Claim:
A two-sided direct thermal adhesive label adapted for forming a pouch which (i) is defined between the label and a package to be mailed after the label is affixed to the package, (ii) has a pouch opening through which a separate item can be inserted into the pouch to be mailed along with the package, and (iii) is sealable to close the pouch opening after a separate item has been inserted through the opening and placed in the pouch, the label comprising: a first substrate having an outer face which is at least partially coated with a thermally sensitive material and an inner face which is at least partially coated with an adhesive, wherein the first substrate has disposed therein one or more perforation lines forming (i) a substantially rectangular-shaped central portion of the first substrate, and (ii) a substantially O-shaped peripheral portion of the first substrate; and a second substrate having an outer face which is at least partially coated with a thermally sensitive material and an inner face which is at least partially coated with a release material, wherein the second substrate has disposed therein one or more die cuts forming (i) a substantially rectangular-shaped central portion of the second substrate which is substantially congruent to the rectangular-shaped central portion of the first substrate, (ii) a substantially U-shaped peripheral portion of the second substrate which is substantially aligned with a first portion of the O-shaped peripheral portion of the first substrate, and (iii) a substantially I-shaped end portion of the second substrate which is substantially aligned with a second portion of the O-shaped peripheral portion of the first substrate.
