ABSTRACT A paper bag having a barrier material and a method of coating paper for use in making such a paper bag. The inventive method comprises of the steps of: continuously removing in a direction of travel a strip of paper from a source of paper at a predetermined speed; masking with a liquid impervious mask at least one longitudinal portion of the strip of paper in the direction of travel; routing the strip of paper and the mask through a bath of liquid barrier material, the liquid barrier material substantially saturating the strip of paper except for the masked portion; removing the bask from the strip of paper after moving it out of the liquid barrier material, and forming a selected length of the strip of paper into the bag. The paper bag has at least a front side and a back side each having at least one longitudinal portion extending the length of the bag. The longitudinal portion has a width less than the width of the front and back sides. A barrier coating on the front and back sides of the bag is provided except on an area of the longitudinal portions of the front and back sides.
