A flexible package that conforms closely to and fully encloses one or more objects with square or rectangular sides is formed of a flexible, light weight, and preferably heat sealable material such as a thermoplastic. In the preferred embodiments, the packaging is manufactured from tubular or parallel sheets of flexible thermoplastic material laid flat to form two layers, which are than folded into a U-shape with the band at the bottom and the side seams heat sealed to form an open topped, double walled package. The package specifications are determined from the dimensions and quantity of the objects to be packaged. Prior to sealing the sides of the package, the bottom portion of the material is tucked up between the sides to a distance equal to one-half the depth of the finished container so that when the objects are placed in the container, the bottom corners spread to form right angles. At a distance up from the bottom equal to the height of the finished package, internal sealing flaps are formed by cutting areas in the upper portion of the package inwardly for a distance equal to one-half the depth of the objects to be contained and upwardly for a distance equal to one-half the depth, plus an overlap. These fold over the contained objects to create a top with corners at right angles, without excess material at the sides. The flaps are sealed by means such as a strip of adhesive or double sided tape.

A flexible package for containing rectangular or square sided objects in a closely conforming relationship comprising: a double layer of flexible material formed in a “U”shape with one layer forming an inner wall and the other layer forming an outer wall, wherein the bottom of the “U”is tucked up between the two sides of the “U”to a distance equal to one half the desired depth of the finished package and the edges of the sides of the “U”are secured together, including the edges of the tucked up portion, to form a package open at its top end only, said edge sealed tucked in portion, when expanded to surround the objects held in the package, forming a generally flat, rectilinear bottom portion, integral upper portions of said inner wall extending beyond the upper ends of the combined height of the objects to be contained to form sealing flaps that can be folded across the top portion of the finished package to enclose the top end of the package in said closely conforming relationship when it is fully loaded with the objects, and integral upper portions of said outer wall extending beyond the upper ends of said combined objects to form handles.
