  • Sheet for carrier tape
    Patent number: 7268186
    Abstract: The present invention relates to 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 type hydrocarbon polymer, and (III) a rubber-modified vinyl aromatic type hydrocarbon polymer, wherein the peak molecular weight of the vinyl aromatic hydrocarbon polymer block in the block copolymer (I) is from 30,000 to 80,000, the half-width in the molecular weight distribution curve of the vinyl aromatic hydrocarbon block is from 1.3 to 2.8, the vinyl aromatic hydrocarbon content in the sheet for a carrier tape is from 75 to 95 wt %, and the content of the vinyl aromatic hydrocarbon polymer component is from 65 to 85 wt %.
