Cassette bags for transporting biomaterials
An envelope is configured to hold, support, and protect an article such as a blood bag during transportation under fic temperatures. The envelope includes a single piece component (e.g., a monolithic component), including multiple panels that are configured to fold to form an enclosure that surrounds the article such as the blood bag for support and protection of the article such as the blood bag.

4. The envelope of claim 1 , wherein the first sealing mechanism is configured to couple the front panel to the back panel after the sealing apparatus is closed.
5. The envelope of claim 4 , wherein the second sealing mechanism is configured to couple to an external surface of the back panel.
6. The envelope of claim 5 , wherein a portion of the front panel forms a crease along a top edge of the envelope in response to coupling the second sealing mechanism to the back panel.
7. The envelope of claim 1 , wherein the first plurality of layers and the second plurality of layers each comprise:
an external layer comprising a polymeric material;
an internal layer comprising an absorbent material; and
a barrier layer disposed between the external layer and the internal layer.
8. The envelope of claim 7 , wherein the first plurality of layers and the second plurality of layers each comprise a first tie layer disposed between the external layer and the barrier layer.
9. The envelope of claim of claim 7 , wherein the first plurality of layers and the second plurality of layers each comprise a sealant layer, the sealant layer at least partially defining the first seal.
10. An envelope for transporting an object, the envelope comprising:
a front panel and a back panel each comprising:
an internal layer defining an internal surface, the internal surface at least partially defining a cavity of the envelope;
an external layer disposed outward from the internal layer;
a barrier layer disposed between the internal layer and the external layer;
a sealant layer disposed between the barrier layer and the internal layer;
a first tie layer disposed between the external layer and the barrier layer; and
a second tie layer disposed between the sealant layer.
11. The envelope of claim 10 , wherein a first portion of the sealant layer of the front panel is bonded to a second portion of the sealant layer of the back panel to form a first seal.
12. The envelope of claim 11 , further comprising a sealing apparatus disposed between the front panel and the back panel, the sealing apparatus configured to transition from an open state to a closed state, the sealing apparatus and the first seal defining a cavity of the envelope in response to being in the closed state.
13. The envelope of claim 10 , wherein the first tie layer couples the external layer to the barrier layer.
14. The envelope of claim 13 , wherein the second tie layer couples the sealant layer to the barrier layer.
15. The envelope of claim 14 , wherein the sealant layer is configured to protect the barrier layer.
16. A method of shipping a biomaterial article, the method comprising:
disposing the biomaterial article in an envelope, the envelope comprising an internal layer, an external layer, a barrier layer disposed between the internal layer and the external layer, and a sealant layer disposed between the internal layer and the barrier layer;
transitioning a sealing apparatus from an open state to a closed state to create a first seal of a cavity defined by the sealing apparatus and a manufacturing seal;
coupling a first internal surface of a front panel of the envelope to a first internal surface of a back panel of the envelope via a first sealing mechanism to create a second seal; and
coupling the first internal surface of the front panel of the envelope to an external surface of the back panel of the envelope to create a third seal.
17. The method of claim 16 , wherein a crease is formed at a top edge of the envelope in response to coupling the first internal surface to the external surface.
18. The method of claim 16 , further comprising placing the envelope in a carrying bag.
19. The method of claim 18 , further comprising placing a plurality of the envelope in the carrying bag, each envelope in the plurality of the envelope having a respective biomaterial article disposed therein.
20. The method of claim 19 , further comprising transporting the carrying bag.
21. An envelope for transporting an object, the envelope comprising:
an internal layer defining an internal surface, the internal surface at least partially defining a cavity of the envelope;
an external layer disposed outward from the internal layer;
a barrier layer disposed between the internal layer and the external layer;
a sealant layer disposed between the barrier layer and the internal layer;
a first tie layer disposed between the external layer and the barrier layer; and
a second tie layer disposed between the sealant layer.
22. The envelope of claim 21 , further comprising a sealing system including a plurality of sealing apparatuses.
23. The envelope of claim 21 , wherein the external layer comprises a polymeric material, and wherein the internal layer comprises a desiccant layer.
24. The envelope of claim 23 , wherein the first tie layer and the second tie layer comprise an adhesive resin.
25. The envelope of claim 24 , wherein the barrier layer comprises a second polymeric material different from the external layer, and wherein the sealant layer comprises a third polymeric material different from the barrier layer and the external layer.
26. The envelope of claim 21 , wherein the envelope is configured to be resistant to brittleness and shattering at cryogenic temperatures.
