A blow molded plastic container (10) disclosed includes at least one plastic label (L) on a side wall (12) which has abruptly curved portions (42,44,46) that provide a generally continuous outer surface at the junctions of the label edges with the side wall. The plastic label (L) may have different constructions for resisting the transmission of fluids through the container side wall and for providing a heat activated bond that secures the label to the container side wall during the blow molding process. Different preferred plastics utilized to provide the barrier include polyvinylidene cloride, polypropylene, polyethylene, ethyl vinyl alcohol, acrylonitrile, and polyethylene terephthalate which may be used singly or with multiple types either dispersed within each other or in separate layers. The heat sensitive adhesive may be applied as a coating to the inner surface of the plastic label, dispersed within the plastic of the label, or provided by the inner surface of the label plastic that also functions as the barrier. Best results are achieved when a pair of the labels (L) are provided on oppositely facing sides of the container side wall (12) so as to more fully cover the container and thus increase the resistance to the transmission of fluids.

A container comprising: a plastic side wall; a plastic label of uniform thickness having an outer surface that faces outwardly and an inner surface that faces inwardly toward the side wall; said label extending partially around the side wall and having side edges spaced from each other as well as upper and lower edges that extend between the side edges thereof; said side wall having abruptly curved portions adjacent the edges of the label to provide smooth junctions between the container side wall and the outer surface of the label at the label edges; said label being made of a plastic that provides a barrier resistant to transmission of fluids; and a heat sensitive adhesive that secures the inner surface of the label to the side wall.
