evaporating solvent from the mixture to form a polymeric film.

Abstract: A photoluminescent retroreflective sheeting for use in structures when a power outage occurs. Guidance systems are made from this sheeting to mark exits and escape routes as well as possible hazards and safety devices. The novel sheeting includes photoluminescent properties that glow in the dark as well as retroreflective properties that retroreflect light incident upon the same sheet such that only one sheet has to be used rather than individual sheets with separate properties.

Abstract: A retroreflective unitary laminate material having an acrylic layer on which a sign legend is printed and which is covered by an ultraviolet absorbent overlay that has poor affinity for paint and low surface tension thus protecting the printed sign from deterioration due to weathering and enabling the sign to be readily cleansed without damaging the printed signs, and minimizing water beading on the sign front face.
