The two-user responsive work-bench: Support for collaboration through inde-pendent views of a shared

A packaging material comprising a continuous length of flexible tubular material having a multiplicity of folds alternating at opposite ends to form concentrically superimposed layers of annular plies of the material. The superimposed layers can be staggered in the axial direction or aligned. In one embodiment, the end of the material which is closer to the outer layer is folded over the plies and extends through the interior of the inner sheath.
