4. ALUMINIUM Aluminium tube caps and closures are generally threaded, as is the nozzle. The tube is hermatically sealed and nearly grem-free due to the high temperatures during the production process. Aluminium tubes are produced by impact extrusion from a small round blank. Shuhaiba Backer

5. Designs can be printed on to the tube using wet-in-wet offset printing method. The filled content can be squeezed out by finger pressure. Aluminium tubes are especially suitable for the packaging of highly perishable contents. APPLICATIONS : Used for cosmetics, pharmaceuticals, food paint and technical products Shuhaiba Backer

7. PLASTIC Tubes can also be produced in plastic, most commonly polyethylene. Plastic tubes are popular for cosmetics such as hand creams, and also some foodstuffs. The plastic tube retains its shape after each squeeze unlike laminate tubes such as toothpaste tubes. Shuhaiba Backer

8. Plastic tubes can be highly decorated or have a special additive such as soft touch to make the tube more appealing during use or at the point of sale. Plastic tubes are produced by extrusion. Tube printing using specialized printing machines such as silk screen printing applies the desired decoration. Multi- layer plastic tubes have become increasingly popular; they isolate the contents better from the air, allowing them to be used for a wider range of products, such as food. Shuhaiba Backer
