Abstract
A plastic bag to be carried in the hand and a method for manufacturing the plastic bag are disclosed. The plastic bag comprises a top part, a jacket part and a bottom part. The top part is provided with a carrying aperture or the like and the bottom part is provided with a filling valve or the like by which the plastic bag can be filled with bulk material. The top part of the plastic bag is formed by a transverse seam and a reinforcing patch attached to one side of the upper end of the bag whereby the top part includes three material plies. A reinforcing patch can be attached to both sides of the upper end of the bag so that the top part is constituted by four plies. In the case where the plastic bag is intended for carrying larger quantities of bulk material, the top part of the plastic bag is formed by at least one fold formed at the upper end of the bag to define a fold portion and the reinforcing patch joins the folded top portion to the jacket part and at the same time overlies at least a part of the transverse seam, the top part thus including at least five thicknesses of material.
