when it comes to the packaging of sensitive goods, the collapsible aluminium tube provides exclusive advantages &ndash today as well as in the future. the collapsible aluminium tube has outstanding barrier properties, and it is the ideal packaging to constantly protect a product against foreign odour, uvlightsunlight, and loss of aroma and perfume, while the tube itself is completely scentneutral and can be clean and encased with an inert internal lacquer. aluminium prevents the penetration of oxygen on the permanent basis. this important barrier property makes the tube made up from aluminium a well established and most appropriate packaging in the pharmaceutical, food and cosmetic markets. collapsible aluminium tubes are made up of 99.7 pure aluminium, which makes the recycling procedure economically viable and easy. from a small disk of aluminium, the tube is created by impact extrusion. this small disc is called a slug. the size of the slug is according to the required tube dimension and resolves either a closed tube with a casing over the orifice or an open tube. to make the tubes sterile and pliable, in an annealing oven, those tubes are heat treated. if needed, optional internal lacquering can offer safety against any contact connecting the internal aluminium tube surface and the content. to highlight their customer&rsquos unique artwork, an external base coat layer offers a good background, printed in up to 3 colours. source of information httpwww.firstaluminiumnigeriaplc.comindex.phpoptioncomcontent&viewarticl…
