Abstract
The present invention relates to an in-mold label having a roughened inside surface to engage an article being molded in the mold. This roughened inside surface reduces air-entrapped blistering formed during molding, the air-entrapped blisters being between the label and the molded article. Preferably the label includes a plurality of perforations therein. To create the roughened inside surface at the time of perforating the label, the perforations are made by needles passing from the outside or exterior surface of the label through the inside surface thereby creating burrs on the inside surface; the inside surface being the surface which will engage the article to be molded. The label also preferably, in addition to the plurality of perforations and roughened inside surface, includes adhesive in a pattern on the inside surface.
