Aluminium is used widely in foil form for packaging at thicknesses of just over 6 to around 150 microns (a micron is one millionth of a metre). The key properties of aluminium as a packaging material are summarised in Table 9.1. One of the most important properties of aluminium as a packaging material is its inertness compared to most metals. As noted earlier, when exposed to air, aluminium forms a transparent oxide layer which prevents further oxidation. As well as being resistant to corrosion, aluminium is non-absorbent and thus an effective barrier against gases and liquid.
High quality food grade color coated aluminium foil 8011 3003 could be used for production of semi-rigid containers and lids for food packaging. Due to its excellent thermal conductivity properties, coated aluminium foil food container is ideal for the reduction of
cooking, cooling and heating. Color lacquered aluminium foil provides high barrier protection against light, gas and contamination, that improves the food conservation. With the colour coated aluminium foil lid, the food could be heated in air furnaces and ensure the preservation of an optimum temperature and a good state of food longer, being light weight and resistant to external agents at the same time.
