Aluminum is a highly reflective material that reflects the thermal radiation emitted by the human body, with a thermal reflection efficiency of up to 90%. This effectively reduces the body's cooling rate. Because aluminum belongs to the metal, it is easier to tear, the intensity is not high. Therefore, the main purpose of the composite plastic film increases the toughness and strength of the emergency blanket.
