PACKING
Glass tubes are layered into bundles with a square or rectangular cross-section. They are packed into the geometrically tightest space and then covered at each end with transparent shrink film. Then they are packed into carton. This means that no movement of the tubing is possible during transportation, so that the package is more stable and reliable. The shrinks film at each end of the bundle cover each tube and provide the very best protection against contamination.
