In today’s race toward sustainable packaging, many brands face a frustrating paradox: eco-friendly often feels like costly and complicated. But what if the solution wasn’t about choosing between performance and sustainability, but optimizing how you deliver both?
Welcome to the new frontier of low-coat-weight barrier coatings, where smarter science meets streamlined efficiency. At Impermea Materials, we’re proving that less coating doesn’t mean less performance. In fact, it means more: greater efficiency, increased compliance, and added value.
What Is Coat Weight, and Why Should You Care?
In technical terms, coat weight refers to the amount of barrier material applied to a substrate, typically measured in grams per square meter (gsm). Traditional coatings, especially those based on plastic or fluorinated materials, rely on high coat weights to achieve basic performance in terms of oil, water, or oxygen resistance.
But high coat weights come at a cost:
- Increased material usage
- Higher applied cost per unit
- Greater weight in transportation (and emissions)
- Reduced recyclability and repulpability
How Impermea Flips the Script on Coating Efficiency
Our proprietary barrier technologies are engineered to deliver maximum performance at minimum application weights. In many cases, Impermea’s coatings use up to 75% less material than conventional alternatives while achieving superior oil & grease resistance (OGR), moisture vapor transmission rate (MVTR), and oxygen transmission rate (OTR) metrics.
This is not just theoretical. Products like:
- OLEO-PAK 4100 – Exceptional oil resistance for frozen and take-out food containers
- HYDRO-PAK + MVTR 4040 – Low MVTR barrier for dry goods and perishables
- BIO-PAK + MVTR 4140 – Compostable, repulpable, and recyclable, with no performance compromise
...are already showing what’s possible when barrier science is reimagined for sustainability.
Lower Coat Weights = Lower Costs
By concentrating performance into leaner applications, Impermea helps brands achieve:
- Lower applied cost per square meter
- Faster run speeds (less drying time)
- Fewer formulation steps (single-step coatings)
- Less machine downtime and cleaning
In other words, low coat weight doesn’t just mean eco-friendly, it means economically smart. These benefits are particularly impactful for high-volume packaging and converters seeking scalable sustainability solutions.
Eco Without the Ego: Validated, Compliant, and Ready to Run
Unlike many green claims, our coatings are independently verified and comply with the US FDA's regulations (21 CFR 176.170 & 176.180). They are also compostable, recyclable, and repulpable, designed to meet the demands of sustainability officers, R&D leaders, and regulators alike.
And the best part? No new equipment is needed. Our solutions are plug-and-play on existing flexo, gravure, and rod coating lines.
Less Is More. But Also… Just Better.
