11. The method of claim 1 , wherein:
the bonding of the first plurality of sections of the second web to the first web is comprised of bonding the first plurality of sections of the second web to the first web with adhesive material; and
the bonding of the second plurality of sections of the second web to the second web is comprised of bonding the second plurality of sections of the second web to the second web with adhesive material.
12. The method of claim 1 , wherein the separating comprises delaminating the first and second laminates from one another.
13. The method of claim 1 , wherein at least one of the first and third webs comprises paper.
14. The method of claim 1 , wherein the microwave energy interactive material is metallic.
15. The method of claim 1 , wherein the microwave energy interactive material comprises foil.
16. The method of claim 1 , wherein:
an initial laminate comprises the first and second webs;
the forming comprises laminating the initial laminate and the third web to one another; and
the applying of the release material is comprised of applying the release material to the initial laminate prior to the laminating of the initial laminate and the third web to one another.
17. The method of claim 16 , wherein:
the first plurality of sections of the second web comprises opposite first and second sides;
the bonding of the first plurality of sections of the second web to the first web is comprised of bonding the first sides of the first plurality of sections of the second web to the first web; and
the applying of the release material is comprised of applying the release material to the second sides of the first plurality of sections of the second web.
18. The method of claim 1 , further comprising laminating a fourth web to the second laminate, so that the second plurality of sections are positioned between the third and fourth webs.
19. The method of claim 18 , wherein:
the third web comprises paper, and
the fourth web comprises a polymer film.
