In-Mold-Labeling (IML) and In-Mold-Decoration (IMD) are injection-molding processes in which a flat, even film surfaces, textiles, or preformed film is back-molded.

In-Mold-Labeling is often used in the packaging industry as an alternative to printing when design requirements call for a high degree of flexibility or else when the impression cannot be directly molded on the part. The labels are usually a printed polypropylene film with a thickness of a few tenths of a millimeter. The advantage of In-Mold-Labeling is that it integrates a downstream process directly with the injection molding process. The disadvantage is a heat reduction caused by the label and the slightly reduced cycle times that this necessitates.

In-Mold-Decoration is a widely diversified technology concerned with the decoration of parts and is used in almost every branch of injection molding. In-Mold-Decoration can be as simple as transferring a printed impression on a flat polyester film of onto a part during or it may involve a complex back molding of textiles or preformed, three-dimensional parts.
