Disclosed is a process for the preparation of a labelled hollow vessel, which comprises blow-forming a single-layer or multiple-layer plastic parison or sheet in a blow mold having a label attached to the inner surface of a cavity thereof to bond the label to the surface of a side wall portion, wherein a label composed mainly of a drawn film of a plastic material having a heat shrinkage factor larger than the forming shrinkage factor of a plastic material constituting the outer surface of the vessel at a temperature (T1) lower by 40°C than the melting point or softening point of the plastic material constituting the outer surface of the vessel is used as the label. The labelled vessel prepared according to this process has no bulge or wrinkle on the outer surface of the attached label and excellent in the adhesion, peeling resistance and heat resistance of the label.
