Abstract

The present invention relates to a grain sack having a UV-blocking function, the sack storing grain therein through an upper open portion, and including: an inner layer formed by interlacing strips made of a synthetic resin so as to have a lattice structure; a reinforcing layer provided on an outer surface of the inner layer; a film layer provided on an outer surface of the reinforcing layer and having a UV-blocking function; and an antimicrobial layer coated on at least a portion of an inner surface of the inner layer, wherein the synthetic resin includes polyethylene or polypropylene, and multiple micro-ventilation holes are formed to pass through the inner layer, the reinforcing layer, and the antimicrobial layer, thereby enabling air circulation in the sack.
