Plastic leader

 Usually, white or yellow leader tape in between songs on a master tape. Plastic leader can pick up static electricity, which can create clicks or pops on the master tape. For that reason, paper leader is generally used on masters. There are special types of plastic leaders, made of an anti-static base, that are used for archival storage where paper leader, which changes shape in varying humidity and deteriorates with age, will not suffice.
