Dairy & yoghurt
For yoghurt, dairy products, ice cream, and other suitable chilled foods.
What is it?
IML means In-Mould Labelling. A printed label is placed inside the mould before the plastic container is formed. During moulding, the label becomes attached to the container surface, so the label and container are produced as one finished pack.
IML is commonly associated with injection-moulded tubs and containers. It is different from applying a sticker after the container has been made.
Where is it used?
IML packaging combines container functionality with integrated printed graphics for a range of food and non-food applications.
Food containers
For butter, spreads, dips, snacks, and selected ready-to-eat food products.
Paint & household
For paint, coatings, household products, and other suitable non-food applications.
Retail packaging
For products where clear graphics, branding, and shelf presentation are important.
Key benefits
Label integration
The label is applied during moulding rather than as a separate post-production step.
Quality graphics
High-quality printed graphics can support product information and shelf presentation.
Consistent placement
Properly controlled processes can help achieve consistent label positioning.
Durable finish
Integrated labels may resist peeling better than some separately applied labels.
Design flexibility
A range of container shapes and label designs may be possible, depending on tooling and machinery.
Materials & technologies
Common materials and processes
- Container resin: often polypropylene (PP) for many IML food tubs, although other combinations may exist.
- Label material: commonly a compatible plastic film selected for the container resin and moulding process.
- In-mould technology: a printed label is positioned in the mould and bonds with the container during moulding.
- Automation: robotic label placement and vision checks may be used on suitable production lines.
IML requires compatible labels, moulds, container materials, and process settings. Label artwork, position, container shape, and food-contact needs should be agreed before production.
Confirm whether the required product uses injection-moulded IML packaging. Not all labelled containers are made using IML.
Frequently asked questions
Is IML the same as a sticker?
No. A sticker is normally attached after the container is made. In IML, the label is placed in the mould and becomes integrated with the container during moulding.
Can IML containers be recycled?
It depends on the container and label materials, their compatibility, and local recycling systems. Ask the supplier for material and recyclability information.
Can IML be used for food packaging?
Yes, for suitable applications, provided the container, label, inks, and manufacturing process meet the relevant food-contact requirements.
