<p>PROBLEM TO BE SOLVED: To provide a novel sheet made of a styrenic resin, and excellent in transparency, moldability and rigidity, and suitably usable for packaging an electronic part. SOLUTION: The sheet is constituted by providing a skin layer comprising a styrene/conjugated diene block copolymer and a styrenic resin on at least the single surface of a substrate layer comprising the styrenic resin or the styrene/conjugated diene block copolymer and the styrenic resin. The skin layer contains 51-80 wt.% of the styrene/conjugated diene block copolymer and 49-20 wt.% of the styrenic resin with respect to the sum total of the styrene/ conjugated diene block copolymer and the styrenic resin on at least the single surface of the substrate layer, which contains 0-50 wt.% of the styrene/ conjugated diene block copolymer and 50-100 wt.% of the styrenic resin with respect to the sum total of the styrene/conjugated diene block copolymer and the styrenic resin.</p> |
