ABSTRACT:
A method of making tetrahedron packages having substantially uniform tear zones is disclosed. The method includes printing a first image at a first location of a sheet material and a second image at a second location of the sheet material, such that the first image is oriented 180° from and longitudinally arranged with respect to the second image. A tube is formed from the sheet material. The tube runs through a package forming machine to form a first tetrahedron package including the first image and a second tetrahedron package including the second image from the tube. The first tetrahedron package and the second tetrahedron package are connected by a seal zone. Substantially uniform tear zones are formed in the seal zone using a laser or a knife. The substantially uniform tear zones are at the same location with respect to a side edge of the first and second tetrahedron packages.
