One of the most popular aluminum products proves to be aluminium foil used for wrapping food. Aluminium foil, different from plastic or paper bags, combines properties of good flexibility, favorable strength and healthy material. People around the world have got used to wrap cooked food like fried chicken with aluminium foil because of its advantages overshadowing other packaging materials.
Aluminium foil used for wrapping food shows good strength in comparison with paper. Although it’s healthier to wrap a pancake sandwich with a small paper bag, the bag breaks soon after oil gets into it. In China sandwiches like this never lose popularity among college students and white-collar workers. It’s really embarrassing, however, for an attractive girl walking on the street to have food like sandwiches. She usually takes a sandwich home or to office as breakfast, but what if the paper bag cracks on the way? To solve the problem a plastic bag is used outside the paper bag. In fact, if sellers chose aluminium foil bags, things would get easier. In addition, aluminium foil used for wrapping food neither contains nor produces any harmful elements at high temperature of cooked food. With increasingly severer problem of food safety, it turns out to be an excellent choice as wrapping material for take-away food.
Except for take-away food, aluminium foil used for wrapping food can be used as covering materials for other foods as well. Bakers put dough mixed with egg and sugar into small aluminium foil containers to make cakes. The foil won’t be deformed or burned in the oven. At barbecues people wrap fresh fish, meat, vegetables and even corn on the cob and then place the food on the barbecue stand. Food gets cooked evenly wrapped in aluminium foil which protects it from dust, insects and other alien materials.
