Zusammenfassung:	PROBLEM TO BE SOLVED: To improve protective properties of a content in the case of using as a packaging container, by specifying surface specific resistance value of a composite plastic sheet and composition of polystyrene resin for constituting conductive resin composition to be laminated on a base material of the sheet. SOLUTION: In the composite plastic sheet obtained by laminating conductive resin composition containing 5 to 50 pts.wt. of carbon black to 100 pts.wt. of polystyrene resin on one side surface of both surfaces of polystyrene resin sheet base material, surface specific resistance value of the sheet is 10 to 10 Ω, and the polystyrene resin contains 5 to 40 pts.wt. of resin containing methyl methacrylate polymer or copolymer of ethylene and methyl methacrylate to 100 pts.wt. of polystyrene resin as main components. And, the polystyrene resin may be general polystyrene resin, impact resistant polystyrene resin or mixture of them.
