Biodegradable polymer blends suitable for laminate coatings, wraps and other packaging materials are manufactured from at least one "hard" biopolymer and at least one "soft" biopolymer. "Hard" biopolymers tend to be more brittle and rigid and typically have a glass transition temperature greater than about 10° C. "Soft" biopolymers tend to be more flexible and pliable and typically have a glass transition temperature less than about 0° C. While hard and soft polymers each possess certain intrinsic benefits, certain blends of hard and soft polymers have been discovered which possess synergistic properties superior to those of either hard or soft polymers by themselves. Biodegradable polymers include polyesters, polyesteramides, polyesterurethanes, thermoplastic starch, and other natural polymers. The polymer blends may optionally include an inorganic filler. Films and sheets made from the polymer blends may be textured so as to increase the bulk hand feel. Wraps will typically be manufactured to have good "dead-fold" properties so as to remain in a wrapped position and not spring back to an "unwrapped" form.

The invention modulates the air volume in foam cores of cushioning support devices and any other support apparatus using foam or similar materials. The foam core can be incrementally modulated to realize an infinite number of comfort levels as to softness and support firmness. The core consists of self-inflating open-cell flexible polyurethane foam and is completely sealed within an enclosure fitted over it, with one or more valves installed in the side walls which communicate with the outside air. Through the valves air is selectively withdrawn from the foam core, allowing the foam's density to increase. The invention uses relatively inexpensive foam, but through air volume modulation achieves a tactile feel of supreme softness for the user, without giving up the necessary firmness to support the body, as happens with very soft foam (bottoming-out or hammock-effect). When air is extracted from a self-inflating foam core, the surface of the core will soften uniformly while maintaining its support firmness. Contrary to this, when pressure is exerted on, for example, traditional coil spring core mattresses, their surface will harden. Integral part of the invention is a device using balanced springs in valve assemblies to avoid compression set, an irreversibly solid state of totally air-depleted foam.
