In-Mold Labeling (IML)

In-Mold Labeling That Performs with Precision and Impact

At Sussex IM, in-mold labeling (IML) is engineered into the injection molding process. Our in-house automation and engineering teams design, build, and maintain custom IML work cells that deliver reliable, repeatable results across industries. With over 30 years of hands-on experience in in-mold labeling and decorating, we help customers achieve durable graphics, consistent placement, and streamlined production – all under one roof.

From premium cosmetics packaging to rugged industrial parts, we support a wide range of applications and substrates with IML systems built for speed and precision.

What Is In-Mold Labeling?

In-mold labeling integrates the label into the part during the injection molding process. Rather than applying adhesives or post-mold graphics, the label is fused with the plastic using heat and pressure as the part is formed.

This creates a permanent bond, delivering high-resolution decoration without the risk of peeling, scuffing, or misalignment.

Why Choose IML?

Durability

IML decorations are built to last. Labels remain intact through moisture, heat, abrasion, and heavy use.

Visual Quality

IML supports photo-quality, digitally printed graphics in vibrant, full-color designs. Choose from gloss, matte, metallic, or soft-touch substrates to match your brand aesthetic.

Production Efficiency

Eliminates the need for secondary decoration processes. That means fewer steps, less waste, and faster throughput.

Customization at Scale

Variable graphics, quick label swaps, and small-batch runs are all possible within the same production cycle; ideal for personalization or seasonal programs.
