A cushioning sheet includes a first layer defining a first inner surface; a second layer coupled to the first layer, the second layer defining a second inner surface facing the first inner surface so that the first inner surface and the second inner surface define a plurality of voids therebetween; and a plurality of cushioning inserts disposed between the first layer and the second layer, wherein each of the plurality of cushioning inserts is received in a corresponding one of the voids, and each void has a diameter that is larger than a diameter of the cushioning insert disposed therein so that each void is configured to loosely receive the cushioning insert disposed therein.

A bubble A-B liner insulation package includes a box defining a box cavity, an A-liner configured to be positioned in the box cavity, the A-liner constructed from a first panel of liner material defining three A-liner portions, and a B-liner configured to be positioned in the box cavity adjacent to the A-liner, the B-liner constructed from a second panel of liner material defining three B-liner portions. The liner material comprises at least a first bubble layer formed from a thermoplastic film, an upper layer joined to an upper side of the bubble layer, and a lower layer joined to a lower side of the bubble layer, wherein at least one of the thermoplastic film, the upper layer, and the lower layer is at least partially comprised of metallized high density polyethylene (MHDPE).

A cushioning sheet comprising a base layer defining a plurality of voids and a plurality of cushioning inserts, wherein each cushioning insert is received in a corresponding void and the base layer is covered with a material coating configured to limit the passage of air therethrough.
