Emergency blankets, also known as space blankets or thermal blankets, are lightweight, compact sheets made from a thin layer of plastic. They are designed to reflect body heat, helping to retain warmth in cold conditions. These blankets are often used in emergency situations, such as during outdoor activities, natural disasters, or medical emergencies. In addition to providing warmth, emergency blankets can also serve multiple purposes. They can be used as a ground cover, a makeshift shelter, or even as a signaling device due to their shiny surface. Their versatility and portability make them essential items for first aid kits and survival gear.
