<p>A method and apparatus for forming a package (10) for a three dimensional block (11) wherein the package (10) is formed of flexible film doubled along one edge with end seals (13,14) joining the ends of the film and a reclosable zipper (15) along the other remaining edge with the zipper (15) being longer than the length (2-1) of the block and longer than the space (2-2) between the end seals (13,14) so that as the zipper (15) is opened, a mouth is formed sufficiently large to allow for insertion or removal of the block (11) through the mouth of the package (10). <IMAGE></p> |
