The bulk case is the packaging material for electronic components used in the bulk feeding system, and may contain electronic components in bulk. Unlike taping packaging, however, electronic components need not be lined up. The case has a volume of 110 x 36 x 12mm, and can contain a large number of electronic components.
In 1996, a bulk case standard was revised by EIAJ (ET-7201A).
