In-Mould Labels (IML Labelling)
IML (In-Mould Labelling) is a technology in which a pre-manufactured label is placed in the mould and becomes one with the packaging during injection moulding, making it indelible. The technique is used worldwide for blow moulded bottles as well as injection moulded and thermoformed containers. In mould labeling is very different from other labeling methods, and that difference begins before the container is formed. At the front end of the moulding cycle, just after the previously formed container is ejected from the mould, In-mould labels are inserted into the mould before it closes and are held in place with a vacuum or a static charge. There they wait for the plastic to be blown or injected into the mould, embedding the labels into the wall of the container during the moulding process and displacing container resin equal to the volume of the label. The big difference with In-mould labels is that the product is in the wall of the container. All others are glued onto the outer surface of the container.
