Abstract: A container that is a spirally-wound, laminated, and cylindrically shaped is capable of protecting a mortar or other round from a large number of environmental conditions. The laminate material includes a layer of low-density polyethylene (LDPE) heat-bonded to a kraft paper, and is both durable, strong, and moisture-resistant. During the container manufacturing process, multiple layers of the laminate material, augmented by one or more layers of aluminum foil, are wound in a spiral fashion over an interior cylinder of ammunition container board, using conventional tooling and machinery. Layers of the cylinder are bonded to their contiguous neighbors by adhesive. The ends of the containers are sealed with crimped metal end caps, effecting a durable and moisture-resistance seal and giving the cylinder added crush-resistance. The construction of the container requires no high temperature operations, produces no noxious fumes, and does not expose workers to hazardous or toxic materials.
