The main element of in-mold labeling is to cover a product with a label or design layer.

The in-mold labeling (IML) process begins with selecting a material for labeling, according to the type of material to be labeled. A few of the materials to be used as labels are paper, polypropylene and polystyrene. It can also be used for a label in a material similar to the molded part.
It is used as a label for materials containing cavitation. The material of the cavitation label is a sponge-like layer bonded between two thin layers. In cases where abrasion is of great importance, laminated film is used as a label.

After material selection, the label is directed to the open mold and it is firmly placed in the mold cavity with clamp, vacuum, static electricity, compressed air. In the next stage, the selected plastic material is melted and injected into the mold. After the injected material is cooled down, the product is attached to the label. In the last stage, a beautiful design is made on the molded product, and in-mold labeling takes its final form.
