A blow molded polyethylene terephthalate container (20) is disclosed as having a noncylindrical wall (28) to which at least one label (38) is secured with a textured surface provided by an in-mold labeling operation that prevents label shifting during the blow molding operation. The textured label surface includes isolated depressions (53) that are defined by mold projections (72) which define mold passages (74) through which a vacuum is drawn to provide the label securement. The label and wall depressions (53) of the container and the mold projections (72) that provide these depressions are preferably arranged in a repeating pattern of rows that are inclined in a crossing relationship preferably at 45 degrees with respect to the vertical direction of the container. Each depression (53) preferably has a square shape formed by the square shape of the associated mold projection such that the vacuum passages (74) have a generally straight shape. During the plastic blow molding, the polyethylene terephthalate is preferably stretched to provide biaxial orientation that strengthens the resultant container.

A container comprising: a blow molding made of polyethylene terephthalate and including a noncylindrical wall of a generally uniform thickness having an outer surface; at least one label secured to the outer surface of the wall by in-mold labeling and having upper, lower, and side edges defining junctions with the wall; said wall having abrupt curvatures at the edges of the label to provide a smooth transition at the junctions between the label edges and the outer surface of the wall; the outer surface of the wall outside the perimeter of the label having a relatively smooth surface finish; the outer surface of the label and the outer surface of the wall within the perimeter of the label having a textured surface including isolated depressions; and said label and wall within the perimeter of the label having a combined generally uniform thickness.
