A pad of a plurality of sheets of expandable slit paper is provided in which the paper expands in thickness when stretched to form expanded cells, wherein the sheets of expandable slit paper are bound together along a single edge and otherwise unbound together. In some embodiments, sheets of slit sheet material are removable for use of the slit sheet material for packing items or the like with the slit sheet material in an expanded state.

A self-inflating member is provided having a first flexible layer, a second flexible layer, a contracting element, a check valve and a first supporting element. The first and second flexible layers are connected to each other such that a cavity is formed there between. At least one of the first and second flexible layer comprises the check valve that creates a fluid connection between the cavity and the ambient environment. The contracting element is connected to the first and second flexible layers in at least a first and a second position, such that contraction of the contracting element moves the first and second position closer to each other. The first supporting element assists in supporting at least one of the first and second flexible layers, such that the cavity is expanded, which causes fluid from the ambient environment to flow through the check valve and into the expanded cavity.

The present disclosure relates to a system comprising at least one primary package accommodating at least one article, and a secondary package accommodating the primary package, wherein the secondary package comprises a second package material having a water vapor transmission rate lower than about 100 g/m.sup.2/day, as measured according to Water Vapor Transmission Rate Test, and a resistance to compression higher than about 150N.

A system for delivery of fragile payloads involves a structure having an approximately spherical aspect composed of rigid struts and flexible tendons joining ends of struts, the flexible tendons in tension placing the struts in compression, the structure having a hollow interior, and one or more fragile items wrapped in a shock-absorbing bio-degradable material such that no fragile item contacts another, forming a payload bundle, the payload bundle joined by fibrous filaments suspending the payload within the structure. The structure carrying the payload bundle is carried to a destination by an aerial vehicle and dropped from a height to the ground, where the structure rebounds and rolls, dissipating kinetic energy gained in falling, preventing the payload bundle from striking ground surface.

A fluid container has a first and second flexible membrane forming at least one chamber, a channel configured to receive pressurized inert gas, and one or more check valve assemblies disposed therebetween. The one or more check valve assemblies is formed from a continuous third flexible membrane folded at an apex, and configured to provide the flow of pressurized fluid in one direction upon inflation, from the channel to the at least one chamber, while restricting flow in the opposite direction. The one or more check valve assemblies are characterized in that they do not require pre-printing or electronic registering, thus allowing for an inflation flow rate of at least twice that of conventional inflatable packaging systems.
