In-mould labelling (IML process) is the innovative labelling technology for plastic packaging. The procedure is sophisticated: pre-printed labels are placed in the injection moulding machine. This means that the labelling process takes place during the packaging production process, not afterwards. So, there is no need for a separate adhesive film because: when the liquid plastic is injected, the labels bind directly with the polymer melt. After cooling the label forms an inseparable unit with the packaging. Through this processing technology we create a recyclable single-material packaging – an important factor and one which is not to be underestimated.
