1. A protective packaging device comprising:
a first ply having a plurality of extended portions, each of the plurality of extended portions including a base perimeter enclosing an open base region and an extended surface protruding in one direction from a plane defined by the first ply in a generally flat state, the extended surface having a larger surface area than the open base region; and
a second ply sealed to the first ply around at least a portion of the base perimeter of the open base region of each of the plurality of extended portions, forming sub-chambers on a side of the first ply opposite the protruding direction, wherein each of the first ply and the second ply remain unsealed across the open base region defining regions within the sub-chambers suitable to contain a fluid volume therein,
wherein the sub-chambers are interconnected via one or more intra-chamber channels, allowing each of the sub-chambers to receive and release fluid in response to external pressures.
