Patent ID: 7268186

Claim:
A sheet for a carrier tape, having at least one layer comprising (I) a block copolymer comprising a vinyl aromatic hydrocarbon and a conjugated diene, (II) a non-rubber-modified vinyl aromatic hydrocarbon polymer, and (III) a rubber-modified vinyl aromatic hydrocarbon polymer, wherein the vinyl aromatic hydrocarbon polymer block in the block copolymer (I) has a peak molecular weight of from 30,000 to 80,000, and said vinyl aromatic hydrocarbon block has a half-width in its molecular weight distribution curve of from 1.3 to 2.8, said sheet for a carrier tape has a vinyl aromatic hydrocarbon content of from 75 to 95 wt % and a vinyl aromatic hydrocarbon polymer component content of from 65 to 85 wt %.
