1. A method for applying an expanded content label in an in-mold labeling process, comprising the steps of: placing an expanded content label including a base and an overlaminate, each having different heat deformation properties, a multi-sheet information unit and a heat-activated adhesive in a mold with the adhesive facing away from the mold; molding an article within the mold so that the heat-sensitive adhesive is activated causing the expanded content label to be adhered to the article; and removing the molded article with the adhered expanded content label from the mold. 2. The method of claim 1 wherein said step of molding comprises blow molding. 3. The method of claim 1 wherein a plurality of layers cooperate together to enclose the multi-sheet information unit within the expanded content label. 4. The method of claim 3 further comprising the step of simultaneously activating the base and the overlaminate such that the expanded content label properly conforms to the surface of the article as the article is molded. 5. The method of applying an expanded content label in an in-mold labeling process comprising the steps of: providing an expanded content label having a booklet, a heat sensitive adhesive, a base and a cover, the base and the cover having different heat deformation properties; intermittently and individually transferring said expanded content label to the interior of a mold such that said heat sensitive adhesive faces the interior of the mold; and molding an article within said mold whereby the label in the interior of the mold adheres to the article upon activation of the heat-sensitive adhesive on the label. 6. The method of claim 5 wherein said step of molding comprises blow molding. 7. The method of claim 6 wherein said base layer includes a first surface, said heat sensitive adhesive disposed on said first surface. 8. The method of claim 7 wherein said base layer includes a second surface, said overlaminate layer releasably adhered to a portion of said second surface. 9. The method of claim 8 wherein said booklet is sandwiched between said second surface and said overlaminate layer. 10. An in-mold labeling process comprising the steps of: positioning an expanded content label including a booklet, a base substrate and an overlaminate, the base substrate and overlaminate having different heat deformation properties, and a heat-sensitive adhesive in a mold; and molding a thermoplastic article in the mold whereby the heat-sensitive adhesive is activated and secures the expanded content label to the article. 11. The in-mold labeling process of claim 10 comprising the step of repeating said positioning and molding steps. 12. The in-mold labeling process of claim 11 wherein the booklet is sandwiched between the base substrate and the overlaminate.
