What is required for quality packaging?
 * __ Aluminium Packaging __**
 * Impermeable
 * Non-toxic
 * Recyclable
 * Light weight
 * Cheap to make
 * Hygienic
 * Corrosion resistance
 * Retaining of product flavour
 * Non-tainting
 * Thermal Conductor
 * Flexible
 * Little pollution sourced from its manufacture
 * Easy accessibility of product
 * Little potential for injury
 * **__ Pros __**
 * High-level corrosion resistance.
 * Provides optimal protection properties offering impermeable metal barrier to light, ultra-violet rays, water vapour, oils and fats, oxygen and microorganisms.
 * Hygiene
 * Non-tainting
 * Retains the products flavour
 * Retains the products flavour


 * Scientific backing **
 * __ Light-weight __ – It has a density of 2.70g/cubic cm (compared to iron used in steel 7.86g/cubic cm) light, this also cuts down transport costs.
 * __ Impermeable __ – It uses a barrier function which keeps out air, light, liquid and microorganisms. Preserving food contents, cosmetics and pharmaceutical products using this technique.
 * __ Thermal Conductor __ – Transfers heat 2.4 times faster than iron. Combined with the fact that very thin sheets can be produced, means heat is lost and gained through aluminium very quickly. Ideal for cooking and a cold drink container.
 * __ Flexible __ - It can be rolled into extremely thin foil & can be cast, joined & still retain much of its strength.
 * __ Recyclable __ – Aluminium is 100% recyclable & uses only 5% of the energy used to make original product. Aluminium drinking cans are the most recycled packaging product in the world.

 * Scientific backing **
 * __ Potential for injury __ – once an aluminium can is opened, interior poses injury because ofsharpedges – risk not found in other types of food-packaging materials. The ‘British Medical Journal’ notes that injuries sustained from opening aluminium cans may need stitches, sterile dressing & antibiotics.
 * __ Pollution __ – Although Aluminium is recyclable, the ‘Container Recycling Institute’ claims that half of all cans end up in incinerators or landfills – resulting in the need of additional cans to be made. Aluminium smelting gives sulphur dioxide & nitrogen dioxide which can result in smog & acid rain. Can manufacturers who strip-mine bauxite ore get enough alumina to manufacture cans. Creating 1 tonne of Aluminium cans leaves 5 tons of liquid waste material, that can pollute soil and groundwater.
 * __ Environmental Conservation Issues __ – 1/3 of all aluminium manufacturing plants use coal to produce their product, being cans. Another 10% rely on other fossil fuels, such as oil and natural gas. These fuels, though common and useful in manufacturing, are relatively scarce. Therefore, as we exhaust the earth’s amount of these we must find a new way of carrying this act out.
 * __ Accessibility __ – Aluminium cans preserve food for long periods of time, yet without a can opener you cannot gain access to the preserved food inside. Injury may be caused if attempts are of alternative methods fail.
