Упакоўку з алюмініевай фальгі таксама можна выкарыстоўваць для ўпакоўкі харчовых прадуктаў, таму што яна вельмі пластычная: яго можна лёгка ператварыць у шматкі і скласці, згарнуць або загарнуць. Алюмініевая фальга цалкам блакуе святло і кісларод (што прыводзіць да акіслення або распаду тлушчу), пах і водар, вільгаць і бактэрыі, і таму можа шырока выкарыстоўвацца ў харчовай і фармацэўтычнай упакоўцы, уключаючы ўпакоўку з доўгім тэрмінам службы (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), цеплаабменнікі (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.
