What Is In-Mould Labeling (IML)?

In-Mould Labeling (IML) is a modern printing and packaging technology in which the printed label is placed directly into the injection mould. When molten plastic is injected, the label fuses seamlessly into the product surface, creating a fully integrated, ultra-durable, premium-looking finish.

By combining printing and molding in a single step, IML has become the leading solution for food packaging, cosmetics, household goods, and industrial containers.

How IML Works

The IML process includes three main stages:

Label preparation

The label is printed on high-quality PP/PE film that is recyclable, heat-resistant, and safe for food packaging.

Label placement inside the mould

A robot or trained operator places the label into the mould cavity in a precise fixed position.

Injection molding – forming a one-piece product

Molten plastic is injected into the mould → The label bonds permanently to the product → The result is a ready-made plastic packaging with a built-in label.

The product comes out of the mould perfectly finished—no post-printing required.

Advantages of IML

Superior aesthetics

Vibrant, high-resolution colors
No peeling, smudging, or scratching
Full 360° printing capability

Exceptional durability

Water-, impact-, and heat-resistant
UV-resistant, suitable for outdoor storage
Suitable for cold storage or freezing

Cost-effective for mass production

Printing + molding in one step
Ideal for automated production lines

Eco-friendly and safe

Labels and containers are both PP → 100% recyclable
Food-contact safe

Limitations of IML

Higher upfront investment in molds, robots, and label materials
Not ideal for very small orders
Requires specialized injection molding machines and trained technicians

Common Applications of IML

Types of IML Labels

IML PP (Polypropylene): most popular, ideal for injection molding
IML PE (Polyethylene): used for flexible or impact-resistant products
Metalized IML: metallic premium effect
Transparent IML: high-end appearance, allows product visibility
