What is the Difference Between In Mold Labeling, Film Insert Molding, and In Mold Decorating?
October 9, 2023 • Posted in In Mold Labeling
At Sanwa Screen USA, we pride ourselves on offering high-quality In Mold Labeling (IML), Film Insert Molding (FIM), and In Mold Decorating (IMD) services for over 44 years.
During this time, we’ve fielded a lot of questions about the differences between In-Mold Labeling, Film Insert Molding, and In-Mold Decorating.
If you’re looking to understand the difference between the three, and how each process relates to your project and design needs, we’ve put together a bit of information on the history and background of each service.
Truthfully, the terms are often used interchangeably — and with Sanwa, there’s no need to worry that you’re asking for the wrong service for your products. You can rest assured that our team will spend the time to learn about your products and goals, and then employ the best methods to meet your needs.
Definition of In Mold Labeling
In Mold Labeling (IML) is the process used to directly label a product during the injection molding cycle. The label serves as an integrated part of the final product, removing the need for additional branding materials (such as paper, plastic, adhesives and more). Typically, these products have a lifespan of a few weeks or a few months.
Definition of Film Insert Molding
Film Insert Molding (FIM) is often used reciprocally with IML. A silk screen printed graphic is formed and placed into the injection mold cavity — then speed, pressure, and temperature are all carefully dialed in to produce a high quality molded part.
Definition of In Mold Decorating
In Mold Decorating (IMD) also describes the process for decorating a plastic part during the injection molding cycle. However, this term typically refers to its use in applications that require a longer life span, measured in years or even decades.
Examples of shorter lifespan products include food containers, cosmetics, or household products.
Examples of longer lifespan products include automotive decals, appliances, medical devices, and consumer electronics.
A History of Terminology
There was a time when the term you used (IML, FIM, or IMD) simply depended on your geography.
The In Mold Labeling process came around in the 1970s, offering an alternative to decals and paper labels. And as the process developed over the next several decades, some countries and regions settled into calling the process IML, while others called it FIM or IMD.
Today, within the industry, there is a slight distinction between the two that typically refers to the types of products being printed on, and the materials used to achieve a desired effect.
However, customers typically don’t have to worry about asking for the right or wrong process for their product — a manufacturer with experience and proclivity to innovative solutions will make certain your specific goals are achieved. That’s what we’re here for.
Benefits of In Mold Labeling, Film Insert Molding, and In Mold Decorating
The technology provides a host of benefits for the discerning manufacturer and end user. All three offer high-quality graphic solutions with the elimination of secondary labels or adhesives, and they offer a wide range of color, size, texture and graphic options.
Other benefits include:
Durability
Flexibility (in size runs and additional treatments)
Cost effectiveness
Waste reduction
Visual appeal
Time savings
Design Options
IML, FIM, and IMD can all be used alongside our other manufacturing capabilities to create unique and highly custom plastic parts. Design options include:
Dead front or black-lit touch
Fine expression silk printing (FESP) for high definition patterns and textures
Anti-finger print, anti-gloss, and anti-reflective finishes
Matte, satin or gloss finishes on the same part
Inks that function with capacitive touch buttons
