    Abstract: A METALLIZED FILM WHICH IS LITTLE BROKEN NEAR THE MARGIN EVEN IF HIGH VOLTAGES SPECIFIED TO BE APPLIED BY SAFETY STANDARDS FOR CAPACITORS ARE APPLIED AND CAN BE USED TO PRODUCE A VERY HIGHLY SAFE CAPACITOR IS DISCLOSED, TOGETHER WITH A PRODUCTION METHOD THEREOF AND A CAPACITOR WITH EXCELLENT PERFORMANCE. THE PRESENT INVENTION RELATES TO A METALLIZED FILM, COMPRISING A DEPOSITED METAL LAYER ZONE DESTINED TO BE AN ELECTRODE WITH A SURFACE RESISTANCE OF 1 W/SQ. TO ABOUT 15 W/SQ., A MARGIN WITH A SURFACE RESISTANCE OF 1 X 1010 W/SQ. OR MORE, AND A 0.02 TO 1 MM WIDE BOUNDARY ZONE EXISTING BETWEEN THE DEPOSITED METAL LAYER ZONE AND THE MARGIN AND CONTINUOUSLY DECREASING IN THE THICKNESS OF THE DEPOSITED METAL LAYER FROM THE DEPOSITED METAL LAYER ZONE TO THE MARGIN, AT LEAST ON ONE SIDE OF A HIGH POLYMER FILM. THE PRESENT INVENTION ALSO RELATES TO A CAPACITOR PRODUCED BY WINDING INTO A ROLL THE METALLIZED FILM OR STACKING IT WITH OTHER IDENTICAL METALLIZED FILMS.FIGURE 5

    Abstract: A multilayered film which is excellent in quality and processability and can be safely and stably produced. The film is characterized in that it comprise s a substrate and, formed thereon, a polymer resin layer and a vapor-deposited film of a metal and/or a metal oxide and that at least 80 wt.% of the polyme r resin layer is accounted for by a polymer of an unsaturated compound having at least two ethylene bonds and/or acetylene bonds per molecule and having neither an acrylic nor methacrylic group. The film having a vapor-deposited metal coating is usable as a packaging film having gas-barrier properties, a film for capacitors, etc.

    Abstract: A metallized film suitable for a capacitor comprises a polymer base film and a vapor-deposited layer consisting essentially of Al and Zn, which is formed on the polymer base film. The Al content in the vapor-deposited layer is continuously varied along the direction of thickness thereof such that the Al content satisfies the equation of: (wherein a1 represents Al content in terms of percent by weight based on the total weight of Al and Zn in the interface between the vapor-deposited layer and the polymer base layer; a2 represents Al content in terms of percent by weight based on the total weight of Al and Zn at the center in the direction of thickness of the vapor-deposited layer; and a3 represents Al content in terms of percent by weight based on the total weight of Al and Zn in the surface of the vapor-deposited layer).

    Abstract: The present invention is aimed at providing a multilayer film having high quality and high processability which can be safely and stably produced. Such object of the present invention can be achieved by a multilayer film comprising a base material, a polymer resin layer and a metal deposited layer and/or a metal oxide deposited layer provided thereon, wherein the polymer resin layer contains a polymer produced by polymerization of an unsaturated compound having two or more ethylenic bonds and/or acetylenic bonds in one molecule and having neither acrylic group nor methacrylic group, in an amount of 80 % by weight or more based on the polymer resin layer. The multilayer film according to the present invention can be used for a metallized packaging film having gas barrier properties or a metallized film for a capacitor and the like.

    Abstract: In plasma-treating the inner surface of a plastic tube, the invention provides a treating method which ensures stable treatment under readily operative conditions. The present invention relates to a method comprising the steps of placing a plastic tube inside an electrically insulating tube wherein the difference between the inner diameter of the insulating tube and the outer diameter of the plastic tube is less than 2 mm, letting a gas into the plastic tube, keeping the inner pressures of both tubes at a reduced pressure, applying a high voltage across electrodes disposed outside the electrically insulating tube to initiate and sustain discharge inside the plastic tube and thus plasma-treating the inner surface of the plastic tube.
