Aluminum has become the ruling material in packaging due to its versatile characteristics. The most significant is its recyclable nature and flexibility. It has gained prominence over other materials like plastic and glass over the period of time as it exhibits far superior properties, apt across various applications and uses.
Being lighter and sturdier than glass, it flaunts few inimitable features. It is lightweight, easy to shape, good conductor of electricity and heat, is stable and resistant to organic acids. As it is available in abundance, its use is convenient and easily obtainable.
Aluminum packaging provides protection from ultra-violet rays, water vapour, oils and fats, oxygen and micro-organisms. When used to package sensitive products such as pharmaceuticals, cosmetics or food, aluminum is hygienic, non-toxic, and retains the product’s flavour.
An aluminum barrier also plays the essential optimal protection properties by offering an impermeable metal barrier to light, one of keeping the contents fresh and protecting them from external influences, thereby guaranteeing a long shelf-life.
