Patent ID: 8003184

Claim:
A card sheet comprising: a top material having a plurality of weakened separation lines defining a plurality of attached cards; a stretchable carrier material of at least one layer of polymer; the top material having an outer printable surface; at least one of the weakened separation lines defining at least a portion of a border of at least one of the attached cards; the stretchable carrier material being directly attached to an inner surface of the top material; and the card sheet being constructed so as to allow at least one of the attached cards to be separated from the stretchable carrier material at an interface between the top material and the stretchable carrier material to form a separate or separable card after a printing operation on the printable surface; wherein the stretchable carrier material is sufficiently stretchable so as to at least partially release at least one of the attached cards therefrom in response to stretching of the stretchable carrier material.
