In the present invention, the infrared ceramic powder contained in the plastic masterbatch generates far-infrared rays beneficial to the human body by absorbing the heat of the human body. Far-infrared ray is a kind of invisible light. Although the development of the effect on the human body is late, it has been proved that it is closely related to the physiological response of the human body, especially the 5.6-15μm band beam, which produces physiological activation on the human body and helps to improve the human body. Regulatory ability has thus attracted great attention from the medical community and is widely used in medical treatment. It is called "fertility light" by experts. Far-infrared rays act on the human body and have three main characteristics: one is radiation, the other is strong penetration, and the third is absorption, resonance and resonance. The surface of the human body accepts far-infrared rays, conducts and penetrates from the surface to the inside, and is absorbed to produce a warming effect, which resonates and resonates with tissue cells in the body, and promotes activity. And because of the warming effect, the microvessels of the human body expand, self-discipline is strengthened, and blood circulation is accelerated. Due to the resonance and resonance, the active response of the cells is enhanced, and the material exchange between the cells and the blood is accelerated, thereby promoting the metabolism of the body. Here it is the principle of far infrared rays acting on the human body. Many diseases are caused by the human body due to blood circulation disorder and poor metabolism. These diseases are generally caused by hypoxia and insufficient supply due to circulatory disturbance, and the metabolism of cells slows down to cause poisoning symptoms. This is the saying that "hypoxia is the source of all diseases". Far-infrared rays act on the human body to produce absorption, resonance and resonance, which promotes the incorporation of various nutrients and therapeutic drugs and the discharge of impurities. It has been clinically proven that far-infrared rays also have the functions of antibacterial and deodorizing.

The ceramic powder and metal powder contained in the plastic masterbatch in the present invention make the air generate negative ions under certain conditions. The effect of negative ions on human health: 1. The effect on the nervous system can strengthen the function of the cerebral cortex and mental activity, invigorate the spirit, improve work efficiency, and improve the weight of sleep. Negative ions can also strengthen the oxidation process of brain tissue, so that the brain tissue can get more oxygen. 2. The impact on the cardiovascular system. According to the observations of scholars, negative ions have the effect of significantly dilating blood vessels, which can relieve arterial vasospasm and achieve the purpose of lowering blood pressure. Condition recovery in patients with blood pressure and cardiovascular and cerebrovascular diseases. 3. The effect on the blood system. Studies have confirmed that negative ions can slow down the blood, prolong the coagulation time, increase the oxygen content in the blood, and facilitate the transportation, absorption and utilization of blood oxygen.
