A corner post/edge protector structure comprises an apex portion, a pair of leg members disposed substantially perpendicular with respect to each other, and concave/convex transitional regions integrally interconnecting the leg members to opposite ends of the apex portion. The concave/convex transitional regions define axially extending strengthening ribs for enhancing the axial or columnar compressive strength characteristics of the structure when the same is used in conjunction with stacks or tiers of packages, containers, or palletized loads. In addition, the transitional regions permit outer and inner surface portions of the leg members to be coplanar with outer and inner surface portions of the apex portion so as to facilitate or enable compact storage of the containers, packages, or palletized loads within cargo holds and storage facilities. Still further, the transitional regions enable the leg members to undergo resilient flexural movements under impressed packaging strapping loads or forces and facilitate favorable distribution of the strapping loads or forces.

An inflatable dunnage bag is comprised of a first and independently sealed bag that is inserted within a paper tube before the tube ends are sealed to form a second, independent bag. The combination of an inner bag within an outer bag provides increased bursting strength compared to similar ply bags created as only a single bag. The combination bag is much easier to construct since at least two plies of paper that are pressed to form the inner bag are no longer part of the bag end folding and sealing process. This is especially true if the outer bags ends are sealed by stitching them together.

A cargo airbag structure system for use within a cargo bay of a transport vehicle in order to buffer and stabilize loads, such as, for example, large paper rolls or drums, comprises two inflatable bladders disposed in an overlapping disposition with respect to each other within a sealed, expandible, multi-ply paper container. When interposed between the cargo load rolls, the airbag structure conforms to the external contours of the cargo load rolls which serves to not only enable the airbag system to buffer and stabilize the cargo loads, but in addition, the airbag system is stably retained between the cargo load rolls. In order to prevent friction, abrasion, or pinching of the bladders during the inflation process as well as during use of the airbag system when the bladders are disposed in their inflated state, the inflatable bladders are disposed within encasing sleeves which fully envelop the bladders along the longitudinal extents thereof, the opposite ends of the sleeves being open. By preventing the noted friction, abrasion, and pinching of the bladders, the structural integrity of the bladders is preserved resulting in enhanced service life.

Dual bladder airbag

An airbag for use in a cargo bay of a transport vehicle for buffering and stabilizing a load, usually large paper rolls or drums, is provided with two inflatable, gas-tight bladders surrounded by a multi-ply paper container. The bladders are situated in an overlapping relationship with respect to each other. This enables the load to be buffered and stabilized while minimizing the need for additional materials.
