Abstract
In ordinary temperature some ceramic materials can absorb the environmental energy and radiate appropriate amount of far infrared ray with wavelength of 4 μm˜14 μm. Far infrared ray with wavelength of 4 μm˜14 μm 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 μm-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.
Claims7
A flexible film product comprising a flexible film base having a thickness of between 4 μm˜200 μm coated with a thin coating of a ceramic material which absorbs environmental energy and radiates far infrared radiation of wavelength 4˜14 μm, wherein said far infrared ceramic material is selected from the group consisting of Al2O3, Fe2O3, TiO2, Cr2O3, SiO2, Y2O3, MgO, ZrO2and mixtures thereof and wherein the thickness of the coating of ceramic material is between 1 μm ˜50 μm, and said ceramic material of said coating is dispersed in a bonding agent;
- with the proviso that the thickness of said coating is less than the thickness of said film base.
