Abstract: The invention is a method of overlaying a plastic film material on a shipping container blank whereby all surfaces and edges are sealed. A container subsequently made from the blank is rendered highly water resistant. The film material is applied to both sides of the blank and severed from the supply source. The covered blank is then heated above the softening point of the film. The film becomes bonded to the surfaces of the blank and sags around the edges and into any openings so that the film on the two sides of the blank come into contact and are sealed to each other. The edges and any slits and cutouts are then trimmed, as by a die cutter, while preserving the seals along the edges. Containers made by the process can generally be recycled, in contrast to wax or resin impregnated corrugated board.

Abstract: In accordance with the present invention, products are contained within a continuous cylindrical sleeve in a low- or no-tension condition. Products are captured within the sleeve during its formation. The sleeve forms a continuous path encircling the product(s) in at least one plane through the products and package, defining an axial direction normal to the plane and a circumferential direction around the product(s) within the plane. One or more axially-extending pleats are unitarily formed from the material comprising the cylindrical wall of the sleeve, such that the circumference of the cylindrical sleeve is reduced. By reducing the circumference of the cylinder the interior volume of the sleeve, and thus the finished package, is reduced, thus subjecting the products within the package to a compressive force. The compressive force is imparted by a uniform reduction in circumference resulting in a uniform inwardly-directed product compression.
