Aluminium Foil as a Food Packaging Material in Comparison

ウェブ  Aluminium foil is an important material in laminates and has wide application in food packaging. Its barrier function against the migration of moisture, oxygen and other gases, and volatile aroma, as well as against the impact of light is generally higher than any plastic laminate

The Effect of Thickness of Aluminium Films on Optical

ウェブ  Aluminium foil which is currently used as the reflecting surface on solar cookers is quite easy to damage and is also known to darken when exposed to moisture. This creates wear of aluminium foil leading to the formation of small pinholes in it when it comes in contact with different metals or food that is highly salted or acidic [
