Protective film product capable of radiating far infrared ray with wavelength of 4 mu m~14 mu m

摘要

In ordinary temperature some ceramic materials can absorb the environmental energy and radiate appropriate amount of far infrared ray with wavelength of 4 &mgr;m m˜14 &mgr;m. Far infrared ray with wavelength of 4 &mgr;m˜14 &mgr;m can be absorbed by cell molecules of the living beings to cause resonance and activation. By utilizing this property, the slurry of the far infrared ceramic materials is coated with &mgr;m-grade thickness on some flexible base films to form the product of the present invention, and is used as as a wrappage, a protective lining, . . . etc., so as to achieve the freshkeeping for the food, the late-ripen for the picked fruits, as well as the warmkeeping, raising and healthkeeping for the living beings.
