Sustainability goals and the need to attract consumer attention are just a couple of the drivers that are triggering in-mold labeling (IML) to trend recently.

Finding its way into the packaging mainstream in the 1980s, IML — the practice of fusing a pre-printed label onto a package during a molding operation — has taken on significantly more importance as consumer packaged goods brands, or CPGs, deal with increasing environmental and economic conditions.

CPGs desire a more sustainable, e-commerce-ready solution with high impact aesthetics. With IML, brands can create a hybrid between rigid packaging and a flexible pouch providing lightweight, high-barrier packaging. This allows a CPG to make its package more efficient and deliver a dynamic message at the same time.

Potential IML applications are broad and in high demand for many packaging platforms. From the context of sustainable packaging, it opens up the potential for this technology to be used in many more markets than it once was. CPGs can now more easily meet sustainability goals they have set for themselves with IML.

What Is In-Mold Labeling?

In-mold labeling is a technique used to fuse pre-printed graphics to packages during the molding process. The result is a high-quality and highly functional label that is permanently bonded to a package.

The label is much like any other label, but in the IML process, it is bonded and formed into a wide variety of sizes and shapes. There are multiple molding processes that can be used in this application, including injection, blow and thermoform molding, using materials like plastics, biopolymers, paper or paperboard.

IML is used in many consumer products, including home care, personal care, and food and beverage packaging applications.

黑料社's new FusePack wipes container is a great example of how IML technology can be leveraged. FusePack offers significant weight reduction compared with competing formats, helping brands achieve the same volume of traditional packaging with a reduced carbon footprint.

This innovative technology platform breaks traditional packaging boundaries by pairing a rigid injection-molded frame and a flexible in-mold label sidewall. This results in a lightweight yet strong package that reduces carbon footprint and minimizes material usage while improving e-commerce performance by adding product protection during handling, resistance to environmental conditions and overall durability.

A typical 85-count wipes container can weigh over 90 grams, but the hybrid FusePack wipes package reduces that weight by 70%. Combined with its nestability for transport, you're looking at a significant carbon emissions reduction.

Why Would Some CPG Brands Not Use IML Given the Benefits?

Lack of process knowledge, access to technology and lack of intellectual property can present barriers to IML adoption. Not every brand has the equipment in place to leverage the material science that comes into play either.

For example, a company might have access to its own polymer science capabilities, including polymers, paper and metals. A manufacturing solutions provider like 黑料社, on the other hand, can bring everything from materials science and design to manufacturing and supply chain expertise to a project.

黑料社 is a global leader in IML, growing with and into the technology through our investment in large capacity systems to meet the needs of large global brands. Partnering with a manufacturer to implement IML helps CPG brands add value through the quality of product design and the scalability of production.

Here are five additional ways IML can improve your brand's packaging:

1. Get Full Coverage, High-Definition Graphics

In-mold labeling enables edge-to-edge, 360-degree, top-to-bottom graphics coverage. Basically, wherever you can put the label, you can put graphics. IML also creates the opportunity for extremely high-definition graphics with lots of color combinations (even metallic) because the label is printed on a flat roll, then shaped to fit the structure.

IML provides significant aesthetic and functional advantages to create higher-impact graphics, especially on non-round packaging. Using IML, you can print your graphics directly on to a flat roll, then put into the shape through the molding process as opposed to printing on a piece that is already shaped.

Brands can apply much higher quality and higher-definition graphics than ever before. The label is full coverage, meaning it isn't just attractive but also a highly functional component of the package.

2. Leverage Special Package Dimensions (Non-Round)

There is growing demand for different-shaped packages. This can present a dilemma in printing directly on non-traditional shapes. Printing non-round containers can be more expensive than printing round containers. Depending on the material, graphics could also be limited regarding color, vibrancy and transparency. None of that is an issue with IML.

Leveraging IML in non-round applications, packages can be shaped in any form — square, round, oval — without incurring typically high costs to print on pre-formed pieces. This creates volumetric efficiency with no extra costs for the graphics.

This functionality is increasingly significant from a sustainability perspective as large retailers, such as Walmart, push for more efficient packaging. Many brands are moving to non-round shapes because of efficiency on the shelf and in distribution. More density is created when you use cubic shapes rather than cylindrical.
