Provided is a compaction package that includes a flexible film portion and a heat shrink film portion coupled to part of the flexible film portion. The compaction package has a bottom, a sidewall, and an open top that together define a hollow interior space adapted to receive and contain a granular material. In a first configuration prior to exposure to a heat source sufficient to raise the temperature of the compaction package to a certain critical heat shrink temperature, the interior space of the compaction package has a first volume. In a second configuration after exposure to the heat source, the interior space of the compaction package has a second volume that is less than the first volume.
