Abstract: A material includes a first film layer that carries an electric charge, a second film layer secured to the first film layer to form a pocket and a volatile substance disposed in the pocket.

Abstract: A method of producing an electrically charged film includes the steps of forming a molten thermoplastic material into a web, electrically charging the web while the web is at a temperature substantially at or above a solidification temperature thereof, cooling the web below the solidification temperature thereof after charging and winding the web into individual rolls immediately following the cooling step.

Abstract: A polymer film comprises a composition having either a polyolefin or a polyamide as a major component. The film has an Elmendorf tear value parameter of about 200 g/mil or less, a thickness greater than about 0.5 mils. The film has a melt flow index between at least about 2 g/10 min. and less than about 17 g/10 min. and further includes a filler to achieve the 200 g/mil tear value parameter. Alternatively, the film has a melt flow index of at least about 17 g/10 min and need not include a filler. The film is substantially unstretched in the transverse direction. The film may be charged. A method of producing a film is also disclosed.

Abstract: A structure includes a film having a pair of opposed surfaces wherein the film is liquid impermeable and electrically charged and an arrangement carried by the film and having first and second compartments separated from one another by a rupturable wall. First and second compositions are disposed in the first and second compartments whereby the rupturable wall may be ruptured to permit mixing of the first and second compositions.

Abstract: A method of protecting a substantially horizontal surface includes the steps of supplying a liquid impermeable film wherein the film carries an electric charge and trimming the film to a desired size. The trimmed film is applied to the substantially horizontal surface such that the film is retained thereon by the electric charge carried by the film and an object is placed on the trimmed film.

Abstract: A material comprises a liquid impermeable, electrically charged film and a volatile substance carried by the film.

Abstract: A film material includes a pair of opposed surfaces wherein the film is preferably electrostatically charged and at least one of the surfaces is adapted for processing of an item thereon.

Abstract: A material includes a first film layer that carries an electric charge, a second film layer secured to the first film layer to form a pocket and a volatile substance disposed in the pocket.

Abstract: A processing method comprises the steps of providing an electrostatically charged film, placing the electrostatically charged film on a surface such that the film is electrostatically attracted to the surface and processing an item on the film.

Abstract: A dispensing system is provided for two, constituent, fluent materials which are stored separately and then combined in a dispensing process to form a combination product. The dispensing system includes a container having at least two interior storage chambers, and each chamber has a separate discharge opening. Associated with each discharge opening is a separate, flexible valve. Each valve has an initially closed dispensing orifice which opens in response to a differential between the pressure acting against the side of the closed valve facing toward the associated discharge opening and the pressure acting against the side of the closed valve facing away from the associated discharge opening. In a preferred embodiment, a top is provided downstream of the valve. The top is movable between (1) a close position to occlude a dispensing flow path downstream of the valves, and (2) an open position which permits flow to be discharged from the system.
