Packaging for microarrays

1. A packaging article comprising:

a plurality of connected outer pouches, each of the outer pouches made of an outer pouch material, and each of the outer pouches comprising one or more sealed outer pouch edges and one or more outer pouch open edges, wherein at least one of the one or more sealed edges is sealed with a seal that is shared between two adjacent sealed outer pouch edges, each outer pouch comprising an interior and an exterior; and

at least one inner pouch, each at least one inner pouch located substantially within an interior of at least one of the outer pouches and made of an inner pouch material, the inner pouch comprising:

at least one sealed inner pouch edge; and

at least one open inner pouch edge, wherein the open inner pouch edge is aligned with the open outer pouch edge;

wherein the outer pouch material comprises a film having oxygen and water barrier properties;

wherein at least one of the inner pouches contains a microarray device, the microarray device comprising:

a microneedle patch comprising a backing having a first major surface, a second major surface, and one or more microneedles protruding from the first major surface of the backing; and

a microneedle holder that holds the microneedle array backing.

2. The packaging article of claim 1 , wherein the inner pouch material comprises paper stock or card stock.

3. The packaging article of claim 1 , wherein no more than one inner pouch is contained within the interior any one of the connected outer pouches.

4. The packaging article of claim 1 , wherein a plurality of the connected outer pouches each comprise one of the at least one inner pouches within their interiors.

5. The packaging article of claim 1 , wherein at least one of the one or more sealed edges of the connected outer pouches comprises one or more indexing holes that do not communicate with the interior of any of the connected outer pouches.

6. The packaging article of claim 1 , wherein the at least one inner pouch comprises a feature selected from a notch, a slit, a hole, or a tab.

7. The packaging article of claim 1 , wherein the outer pouch material comprises at least one poly(ethylene)terephthalate layer.

8. The packaging article of claim 1 , wherein the outer pouch material comprises at least one metal foil layer.

9. The packaging article of claim 1 , wherein the outer pouch material comprises at least one polyethylene layer.

10. The packaging article of claim 1 , wherein the outer pouch material comprises at least one linear low density polyethylene layer.

11. The packaging article of claim 1 , wherein the microneedle array holder further comprises a handle for manipulating the microneedle array device.

12. The packaging article of claim 1 , wherein the microneedle array holder further comprises at least one feature selected from a ridge, a tab, a rail, and an embossment.

13. The packaging article of claim 6 , wherein the microneedle array holder further comprises a handle for manipulating the microneedle array device and at least one feature selected from a ridge, a tab, a rail, and an embossment, wherein the one or more features of the inner pouch interact with the handle of the microarray holder, the one or more features of the microarray holder, or both the handle and the one or more features of the microarray holder, to align the microarray holder with respect to the opening in the inner pouch and the opening in the outer pouch.

14. The packaging article of claim 13 , wherein the microarray holder is aligned such that the handle is oriented towards the opening in the inner pouch and the opening in the outer pouch.
