In-Mold Labeling (IML) In mold coating is an advanced decoration technology where pre-printed labels are inserted into the mold and fused with plastic products during injection molding.
This process ensures seamless integration between the label and the container, delivering superior durability, high-resolution graphics, and scratch resistance.
Key Benefits
- No peeling or bubbling
- High-quality printing effect
- Moisture and chemical resistance
- Eco-friendly (no secondary labeling process)
Process Flow
1. Printing
For IML film, Nissha has two printing methods – Gravure printing and Silk screen printing. Depending on design specification and production volume, the best printing method is chosen.
2. Forming and Trimming
IML film is set in the forming machine and formed into the geometry of the part's shape by high heat or high pressure. Then the periphery film is trimmed by die cut machine or laser.
3. IML molding
Formed IML film is inserted into the injection molding tool and combined with resin.
4. Product
After injection molding, the result is finished decorated products.
