Abstract: Styrene resin films having been imparted antistatic properties to both film surfaces and good adhesion properties of the films to envelope paper, and a process for producing the same. In these styrene resin films, the surface tension of the front surface of the film base differs from the surface tension of the back surface owing to a hydrophilic treatment and modifiers having almost the same compositions are applied onto the respective surfaces each in an adequate weight.

Abstract: A non-aqueous battery is provided in a pouchy casing comprising opposing sheets of at least three-layer laminates, each laminate comprising (1) an inner thermoplastic resin layer, (2) a middle metal foil layer, and (3) an outer electrically insulating material layer, wherein the pouchy casing has an elongated, hermetic adhesion area along a periphery of the pouchy casing, and the middle metal foil layer has a peripheral elongated region in the elongated, hermetic adhesion area of the pouchy casing, and at least a pair of terminals electrically connected to the cathode and anode of the battery extends through and protrudes from the terminal-withdrawal sites in the elongated, hermetic adhesion area toward the outside of the pouchy casing, and the battery has at least one of the following features: (i) the peripheral elongated region of the middle metal foil layer has cut-out portions around the terminal-withdrawal sites and (ii) the surface of the peripheral edge of the pouchy casing is provided with electric i
