Claim 0:
1. A packaging system for storing a bioprosthetic device, the packaging system comprising:
a package defining an internal volume when the package is sealed;
at least one bioprosthetic device; and
at least one humidity control device comprising
an at least partially gas-permeable enclosure, and
a humidity control solution disposed within the at least partially gas-permeable enclosure, wherein the humidity control solution has a total weight;

wherein the at least one bioprosthetic device and the at least one humidity control device are configured to be contained within the internal volume of the package when the package is sealed;
wherein a ratio of the total weight of the humidity control solution to the internal volume of the package when the package is sealed is at least about 6 mg/mL;
wherein the humidity control solution is configured to maintain a relative humidity within the internal volume of the package within about ±5% of a target relative humidity across a temperature range from about −18° C. to about 45° C., by selectively liberating and absorbing water vapor through the at least partially gas-permeable enclosure; and
wherein the target relative humidity is selected from the range from about 15% to about 95%.
