Abstract
A method is provided for making a package having upper and lower foam cushion inserts which cooperate with each other to enclose an article therebetween which is placed in the package. The method includes the steps of forming convolutions in at least one surface of a piece of foam material to form a first foam insert, and then removing a section of convoluted foam material from the piece of foam material to form a cutout therein. Then, the removed section which forms the second foam insert is applied to one wall of a package with the unconvoluted surface thereof adhered to the wall, and the first foam insert is applied to an opposite wall of the package, with the second insert being in alignment with the cutout area of the first insert, whereby an article placed in the cutout area is cushioned between the foam material on the opposite walls of the package.
