Ang aluminum foil packaging pwede sab gamiton para sa food packaging tungod kay malleable kaayo: kini dali nga mabag-o sa mga tipik ug mapilo, giligid o giputos. Ang aluminum foil hingpit nga nagbabag sa kahayag ug oksiheno (nga moresulta sa fat oxidation o pagkadunot), baho ug kahumot, umog ug bakterya, ug busa kaylap nga magamit sa pagputos sa pagkaon ug parmasyutika, lakip ang long-life packaging (aseptic packaging), for beverages and dairy products that can be stored without refrigeration. Aluminum foil containers and trays are used for scones, packaged takeaway meals, ready-to-eat snacks and long-life pet food.
Aluminum foil packaging is widely used for radiation shielding (barriers and reflectivity), heat exchangers (heat conduction) and cable linings (barriers and conductivity). Aluminum foil’s thermal conductivity makes it a common accessory in hookah equipment: a piece of aluminum foil with holes is often placed between the coal and tobacco so that the tobacco is heated without coming into direct contact with the burning coal.
Aluminum foil is also used for grilling delicate foods such as mushrooms and vegetables. Wrap food in aluminum foil and place it on the grill to prevent moisture loss, which can lead to a less appealing texture.
Like all metal objects, aluminum foil will react and put it in the microwave. This is because the electromagnetic field of the microwave induces an electric current in the foil and creates a high electrical potential at the tip of the foil. If the potential is high enough, an arc will be generated in areas of low potential, even in the air around the board. Modern microwave ovens are designed to prevent the reflection of microwave energy from damaging the cavity magnetron, and aluminum packaging for microwave heating is provided.
