P-319 BLOW MOLDED POLYETHYLENE TEREPHTHALATE CONTAINER HAVING IML TEXTURED LABEL WALL AND METHOD FOR MAKING SAME 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.
