In-mold labeling (IML) is a process where a pre-printed label is inserted into a mold before the plastic is injected. When the plastic is molded, it forms around the label, creating a seamless, durable label that is integrated into the molded part.

IML is commonly used in the manufacturing of plastic containers, such as yogurt cups, food packaging, and medical devices. The benefits of in-mold labeling include high-quality graphics, resistance to scratches and scuffing, and the ability to customize branding and labels for each container.

The IML process also helps to reduce waste, as the label and container are made from the same material and can be recycled together. This makes it an environmentally friendly option for packaging and labeling.
