Sector Focus:Aluminium Foil

Aluminium foil can be found in kitchen drawers and cabinets in many homes. Originally, it came as a replacement for Tin foil after World War II; not only was it cheaper and more durable, it also helped to avoid the slight ‘tin taste’ of food that was wrapped in Tin foil. Not long after a patent for the continuous rolling process was taken out in Switzerland, Toblerone began wrapping its chocolate bars with Aluminium foil. This solidified its wide-ranging use with food and confectionary!

Made from Aluminium of standard purity (about 99 %), or high purity (above 99.99 %), Aluminium foil is produced in many widths and strengths, most commonly in sheets of less than 0.1mm. Being pliable, Aluminium foil can be easily bent, folded and wrapped around objects, making it a top choice for food packaging and protection. Its unique barrier properties provide a total block to light, moisture and aroma, which is a reason why it’s so popular in a range of markets, from food and beverage to pharmaceuticals.

The properties of Aluminium foil mean it’s:

• Durable 
• Non-toxic 
• Resistant to chemical attack
• Electrical and non-magnetic shielding 
• Able to block light, moisture and aroma
