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. Collapsible tubes are made from aluminum, 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 majority of medical creams and ointments are marketed in collapsible tubes made from aluminium or plastics which retain their original shape after use, or special laminates based on aluminium foil.
The growth in aluminium consumption is focused on Asian region which is supported by strong public policies by respective governments. The main primary producers of aluminium are located in China, Russian Federation, North America, Latin America, Western Europe, and Australia. India is an important player in the aluminium sector, especially because of its abundant bauxite reserves. India has bauxite reserve base of 1.44 billion tonnes and reserves of 0.77 billion tonnes. The packaging industry is estimated at Rs 150 bn and is growing at 14-15% annually. Thus, due to demand it is best to invest in this project.
