ABSTRACT Apparatus and methods are disclosed for a high speed production line in which a container is wrapped with a plastic label comprising a foam polystyrene layer, there being means to move a leading edge of the label to the periphery of a rotating vacuum drum, means to apply ethylene chloride to the underside of the foam layer to form finite areas on the leading label edge and a finite area on the trailing edge. The finite areas have therein a rapidly solidifying tacky solution of the foam polymer in ethylene chloride, the tacky viscous solutions rapidly solidifying to form an adhesive bond. The solvent-applied label is quickly moved to a label wrapping station where it is wrapped around a container, the finite areas on the leading edge tacking the label to the container, and the finite area on the trailing edge forming a cohesive bond on the seam Ported by the overlapped label ends.
