The shiny crisp packets and sweet wrappers are made with a piece of aluminium foil sandwiched between two plastic films - the aluminium is used to make the packet more oxygen-proof, this is key because oxygen makes the shelf life of most food go down meaning that the food will go off if exposed to too much oxygen so by making these oxygen proof bags ands wrappers if is increasing the shelf life of the food.
