Question

Assertion :Aluminium foils are used in packaging. Reason: Aluminium foil acts as a total barrier to light and oxygen (which causes fats to oxidise or become rancid), odours and flavours, moistness, and germs, and so it is used broadly in food and pharmaceutical packaging.

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Aluminium foil (or aluminum foil) is aluminium prepared in thin metal leaves with a thickness less than 0.2 millimetres (8 mils); thinner gauges down to 6 micrometres (0.24 mils) are also commonly used.
Aluminium foil acts as a total barrier to light and oxygen (which cause fats to oxidise or become rancid), odours and flavours, moistness, and germs, and so it is used broadly in food and pharmaceutical packaging. The purpose of aluminium is to make long-life packs (aseptic packaging) for drinks and dairy goods, which allows storing without refrigeration. Aluminium foil containers and trays are used to bake pies and to pack takeaway meals, ready snacks and long lifepet foods.
