Abstract

A packaging device is provided for an item of three-dimensional shape comprising a non-porous deformable outer wrap characterized in being deformable in three dimensions to at least partially surround the item of three-dimensional shape therein. The device includes a mass of loose fill elements disposed within the outer wrap and can occupy a first volume in a first storage state sufficient to permit the packaging device to be stored. The device further provides that the mass of elements disposed within the outer wrap can occupy a second volume in a second use state to shape about the item of three dimensional shape and to permit the elements to deform within the outer wrap to accommodate the three-dimensional shape of the item. The outer wrap and the elements disposed within the outer wrap are biodegradable. The elements are adapted to change from the first storage state of unpopped corn kernels to the second use state of popped popcorn kernels.
