In Mold Coating

In-mold labeling (IML) is a labeling method in which a pre-printed decorative film is placed into a mold before the plastic container is shaped into that mold. Plastic pellets or resin are heated and placed into the mold where it merges with the label to create a single product.

Description

In-mold labeling is most commonly used for thin-walled disposable items like consumer packaging that have a shorter shelf life. Companies in food, personal care, household and cosmetic industries often use IML to brand their packaging.

Plastic containers with in-mold labeling are manufactured through two methods: injection molding and blow molding.

Key benefits

01/

Complex Curved Geometry Available

Dedicated forming process prior to injection molding forms IML film deep draw and complicated geometry.

02/

IML Film Layer Protection

Graphic layer is fully protected from abrasion by IML film. Additional functionalities like UV or chemical resistance is available by special films.

03/

Environmental Friendly

Thin IML ink is only applied to the area where decoration is needed. Volatile organic compounds can be reduced.

04/

Production Lot Flexibility

Allows flexible manufacturing. Silk-screen printing for lower volume production, Gravure printing for higher volume production.

05/

Versatile Surface Finish

Unique coating and printing technology can create excellent natural finishes including tactile texture, effects like stainless steel, natural wood, and fabric-like patterns.

Process

IML process consists of multiple steps – printing, forming, trimming and molding.

Because of the dedicated forming process, IML process is well suited for deeper draw parts and complicated geometries.

Also, since the carrier film remains on the surface with the IML process, a high-quality exterior with excellent physical properties and a sense of depth can be achieved.
