Abstract
An improved method for preparing a molded plastic container with embedded label in which the label contains one or more perforations to reduce blistering during the blow molding process. In a preferred embodiment, the perforations are larger on one side of the label than the other to facilitate the release of gases that otherwise would be trapped behind the label.
Claims36
A method for forming a product containing a label embedded therein by blow molding comprising:
- placing a pre-printed label in a mold, said label containing one or more perforations sufficient to lessen the entrapment of gases by the label during the molding process thereby preventing blistering;
- placing a parison of liquid plastic in the mold;
- blowing air into the mold to conform the liquid plastic to the shape of the mold;
- and
- cooling and curing the plastic in the shape of the product.
In a method for forming a molded product containing a label embedded therein the improvement comprising:
- placing a pre-printed label in a mold, said label containing one or more perforations sufficient to lessen the entrapment of gases by the label during the molding process thereby preventing blistering.
A label for use in forming a molded product containing the label embedded therein, said label comprising:
- a substrate;
- one or more perforations in the substrate sufficient to lessen the entrapment of gases by the label during molding thereby preventing blistering.
