IN-MOLD LABELING SYSTEMS WITH POLYMERIC LABEL RECEPTOR AND IN-MOLD LABELING METHODS THEREWITH

摘要

An in-mold labeling system includes a molding apparatus having a first mold half and a second mold half that opposes the first mold half, the mold halves defining at least one mold cavity contained within a cavity wall. The in-mold labeling system further comprises a polymeric label receptor fixed to at least a portion of the cavity wall of the at least one mold cavity. The polymeric label receptor has a tacky contact face facing the inside of the at least one mold cavity when the molding apparatus is in the closed position. During a molding process, the tacky contact face of the polymeric label receptor receives a mold-side face of a label. The label is held in position against the tacky contact face during the molding process by surface tension between the mold-side face of the label and the tacky contact face of the polymeric label receptor.
