a main seal that extends through portions of the one or more first layers of film and also through portions of one or more additional layers of film of the container; and

a first reinforcing seal that extends through portions of the one or more first layers of film but not through any portion of the one or more additional layers of film;

wherein at least a portion of the first reinforcing seal is disposed between at least a portion of the main seal and at least a portion of the first expanded structural support volume.

2. The container of claim 1 , wherein at least a portion of the first reinforcing seal is immediately adjacent to at least a portion of the main seal.

3. The container of claim 1 , wherein at least a portion of the first reinforcing seal is immediately adjacent to at least a portion of the first expanded structural support volume.

4. The container of claim 1 , wherein the main seal is a fin seal.

5. The container of claim 1 , wherein the main seal is an outwardly projecting fin seal.

6. The container of claim 1 , wherein at least a portion of the main seal is disposed along a line that separates a front of the container from a back of the container.

7. The container of claim 1 , wherein, at a particular location along the main seal, the main seal is effectively angled, with respect to the reinforcing seal, and at least a portion of the first reinforcing seal is disposed adjacent to the particular location.

8. The container of claim 7 , the first reinforcing seal is only disposed proximate to the particular location.

9. The container of claim 7 , wherein the main seal is effectively angled with an effective obtuse angle, and at least a portion of an outer edge of the first reinforcing seal is substantially linear.

10. The container of claim 7 , wherein the main seal is effectively angled with an effective obtuse angle, and substantially all of an outer edge of the first reinforcing seal is substantially linear.

11. The container of claim 10 , wherein the first reinforcing seal has an overall shape that is substantially triangular.

12. The container of claim 7 , wherein the main seal is effectively angled with an effective acute angle, and at least a portion of an outer edge of the first reinforcing seal is substantially curved with a curve that is concave with respect to the first expanded structural support volume.

13. The container of claim 8 , wherein the main seal is effectively angled with an effective acute angle, and substantially all of an outer edge of the first reinforcing seal is substantially curved with a curve that is concave with respect to the first expanded structural support volume.

14. The container of claim 13 , wherein the first reinforcing seal has an overall shape that is substantially like a boomerang.

15. The container of claim 1 , wherein:

the main seal extends through portions of two first layers of film and also through portions of two additional layers of film of the container; and

the first reinforcing seal extends through portions of the two first layers of film but not through any portion of the two additional layers of film.

16. The container of claim 1 , wherein:

the first reinforcing seal is disposed on one side of the main seal;

the container includes a second expanded structural support volume made from one or more second layers of film, and disposed on another side of the main seal;

the main seal extends through portions of the one or more second layers of film; and

the container includes a second reinforcing seal that extends through portions of the one or more second layers of film but not through any portion of the one or more first layers of film;

wherein at least a portion of the second reinforcing seal is disposed between at least a portion of the main seal and at least a portion of the second expanded structural support volume.

17. The container of claim 16 , wherein at least a portion of the second reinforcing seal is immediately adjacent to at least a portion of the main seal and immediately adjacent to at least a portion of the second expanded structural support volume.

18. The container of claim 16 , wherein substantially all of the first reinforcing seal is directly opposite from at least a portion of the second reinforcing seal.

19. The container of claim 16 , wherein substantially all of the first reinforcing seal is directly opposite from substantially all of the second reinforcing seal.

20. The container of claim 16 , wherein:

the container includes a structural support frame that supports the product volume; and

the structural support frame includes the first expanded structural support volume and the second expanded structural support volume.
