Key considerations of in mold labeling system

An In-Mold Labeling (IML) system is a technology used in the plastic injection molding process where a pre-printed label is placed inside the mold cavity before the injection of plastic. This results in the label being permanently bonded to the container or part during the molding process, creating a seamless and durable design.

Key Considerations:

1. Mold Design: The mold must be designed to accommodate the label placement, and the label must be positioned precisely to ensure proper adhesion.

2. Label Materials: The label material should be chosen based on the plastic resin used for the container to ensure proper bonding and durability.

3. Label Alignment: In-mold labeling systems often include advanced automation for precise label placement and alignment inside the mold.

4. Injection Molding Parameters: The injection pressure, speed, and temperature need to be optimized to ensure that the label adheres properly without distorting or damaging it.

Types of In-Mold Labeling:

1. IML for Thinwall Containers: Used for lightweight packaging, like yogurt cups or snack containers.

2. Full-Surface IML: Covers the entire surface of the container for a fully decorated product.

 

3. 3D In-Mold Labeling: Involves using labels that wrap around the entire container, providing a 360-degree design.
