Abstract: A thermoformed plastic package made of a single piece of formed plastic sheeting folded upon itself along a hinge band. The back and front sections form an enclosure, preferably for a tape roll, and have contacting portions which include flat areas and interlocked undercut mating areas which extend from a first position near the hinge around the enclosure to a second position near the hinge, and preferably along the hinge as well. The hinge band preferably includes a center portion narrower than the total width of two side portions therealong, and serves to draw the face-to-face sections of the package together along the hinge. A tape channel extending from the enclosure provides frictional engagement tape being dispensed.
