Which mineral is used extensively in the packaging of food products?

  1. Mica

  2. Aluminium

  3. Chrome

  4. Asbestos
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

 Commonly used to make cans, foil, and laminated paper or plastic packaging, aluminum is a lightweight, silvery white metal derived from bauxite ore, where it exists in combination with oxygen as alumina. Magnesium and manganese are often added to aluminum to improve its strength properties (Page and others 2003). Unlike many metals, aluminum is highly resistant to most forms of corrosion; its natural coating of aluminum oxide provides a highly effective barrier to the effects of air, temperature, moisture, and chemical attack.
