ABSTRACT:
A tubular core and associated method of manufacture are provided. The tubular core includes at least one inner ply and at least two plastic plies disposed thereon. The inner ply, which can be paper or plastic, has an inner surface upon which identifying indicia are printed, for example, before the tube is formed and while the inner ply is in a flat configuration. The first and second plastic plies are disposed on the inner ply and adhered so that the second plastic ply substantially covers the inner ply and the first plastic ply.
