A deep dive into the mould labeling process

In Mould Labeling (IML) is an innovative technology that revolutionizes product labeling. It enables manufacturers to create high-quality labels that can be applied directly onto plastic containers or boxes during moulding. This provides a fast and efficient way of using labels, eliminating the need for adhesive or other materials.

According to a research 

The global in-mould labeling market size was valued at USD 2.54 billion in 2020 and is projected to reach USD 4.15 billion by 2026, growing at a CAGR of 8.3% during the forecast period.


By using IML processes, manufacturers can save time, reduce costs, and create more attractive product packaging. Besides the aesthetic appeal of IML labels, they also provide essential information to customers on the product, such as ingredients, nutritional facts, contact information, and more.

In this blog, you’ll learn about the benefits of IML labeling, its application process and techniques, and tips for selecting the best labels for specific products. Let’s dive!

Explanation of the mould labeling process

The in-mould labeling process is an integral part of the manufacturing process for medical devices. It involves carefully applying labels to the moulded product with a durable, high-performance adhesive that can withstand harsh manufacturing conditions and intense heat and pressure during sterilization.

Here are the steps  to the mould labeling process:

  • Preparing the labeling material

The label material and adhesive must be chosen carefully to withstand all conditions encountered during production and sterilization.

  • Applying the label

It is very obvious that the label must be applied accurately, with no air bubbles or creases. The material must also be firmly pressed against the mould to adhere correctly.

  • Curing and Inspecting

After applying the label, it must be cured in an oven or other heat source so that the adhesive bonds securely with the product’s surface. Once cooled, a quality assurance inspector will carefully examine the label for imperfections or failures.

  • Confirming compliance

Once the labels are inspected and approved, they must be checked to meet all safety standards and regulations. This includes checking that any information on the label is accurate and easy to read by consumers.

Benefits of mould labeling

In mould labeling (IML) benefits the packaging and labeling industry. Not only does it offer a more streamlined production process, but it also saves time and money. 

Do you know?

From increased product safety and improved aesthetics to better shelf presence and reduced environmental impact, IML helps businesses maximize their efficiency while maintaining high product standards.

  • One of the critical advantages of IML is its ability to create an attractive, consistent finish on products. 
  • By printing and cutting labels in a mould before final packaging, businesses can ensure a uniform appearance across all their products. 
  • IML is also much more efficient than traditional labeling methods, which can be labor-intensive and time-consuming. 
  • By printing in-mould labels directly onto products during manufacturing, businesses can speed up production times and streamline operations. 
  • Finally, IML offers significant environmental advantages over traditional labeling processes. 
  • IML reduces waste and helps businesses reduce their carbon footprint by eliminating the need for adhesives or secondary materials. This is especially beneficial for companies looking to become more sustainable.

Factors to consider when choosing mould labeling

Some factors to consider while choosing In-mould Labeling are as below. 

  • Durability

The label should withstand the high temperatures and chemicals used in molding processes.

  • Chemical resistance

It should also be resistant to any cleaning agents used in the process.

  • Flexibility

Choose a label that can bend and conform to the shape of the mould, allowing it to fit accurately and securely.

  • Adhesion

The label should be able to stick properly in any kind of environment, even one with high temperature or moisture.

  • Cost-effectiveness

Consider labels that are cost-effective and can be used multiple times without needing to be replaced frequently.

  • Customization

Look for a label that can accommodate text, logos, and any other customized information required for the mold.

  • Quick installation

Choose a label that is easy to install and remove from the mould without causing damage or disruption to the molding process.

  • Quality

The label should be high quality and have a long life span to withstand the wear and tear of frequent use.

  • Environmentally friendly

Look for labels made from recycled materials with minimal environmental impact.
