Abstract: The composite bag of the present invention generally comprises a multi-layered, inner laminated woven bag for bulk packaging of food products, particularly rice and grain products. The composite bag of the present invention generally comprises a top outer layer made of a polymer film and further comprising an anti-skid coating on one surface and reverse printed matter on its opposing surface; a middle layer comprising a polymer woven layer; a base inner-barrier layer comprising a polymer film that forms the interior liner of the composite bag; and a plurality of holes formed by the top outer layer, the middle layer, and the base inner-barrier layer. The layers of the present invention can be adhesively laminated to each other.

Abstract: Provided are a packaging bag in which the breakage of a handle or irritation to a user's hand due to a load of the packaging bag when the user moves while gripping the handle in a state in which heavy contents such as grain or the like fills the packaging bag can be minimized by forming a sealed handle at the packaging bag, and a method of manufacturing the same. The packaging bag includes a packaging sheet constituted by a first sheet, and second sheets extending from both sides of the first sheet to be folded in a rear-surface direction of the first sheet so that both ends overlap to be sealed; a reinforcement film inserted and fixed between the first sheet and the second sheets; an upper sealing section sealed so that inner surfaces of the reinforcement film and the packaging sheet adhere to seal an upper section; and a handle section positioned at the upper sealing section and punched to be gripped.
