Aluminium is used for packaging as it is highly malleable: it can be easily converted to thin sheets and folded, rolled or packed. 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, including long-life packs 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 life pet foods.Because of its brilliant impermeability to water vapour and water, aluminium foils help to store food for prolonged time periods. Moreover, because of this wonderful property, aluminium helps to maintain the freshness of foods over long time periods.

The Need for Food Packaging:-
Today, the packaging is an essential part of the food supply chain. Food safety and freshness are ensured from the factory to the dinner table. Food packaging has progressed from merely serving as a container for food to now being able to maintain the quality of that food. A lot of packaging is still just a container, but it has been created to keep food qualities safe. Barriers to oxygen, moisture, and flavor are among them. A Good Packaging has made it possible to enjoy various food items all the year that would not have been available without it.
The industrial revolution had a significant impact on the design and development of food packaging. Packaging progressed as machines took over as the major way of making things, and production became faster and more efficient.
Going Green and Increased Concentration on Nutrition
Due to low-quality packaging and inefficient production techniques, a great deal of packaging waste was accumulating around the globe. This packaging badly impacted the environment and caused a large proportion of fresh and frozen food products to spoil and be discarded. There are greater efforts to utilize recyclable materials or materials created from recycled items.
Why Aluminum Foils are being Used for Packaging:-
