Since 1983
The Unrivaled Labeling Solution for Plastic Durable Goods for Over 40 years.
Polymer Fusion Labels do not contain any inks or adhesives; they are made of 100% compatible plastic. Unlike traditional labeling methods for plastic, it is the only label for durable plastics, guaranteed for the life of your product. No replacements needed.
The problem with labeling plastic is that it rejects foreign material, including inks and adhesives. Our founder flipped this problem on its head with a simple solution: a Polymer Fusion Label made of plastic, called Mold In Graphics®.
The value of our technology really shines when you start to look at the ROI. Millions of dollars in product is scrapped due to failed branding, warning, and tracking labels. With Polymer Fusion Labeling, you can kiss failed labels goodbye.
Our labels are specially made for durable plastics in the Polyolefin family, like Polyethylene and Polypropylene. We made our name in the Rotomolding industry, but have also expanded into many other industries such as injection molding, blow molding and thermoforming. Check out our other website at polyfuze.com
What Makes
Polymer Fusion Different?
Traditional Labels Vs. Polymer Fusion Labeling
Traditional Labeling: Pressure Sensitive Label
A sticker peeling off from plastic, with fading and cracked brand and warning messaging overtime. This does not bond to plastic on a molecular level, only temporary on the surface of the part.
- Adhesive failures lead to label removal
- Not guaranteed permanent for plastics
- Fails UV, Chemicals and Weather testing
Polymer Fusion Labeling
Unlike stickers, pad printing, or adhesives that fail over time, Polymer Fusion bonds at the molecular level to your product. It becomes part of the plastic itself, ensuring durability for the life of the product.
- No adhesives, no secondary coatings
- Guaranteed to last the product’s lifetime
- Withstands extreme environments (chemicals, UV, impact, weathering)
- Works on rotomolded and blow-molded products
How It Works
The Polymer fusion process
How Polymer Fusion Begins:
- A) Fusion Begins with Compatibility – The label and product are made from the same material, allowing for a seamless fusion.
- B) Heat & Pressure Activate the Process – The label fuses into the surface of the plastic.
- C) The Label Becomes Permanent – Unlike stickers, there’s nothing to peel, scratch, or degrade over time.
Cost of Inaction vs. Value of Change
Traditional labels may seem cheaper upfront,
but what about reapplication, compliance risks, and lost branding?
Initial Costs
- Stickers seem cheap
- Fusion slightly higher upfront
5-Year Costs
- Stickers need replacement
- Stickers need reapplication
- Stickers compliance risk
- Fusion = no extra costs
Brand & Compliance Risks
- Traditional labels fail
- Polymer Fusion labels stay intact
- Sticker Replacements : Labor-intensive, costly, and unreliable.
- Regulatory Issues: Safety & compliance labels that degrade lead to liability risks.
- Brand Damage: Worn-off labels make your product look low quality.
Regulatory & Compliance Advantages
"Built to Last – Just Like Your Product."
Because Polymer Fusion Labels become an actual part of your plastic durable good, they inherently take on the same properties as the host plastic. That means if your part is required to meet regulatory standards for durability, chemical resistance, or long-term legibility, your label will meet those same requirements—without the risk of failure.
Whether it’s an industrial container that must display critical chemical safety information, a medical device requiring permanent identification, or a waste bin needing long-term branding, Polymer Fusion Labels will perform as intended for the full life of the product.

The Solution
A Label For Plastic,
Made of Plastic.
Where traditional labeling methods attempt to stick to the surface of a non-stick plastic, Polymer Fusion Labeling approaches the problem in an entirely different way. Because our labels are comprised of 100% compatible plastic polymers, they can be fused into a plastic part, combining the two for a lifetime of use.
Discover Mold In Graphic Systems®
The Fusion Solution You Can Trust
Since 1983, Mold In Graphic Systems® has been the trusted name in durable labeling for plastic products. Our Polymer Fusion Labels don’t peel, crack, or fade. Instead, they fuse directly into the plastic, becoming a permanent part of your product.
Unlike traditional labels, our technology guarantees that your branding stays sharp and intact for the entire life of your product—no replacements needed.
What Makes Mold In Graphics® Unique?
Our labels are made from the same type of plastic as your product. This allows them to fuse into the surface, creating a permanent, lasting bond. No adhesives, coatings, or extra layers to fail over time.
Rain, sunlight, chemicals, or abrasion? Our labels can handle it all. They’re built to perform in even the harshest conditions.
Customers who used Mold In Graphics® decades ago still report that their labels look as good as new, even after 10, 20, or 30 years.
The Problem
Polyolefin Thermoplastics Are Hard To Decorate
Durable plastics are extremely difficult to permanently label. Polyolefin plastics have a very low surface energy (nothing sticks to them), expand and contract often, are exposed to all kinds of harsh environments and processes, and refuse to be permanently labeled by traditional methods such as stickers, screen printing, or adhesive-based in-mold labels.
The "stickiness", of plastic is about the same as Teflon®, meaning that adhesive-based labels will not remain in place long-term.
Plastic expands and contracts at high rates, causing labels to peel away as temperatures cause the part to grow and shrink in size.
Plastic goes through a microscopic process called "outgassing", where air is released through the surface of the part, causing labels to bubble and peel.
Why Other Labels Fall Short
Some companies claim their labels are permanent, but the reality is that many labeling technologies fail when it matters most:
- Pressure Sensitive Adhesive Labels: These rely on sticky adhesives that degrade over time, especially when exposed to moisture, heat or chemicals. This causes the labels to peel, crack, or completely fall off.
- Pad Printing: Inks used in pad printing only sit on the surface of the placti. Abrasion, UV exposure, or cleaning chemicals can cause the graphics to fade or wear off quickly.
- Screen Printing: While screen pringting provides initial vibrancy, the inks are prone to cracking, peeling or washing away under heavy use or harsh conditions.
- Substrates Like Teslin: These contain a small amount of polyolefin mixed with fillers, which creates a weak bond. Over time, their protective coatings break down, leaivng behind unsightly white residue—or no label at all.
No matter the method, these traditional technologies all share one flaw, they rely on surface-level adhesion, which fails over time.
