A collapsible tube is defined as a cylinder of pliable metal that can be sealed in such a manner that its contents, although readily discharged in any desired quantity, are protected from contact with air or moisture. Products so packaged must flow under pressure low enough not to damage the tube. Collapsible tubes are widely used as handy flexible packages for pastes and semi-liquids. As the tube is flattened out to expel its contents, the capacity of the tube is proportionately reduced without the introduction of air and the material in the tube does not suffer any deterioration. These are fabricated readily, and are strong enough to withstand processing, they are light in weight, easy to handle, and fairly cheap. They can be handled on high speed machines. This type of cans are properly sealed after filling the measured quantity, to keep the customer's faith on sealed material sealing also prevents dusting and other bad materials to mix with the product. Collapsible tubes are made from aluminium, tin coated lead, or lead tin alloy by cold extrusion. They consist of three parts, the main tube, a shoulder to one end of which a screened nozzle with orifice is fitted, and a molded cap to close the orifice, sometimes application of various design are attached to the nozzle with the help of mechanical or hand operated filling machines, the end is sealed by folding and crimping. Collapsible tubes were initially introduced for packing artists oil color. However, now its use has spread for packing a wide variety of products. These tubes are used for filling tooth paste, shaving creams, ointment and inks, etc. It is hygienic, non-toxic and non-absorbent and has a high heat transfer rate. Consequently, aluminium is an ideal tubing material for several process industry applications. Aluminium tubes look attractive in its natural state and its appearance can be further enhanced by a variety of finishes. In the packaging sector, aluminium is used in foils, cans, collapsible tubes and bottle caps. Hence, globally, the growth of the packaging industry hinges on growth in sectors like foods, beverages, and medicines. Any entrepreneur venture into this field will be successful.
