Abstract
An improved core for mounting on one or more core engaging elements such as a pair of chucks and a method of making an improved core are provided. The core is adapted to wind and unwind material thereon. The core may comprise a high coefficient of friction coating disposed on the inner surface of the core to improve the core-chuck interaction. The inner surface may be mechanically or chemically treated to improve core-chuck interaction.
