IML(in mold labeling) for extrusion blow molding
What is IML?
The term “in mould labelling” is directly derived from the technique: a preprinted polypropylene (PP) label is placed in a mould. This mould has the shape of the end product, e.g. the shape of a butter tub.
Then the molten PP is added to the mould. It fuses with the label, and while curing, takes the shape of the mould. Result: label and packaging become one.
In mould labelling can be done in the following production processes:
- Injection moulding
- Blow moulding
When starting up an IML project it is important to not only inform the label suppliers about the final objective of the project, but also the other partners that are involved, such as the process machine, mould and automation partners. Exchanging the production parameters between all partners helps you to make each IML project a success!
