Discover how In-Mould Labelling (IML) works, its key advantages, and its applications in plastic packaging manufacturing. Explore ScalaRobotic's advanced IML robot solutions.
IML (In-Mold Labeling) is a modern manufacturing technology used in plastic injection molding that enables the label to be permanently applied to the product surface during the molding process.
Unlike traditional labeling methods, where the label is applied after the product has been manufactured, IML technology places the label directly inside the mold before the injection process begins. When the molten plastic is injected into the mold, the label becomes an integral part of the product, creating a single unified structure.
Thanks to its high print quality, long-lasting durability, aesthetic appearance, and production efficiency, IML technology is widely preferred, especially in the plastic packaging industry.
How Does the IML System Work?
The IML production process is carried out entirely by automated robotic systems. Every stage of production is precisely controlled to ensure consistently high quality standards.
The basic operating steps are as follows:
1. Label Preparation
IML labels are produced using specialized printing techniques and placed into the feeding system, allowing the robot to pick them up easily.
2. Robot Picks Up the Label
The IML robot uses a vacuum gripper system to accurately pick up the label and transport it to the injection mold.
3. Label Placement Inside the Mold
The robot places the label inside the mold with sub-millimeter precision. The label is secured to the mold surface using vacuum or electrostatic systems.
4. Plastic Injection
Molten plastic is injected into the mold, where it fully bonds with the label to create a single-piece structure.
5. Product Removal
After the cooling process, the robot removes the finished product from the mold and transfers it to the conveyor system. The product leaves the production line fully labeled and ready for use.
Advantages of IML Technology
Superior Visual Quality
High-resolution printing provides products with an attractive appearance and helps them stand out on store shelves.
High Durability
Since the label becomes an integral part of the product, it offers excellent resistance against scratching, peeling, moisture, water, and chemicals.
Hygienic Production
As the label is not applied afterward, there are no gaps where bacteria can accumulate. This makes IML particularly advantageous for food packaging applications.
Production Efficiency
Since the labeling process is completed during production, no additional labeling operation is required, helping optimize cycle times.
Easy Recycling
Because the label and the product are typically made from the same plastic material, the recycling process becomes much simpler.
Which Industries Use IML?
IML technology is widely used across various manufacturing industries.
The main application areas include:
- Food packaging
- Yogurt containers
- Ice cream containers
- Margarine tubs
- Paint buckets
- Detergent packaging
- Chemical product containers
- Industrial plastic buckets
- Household and kitchen products
The Importance of IML Robots
The precision of robotic systems plays a critical role in achieving maximum efficiency in IML production.
Accurate label pickup, precise placement inside the mold, and safe product handling directly affect both production quality and cycle time.
For this reason, modern manufacturing facilities prefer high-speed, servo-controlled, and highly reliable IML robotic systems.
