In mold labeling, also called in mold labels or IML, is a method that involves the placement of a pre-printed polypropylene label (decorative film) into a mold prior to the formation of the plastic container. It makes the label merge with the molten plastic, creating a single product with a durable, high-quality label integrated into the container's surface.

As the molten plastic reaches the end of the barrel, the gate, which controls the injection of plastic, closes. The screw advances, pulling a predetermined volume of plastic through and building pressure within, readying it for injection. The mold tool's two components are held tightly together under high pressure or clamp pressure.
