Food Grade Aluminum Foil Food Wrapping Paper
Food packaging bags are not simply made of aluminum foil, but are made of composite materials. This composite material is made of aluminum foil and nylon. Some are made of four-layer co-extruded film. In the case of food, it is often a multi-layer composite material.
Aluminum foil packaging can also be used for food packaging because of its high ductility: it can be easily converted into thin sheets and folded, rolled or packaged. Aluminum foil can completely block light and oxygen (causing fat oxidation or decay), smell and aroma, moisture and bacteria, so it can be widely used in food and pharmaceutical packaging, including long-life packaging (aseptic packaging) packaging), for beverages and milk Products can be stored without refrigeration. Aluminum foil containers and trays are used for scones, packaging take-out meals, ready-to-eat snacks and long-life pet food.
Isolation:
Aluminum foil packaging is widely used for radiation shielding (barrier and reflectivity), heat exchangers (heat conduction) and cable lining (barrier and conductivity). The thermal conductivity of aluminum foil makes it a common accessory in waterpipe smoking: a perforated aluminum foil is often placed between the coal and the tobacco, so that the tobacco is heated without direct contact with the burning coal.
cooking:
Aluminum foil is also used for grilling delicate foods such as mushrooms and vegetables. Wrap the food in aluminum foil and place it on the grill to prevent moisture loss, resulting in a less attractive taste.
Like all metal objects, aluminum foil will react, so put it in the microwave. This is because the electromagnetic field of the microwave induces current in the foil and generates a high potential at the tip of the foil. If the potential is high enough, an arc will occur in the lower potential area, and even in the air around the board. Modern microwave ovens are designed to prevent microwave energy reflection from damaging the cavity magnetron and provide aluminum packaging for microwave heating.
