Since it is used as a sheet and wrapped around a wire harness mass production line with a fast line tact, it does not have enough wrapping power for the wire harness to be included, or it is thick when wrapped around the wire harness. Sometimes it becomes too much.

Therefore, during movement / transportation of the wire harness, the packaging sheet is misaligned, the branch lines, connectors, etc. protrude and "blunder", or the pile-shaped packaging sheet becomes difficult to pass through the through hole of the vehicle body. There is.

The present invention provides a pile-type packaging sheet for a wire harness that solves the above-mentioned drawbacks of the prior art.
