Biodegradable polymer blends suitable for laminate coatings, wraps and
other packaging materials are manufactured from a blend of suitable
biodegradable polymers, such as 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.degree. C. "Soft" biopolymers tend to be more flexible and
pliable and typically have a glass transition temperature less than about
0.degree. 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.
