What is IML?
In-Mold Labeling (IML), is a technology that enables the labeling process to be carried out during the production of plastic injection or thermoforming products. IML refers to the integration of the label with the plastic product as a single unit during the molding process.
How Does it Work?
The IML process occurs as follows:1
Label Preparation: A pre-printed label, typically made from plastic materials such as polypropylene (PP), is produced and tailored to be compatible with the product.
2
Placement in the Mold: A robotic arm or an automated system places the label into the injection mold.
3
Production and Integrated Labeling: The plastic material (e.g., molten polypropylene) is injected into the mold, combining with the label to form a single integrated unit.
4
Final Product: Once production is complete, the label becomes an inseparable part of the product, embedded seamlessly on its surface.
Advantages
1
More Durable Labels: Since the label is not adhered to the surface, it does not peel, tear, or wear out.
2
Aesthetic Appearance: High-quality graphics seamlessly integrate with the product surface.
3
Eco-Friendly: Made from the same material as the plastic product, it facilitates easier recycling processes.
4
Efficiency: As the labeling process is integrated into production, it saves both time and costs.
5
Water and Chemical Resistance: Labels are more resilient against external factors.
6
Quick Design Changes: Transitioning from one design to another is highly efficient in in-mold labeling automation. There is virtually no production loss at the start of a new design.
Applications
Packaging
In products such as yogurt containers, ice cream tubs, and detergent bottles.
Food
Preferred due to its high hygiene standards.
Cosmetics
In the packaging of products such as shampoo bottles and creams.
Industrial Products
In areas requiring durability, such as chemical containers and oil canisters.
IML technology modernizes and streamlines production processes while also offering aesthetic and durability advantages.
