The present invention relates to a functional grain sack where natural minerals are added. The present invention replaces an existing grain sack used simply to protect grains for adding natural minerals of red clay, jade powder, and biotite powder since the far infrared ray emitting material having excellent freshness retaining effect, excellent antimicrobial effect, excellent deodorizing effect, and excellent moisture removal effect to dak-pulp (paper mulberry bast fiber pulp) having high viscosity and excellent solidity as a pulp material to be mixed and make paper. As such, the present invention is capable of freshly storing grains such as rice and mixed grains as antimicrobial effect, deodorizing effect, and moisture removal effect due to emissions of far infrared rays for a long period of time; and freshly storing the grain from a distribution step to the storage step. |
