ABSTRACT:
A thermoplastic tube, and method for forming such a tube, has a tube body portion formed from an inner layer of thermoplastic material, a barrier layer, and an outer layer of thermoplastic material. The outer layer does not extend completely about the periphery of the tube body and a strip of thermoplastic material having the same composition as the inner layer, fills each gap in the outer layer to form a smooth surface about the tube. The strip may be transparent or of a color different than the color of the outer layer. In a preferred tube, a first layer of adhesive material is provided between the inner layer and the barrier layer, and a second layer of adhesive material is provided between the barrier layer and the outer layer and strip.
