Abstract: A carrier tape, cover tape or static shielding bag for transportation of electronic components is constructed of polymers and carbon nanotubes being between 0.01% and 3% by weight. The carbon nanotubes may have any number of walls and any desired size of diameter dimension which is less than approximately 100 nm. The carrier tape, cover tape or bags including the carbon nanotubes have a static dissipative range measured between 1×105 and 1×1012 Ω/sq and a light transmittance value of between 60% and 90%. The carrier tape, cover tape or bags including the carbon nanotubes reduce surface defects, high density entanglements and agglomerations. The static shielding bags including the carbon nanotubes may be formed as sheets which are manufactured into a desired size of bag.
