Have you ever wondered how aviation aluminum foil sheet can keep food warm, or is it safe to store food in aviation aluminum foil sheet for a long time? Whether it's office lunch or college lunch, planning a picnic or traveling, most of us will wrap our homemade food in aviation aluminum foil sheet and take it with us. But have you ever wondered how aviation aluminum foil sheet can keep food warm, or is it safe to store food in aviation aluminum foil sheet for a long time?
Aviation aluminum foil sheet is made of aluminum (as the name suggests). Aluminum has reflective properties and can act as a barrier to light and oxygen. As a result, the aluminum foil sheet reflects heat energy back to the food, maintaining the inherent aroma, moisture, and flavor of the food. Aviation aluminum foil sheet is usually used for packaging perishable food and dairy products, and it is also used for longer storage of food. GXFlight's aviation aluminum foil sheet is used for cooking, freezing, baking and storage. Optional color box packaging or customer-designed PP bag packaging is available. It has excellent anti-penetrant property to water vapor and gas and extend the shelf life of food. Compared with many other packaging materials, it produces less waste and is non-toxic and hygienic. It is oil-proof and does not absorb liquids.
How does aviation aluminum foil sheet work? Aviation aluminum foil sheet can keep food warm, but placing aviation aluminum foil sheet directly on objects or food does not help much. The reason behind this is that if the foil is in contact with an object, the heat energy will move in the foil itself and may disappear, but if the foil is placed far away from the food, it can correctly reflect the heat energy and maintain the freshness of the food. Therefore, in order to avoid contact between aviation aluminum foil sheet and food, you can add several layers of butter paper to make an air bag, and then add packaging to the last layer of aviation aluminum foil sheet. Since aluminum is a poor insulator (substance that does not allow heat to pass through), in order to make aviation aluminum foil sheet more effective, place it (food wrapped in aviation aluminum foil sheet) in a fiberglass or ceramic Tiffin box. Aviation aluminum foil sheet not only keeps food warm for a long time, but can also keep it cool. It acts as a barrier between oxygen and air, and can transfer heat to cold or frozen food. The most important thing is that aviation aluminum foil sheet helps maintain the temperature of food, whether it is hot or cold.
