ABSTRACT:
A synthetic resin bag is used for storing grain or animal feed. The bag includes an inner layer made of polypropylene textile woven in gauze, a coating layer attached to an inside surface of the inner layer, and an outer layer attached to an outside surface of the inner layer. Attaching between the layers is made by polypropylene resin applied thereto. The coating layer is made of high-density polyethylene film, and the outer layer is made of oriented polypropylene film mixed with non-slip material for raising coefficient of friction of the outer layer to 0.5 or more. Also, the outer layer has a printed inside layer. The bag allows inhibiting penetration of moisture in the air and preventing absorption or leakage of fat or oil in contents. Also, the bag is prevented from slipping and falling when stacked or conveyed.
