The outer shell is usually made from durable materials such as polyester, nylon, or neoprene. The inner lining is often made of aluminum or PVC to provide a waterproof and easy-to-clean surface. The thermal insulation material, usually foam or foil lining, is used to maintain the temperature of the contents inside the bag. The zipper closure ensures that the bag is fully sealed and prevents heat or cold from escaping. Working Mechanisms Lunch bags with thermal insulation work by reflecting and retaining the temperature of the food inside the bag. The thermal insulation material helps to keep the temperature of the contents within the bag, preventing hot air from entering or cold air from escaping. The thermal insulation lining works by reflecting the heat or cold instead of absorbing it. Advanced Technology Advanced technology plays a crucial role in enabling efficient production processes of Lunch bags with thermal insulation.
