Disclosed herein is a sealing apparatus comprising a moisture barrier that engages with a filament spool to create a moisture-resistant enclosure for housing a filament on said spool, and a passageway in said sealing apparatus so that the remaining filament can exit sad sealing apparatus during use. Also disclosed is a method for preparing and packaging the filament and sealing apparatus.

A wire reel is detachably provided in a housing chamber of a binding machine body which binds a reinforcing bar. The wire reel includes a cylindrical hub portion which winds a wire, and a pair of parallel flanges overhanging outward from both external peripheral ends of the hub portions. A side wall inside the hub portion is formed of light-transmitting portions which allow the light from a transmissive photosensor provided in the binding machine body to be transmitted therethrough.
