The Nature of the Aluminium Collapsible Tubes
Aluminium Tubes has the special property of remaining neutral or inactive when it comes in contact with or other products. It is for this reason that it is one of the most preferred metals that are used in the manufacture of tubes that are used to pack sensitive materials. Besides, this protection is offered over long durations of time.
Aluminium coin shaped rings are first cold rolled and extruded to form a hollow tube or sleeve of the required diameter; it is then cut to the size needed and sealed at one end after the filling process and then folded several times to form a good seal. It is then that a head and shoulders are added at the other end which can be threaded to screw on a cap or a closure if required.
The products are practically germ free during the filling process as the prevailing temperatures at that time are fairly high. There can be unlimited printing designs possible on the outer surface, not only to mention the contents of the Collapsible Aluminium Tube, but to also make them as attractive as possible for effective marketing.
