The present invention relates to an assembly type agricultural and marine product packing box for maintaining watertightness, and more specifically, to an assembly type agricultural and marine product packing box for maintaining watertightness, which is formed by coating a coating member formed in a triple structure on an inner plane or the inner plane or an outer plane integrally to a body after forming the body by foaming or chemical crosslinking of polypropylene (PP) and high density polyethylene (HDPE) in an unfolded state, and occupies a small storage and transportation area in the unfolded state during transportation and storage, and is assembled like a box by inter-combining during usage, and can pack various agricultural and marine products like marine products, agricultural products and fruits by maintaining watertightness more safely. In the packing box where a front (30), a rear (40), a left side (50) and a right side (60) are formed at both sides of a bottom floor (20) and a cover plane (70) is connected to the rear (40), an inside or the inside and an outside of a body (80) forming the front (20), the rear (30), the left and right side (60) and the cover plane (70) is surrounded by a coating member (100) comprising three layers of an outer layer (110), a core layer (120) and an inner layer (130) and then is heated to the temperature of 95-120°C so that the body (80) and the coating member (100) are coated in a body, and a folding prevention protruded part (90) is formed on the left and right side (50, 60) of the front (30) and the left and right side (50, 60) of the rear (40) to maintain watertightness for packing. |
