Keeping food in good condition for a long time has always been a challenge for the human race. From the earliest prehistoric times, new methods of food preservation have always been sought. Today we will explain how a system that is widely used today is made: aluminium foil..
Aluminium foil is a kitchen element that allows food to be preserved very well. as it protects it from all types of bacteria. Moreover, as it is metallic, if we put it in the fridge, it keeps the cold better. Its manufacture is very simple as it is essentially based on increasingly refining an aluminium plate giant. Thus, at the end of the process, a sheet about one metre thick and two metres long becomes a sheet about 2 mm thick and approximately 13 kilometres long.
Here we offer you a video about the whole manufacturing process explained in detail.
