<p>The invention provides conductive composite sheeting which has little difference in physical properties between the lengthwise and widthwise directions and exhibits high rigidity and high flexural strength and which can be easily thermoformed into trays or embossed carrier tape. The sheeting is one comprising at least one base layer (A) made mainly of both a polystyrene resin and an ABS resin, at least one reinforcing layer (B) made mainly of an ABS resin, and at least one surface skin (C) made mainly of a polystyrene resin containing a conductive filler wherein at least one of the surfaces is constituted of the skin (C). It is preferable that the surface skin (C) be made of a composition comprising 100 parts by mass of a polystyrene resin and 2 to 100 parts by mass of carbon black, while the base layer (A) and the reinforcing layer (B) contain specific amounts of a styrene/butadiene /butylene/styrene block copolymer resin or the like.</p> |
