Patent ID: 7546721

Claim:
A method of making tetrahedron packages from a substrate with a foil layer, the package having substantially uniform tear zones comprising: forming a tube from a sheet material including a first image printed at a first location and a second image printed at a second location along a sheet of material having a foil layer, such that the first image is oriented about 180° from the second image, and such that the first image and the second image are longitudinally aligned along the sheet material and adjacent to one another; forming a first tetrahedron package including the first image and a second tetrahedron package including the second image from the tube, such that the first tetrahedron package and the second tetrahedron package are connected by a seal zone; and forming substantially uniform tear zones in the first tetrahedron package and the second tetrahedron package, wherein the substantially uniform tear zones are at the substantially same location with respect to an edge of the first tetrahedron package and an edge of the second tetrahedron package.
