Abstract
Abstract A method for forming a package containing a quantity of lading wherein the container for the lading is formed from two blanks made of rigid foldable material, each including an end wall and alternate side wall forming panels, one being unflanged and one including peripheral flanges along each longitudinal edge. The method includes the steps of: forming one of the blanks into a generally U-shape while concurrently partially surrounding the lading, forming the second blank into a generally U-shape concurrently partially surrounding the first blank and its lading with the end wall forming panels in opposed facing relation, and securing each alternate side wall forming panel of the unflanged blank to the peripheral flanges along one longitudinal edge of the flanged blank to form the package. The blanks are not attached together during the folding operations.
