Abstract
Official abstract text for this publication.
Disclosed is a surface conductive laminated sheet which comprises a base material layer containing an ABS resin as a main component, and a surface layer laminated on the surface of at least one side of the base material layer. In the laminated sheet, the ABS resin in the base material layer includes a composition made of 5-15 mass % of vinyl cyanide monomer, 45-65 mass % of diene-based rubber, and 50-20 mass % of aromatic vinyl monomer, and includes a graft rubber having a graft rate of 50-80%. The graft rubber has a mass average molecular weight (Mw) of a graft chain of 18,000-56,000, and/or has a volume average particle diameter of 0.3 to 2.0 μm. By using the laminated sheet, it is possible to obtain an electronic part packaging container, such as carrier tape etc., which has extremely few punch burrs regardless of the type of forming apparatus when punched by means of a slit method or embossing.
