In-mould labelling is a type of labelling where a label is printed on plastic and applied to a mould before plastic is added. When the plastic is poured into the mould, the label and plastic become one piece and the label becomes part of the finished product. This type of labelling is often used on plastic items such as food containers, drink bottles, and toys. It makes packaging look better, and the label can't be removed so it helps to identify the product and make sure that it's safe and of good quality.
