What It Takes to Win Our Investment in Non-Plastic Barrier Coatings for Fiber
That “if” is where we spend most of our time. We look at a lot of barrier coating technologies — resins, dispersions, biopolymers, mineral coatings, hybrid multilayer systems — all promising to replace PE, PVDC, or wax on paper and board. Very few of them are actually investable. The gap between laboratory innovation and market adoption is not technology alone; it requires readiness across an entire system of technical performance, manufacturing capability, sustainability impacts, and commercial economics. This post lays out the framework we use and what we’ve learned from the ones that didn’t make it.
Sizing the opportunity — and why now
Barrier coatings for packaging is already a multi-billion-dollar global category, and most estimates put it in the low-to-mid teens of billions of dollars today, growing at a high single-digit to low double-digit CAGR through the early 2030s. The water-based and bio-based segment — the part of that market that’s actually relevant to a fiber-recyclability thesis — is growing meaningfully faster than the category as a whole, because it’s the only segment that lets a package hit both a barrier spec and a recyclability spec at the same time. Fiber-based packaging broadly is on an even steeper trajectory, with several forecasts pointing toward a multi-hundred-billion-dollar global market by the mid-2030s as e-commerce volume and plastic substitution both compound. CPG companies, brands, and packaging suppliers are committing to reduce plastic, meet recyclability targets, and comply with evolving regulations such as Extended Producer Responsibility (EPR) — all while consumer expectations for product quality, shelf life, and convenience keep rising.
What’s changed recently isn’t the size of the number; it’s the certainty behind it. Four things have moved in the last 18-24 months that make this a “now” problem rather than a “someday” problem for brands:
- EPR laws went from theoretical to real dollars. Oregon and Colorado are now actually collecting fees, with California, Maine, Maryland, Minnesota, and Washington phasing in behind them. Packaging such as flexible film that was purchased because it was the cheapest option is increasingly a liability from an EPR fee perspective, because fiber-based structures are more recyclable.
- Plastic source-reduction mandates are creating real pressure. California’s EPR law, for instance, includes an aggressive mandate to reduce single-use plastic by 25% by 2032, with interim targets in 2027 and 2030.
- Labeling laws turned claims into legal exposure. More on this below, but the short version is that brands can no longer market their way around a coating that doesn’t perform.
- Brand-level 2025-2030 packaging commitments are coming due. A wave of food, beverage, and personal-care brands set public recyclability and plastic-reduction targets for this window, and procurement teams are now actively sourcing to hit them, not just writing about them in sustainability reports.
That combination of real fee exposure, real compliance deadlines, and real legal exposure is what’s pulling capital and attention into this category right now, and why we think the next three to five years are the right window to be underwriting it.
The industry challenge is clear: how do we deliver high barrier performance in structures that are recyclable, legally compliant, and cost-competitive at scale? That requires a new generation of coating technologies that perform across:
- High-speed converting environments, including processes like
- Horizontal/Vertical Form Fill and Seal (HFFS/VFFS), printing, and lamination
- Heat sealing and forming windows
- Shelf-life and migration performance
- Fiber recovery and recycling system acceptance
- Cost parity at commercial scale
For now, paper-based and mono-material solutions are among the most promising pathways. But replacing plastic or aluminum barriers is not a one-to-one substitution problem: it requires system-level compatibility across chemistry, process, and end use.
Based on Atlantic’s 80-year history in packaging and our deep customer connections, here are the rules we play by when it comes to evaluating packaging materials and technologies.
1. It has to perform as a barrier, full stop
This sounds obvious, but it’s the first filter, not an afterthought. A coating that’s beautifully recyclable and dirt cheap is worthless if it doesn’t hold moisture, oxygen, or grease out of the package for the product’s actual shelf life.
We look for demonstrated performance across the barrier properties that matter for the target application: water vapor transmission rate (WVTR), oxygen transmission rate (OTR), grease and oil resistance (KIT rating or equivalent), heat-seal integrity, and durability through the customer’s real supply chain (not just a lab shelf). Performance has to hold up across humidity and temperature ranges, not just at bench conditions. We often see data from flat sheets, which is a useful start, but there’s a real gap once that same coating is converted into 3D articles — bags, sachets, pouches, wrappers. Even a simple crease can break otherwise spectacular performance, and that gap is where a lot of technical feasibility stories fall apart.
We rely heavily on our technical advisors here. This is genuinely a “bring in the experts” category, and we’ll be filling in more specific thresholds and test protocols as this piece evolves. Directionally, we’re looking for coatings that can credibly compete with the incumbent plastic or wax structure on function, not simply on a sustainability story.
2. Demonstrably recyclable
“Recyclable” is a claim. We want evidence. Two separate reasons make this non-negotiable, not just nice-to-have:
Brands need it. No major CPG or retail procurement team is going to specify a coating into their supply chain on a technical data sheet and a promise. They need recognized third-party testing they can point to internally, hand to their sustainability and legal teams, and put behind a claim on pack. If a coating can’t produce that paperwork, it doesn’t matter how good the chemistry is… — it will not clear procurement.
It’s the law, not just good practice. Making an unsubstantiated recyclability claim is a real legal problem today. The FTC’s Green Guides treat unqualified “recyclable” claims as a potential Section 5 violation if the material isn’t actually collected and reprocessed at scale. Laws like California’s SB 343 go further: starting October 2026, packaging can only carry the chasing-arrows symbol or the word “recyclable” if it clears a 60%-collection / 60%-sortation threshold statewide, and any packaging with intentionally added PFAS above 100 ppm is disqualified from a recyclability claim outright, regardless of anything else. Other states are moving in the same direction, and greenwashing litigation around recyclability claims is already active. That means our customers — the brands — are exposed to civil penalties and lawsuits if they can’t substantiate what’s on the label, and they will not take that risk on our behalf.
Practically, for fiber packaging, substantiation means passing repulpability and recyclability protocols — most commonly the Western Michigan University (WMU) Fibre Box Association (FBA) test protocols, Parts I and II, which score fiber yield and screen for contamination during repulping. A coating needs to release cleanly from the fiber, disperse or screen out during the pulping process, and not leave the mill with a mess of “stickies,” the adhesive and coating fragments that gum up equipment and degrade the recycled fiber. High fiber yield, clean screening, no stickies, and potential eligibility for a How2Recycle “widely recyclable” label or equivalent is the bar. Anything short of third-party test data from a recognized facility is a claim we treat with real skepticism, no matter how good the pitch deck slide looks, because that same skepticism is exactly what a brand’s legal team will apply.
3. Compostable is a “nice to have,” and we’re aware of the asterisk
We like compostability as an additional attribute, particularly for food-contact and foodservice applications where grease and moisture resistance are hardest to achieve without plastic or fluorochemicals. A coating that’s both recyclable through conventional paper streams and certifiable as compostable against test standards like ASTM D6868 and certifications such as BPI or TÜV Austria gives a customer optionality we find attractive.
But we’re going in with eyes open on where the category stands today. Composting infrastructure in the U.S. remains thin — most municipalities don’t have industrial facilities that accept packaging, and a meaningful share of the facilities that do exist have started rejecting compostable packaging outright because of perceived contamination risk to their finished compost. Regulators are responding in kind: several states are considering or have implemented rules that limit or ban even certified compostable packaging from compost streams. None of that is a knock on the material science; it’s a knock on the current status of the ecosystem around it.
4. Cost-competitive on total cost of ownership — not just coating price
The coating cost itself is rarely where the economics get decided. We evaluate cost on a total-cost-of-ownership (TCO) basis, which includes:
- Application cost — and specifically, compatibility with existing coaters and line speeds. This is one we weigh heavily and think gets underrated. A converter or mill has already sunk capital into its coating lines, and it is not going to rip out or meaningfully retrofit that equipment for a new chemistry unless it has no other choice. A coating that runs on existing coaters, at existing line speeds, with existing drying/curing setups, is a fundamentally easier sell than one that requires new equipment or materially slower throughput, even if it performs better on paper. Slower line speed is a direct hit to a converter’s output and margin, and it’s usually the first thing that kills a deal in commercial diligence. We want technologies that a converter can drop into their current infrastructure with minimal disruption.
- EPR fee exposure: with Extended Producer Responsibility programs now live or imminent in seven U.S. states (Oregon, Colorado, California, Maine, Maryland, Minnesota, and Washington), material choice directly changes a brand’s per-pound fee obligation. Eco-modulation is real money — bonuses for recyclable, mono-material, and PCR-content packaging, and material penalties running well over a dollar a pound for “not collected” categories. A coating that gets a package onto the recyclable list, or lowers its EPR fees, is worth real dollars to a brand before you even talk about the coating’s price per pound.
- Certification and testing cost: who pays for and maintains WMU/FBA testing, How2Recycle membership, and compostability certification, and what happens when the formulation drifts (a supplier swap, a new liner, a different adhesive) and retesting is required.
A coating that’s marginally more expensive per pound but runs on existing lines and meaningfully lowers a customer’s blended packaging cost once you account for EPR and compliance is a better investment than one that wins on coating price alone.
How we operationalize this: our readiness framework
To capture the criteria above in diligence, we evaluate every technology against four readiness pillars:
Technical Readiness – OTR and WVTR under relevant humidity and temperature – Heat seal strength and window – Grease, aroma, and mineral oil barrier (as applicable) – Blocking, coefficient of friction, and mechanical durability – Performance stability under stress and aging
Manufacturing Readiness – Coating uniformity and defect tolerance at line speed – Compatibility with existing coating and converting assets – Drying requirements and thermal stability – Scalability of materials and process repeatability – Run stability on HFFS/VFFS and lamination lines
Circularity & Regulatory Readiness – Fiber repulpability and recyclability (WMU Part I & Part II) – Recyclability validation (CEPI, Aticelca, How2Recycle) – Food contact compliance and regulatory approval – Absence of PFAS and restricted substances – Alignment with EPR and regional frameworks
Commercial Readiness – Total cost of ownership vs. incumbent solutions – Raw material availability and supply chain robustness – Platform potential across formats and geographies – Clear pathway to CPG qualification and scale – Risk profile for brand owners
What we check
Gate 1: Technical Feasibility
Can it perform?
Barrier performance (OTR, WVTR); heat seal strength and window; mechanical and functional performance; stability under environmental stress; lab-scale reproducibility
Gate 2: Process Scalability
Can it be made at scale?
Pilot-scale coating results; uniformity and defect control; compatibility with coating & converting; line-speed stability (HFFS/VFFS); process window and repeatability
Gate 3: Circular Compliance
Can it go into the right stream?
Fiber recovery (WMU Part I & II); recyclability validation (CEPI, Aticelca, etc.); regulatory and food contact compliance; absence of PFAS and restricted substances; alignment with EPR and regional rules
Gate 4: Commercial Readiness
Can it win in the market?
Total cost of ownership; supply chain and raw material security; platform potential across applications; clear path to CPG qualification; risk profile acceptable to brand owners
Success criteria
Meets or exceeds target performance at lab scale under relevant conditions
Demonstrated stability and repeatability at pilot or production-line speeds
Verified recyclability and regulatory acceptance in relevant markets
Competitive economics with a clear path to scale and adoption
What we’ve seen that doesn’t work
Anonymized, but pattern-matched across a lot of diligence calls:
- One coating, one product, one customer. This is the pattern we see most often, and it’s the hardest one to get past. A team has a single formulation that works well for a single application with a single prospective customer, and that’s the whole company. There’s no platform, no roadmap to a second chemistry or a second application, no path to a second or third customer if the first one changes their mind. That’s a services engagement or a licensing deal, not a venture investment. We need to see a technology platform that can extend across barrier types, substrates, or end markets — something we can underwrite as a business, not a bet on one deal closing.
- Coat weights that are too thick to repulp cleanly. Great barrier numbers, terrible fiber yield. The coating survives the pulping process instead of releasing from it.
- Compostable, but not recyclable, and marketed as if that’s the whole answer. A coating that’s certified compostable but fails repulpability testing puts all of its end-of-life eggs in the weakest basket: infrastructure that mostly doesn’t exist yet, with tough regulatory headwinds. We want recyclability tackled first, and ideally both pathways covered, or a clear-eyed acknowledgment of which one the customer will actually use.
- Certifications that are directional, not defensible. In-house lab data, a single non-representative test run, or a claim based on the coating’s general chemistry rather than the finished, converted structure. When we ask for the WMU test report or the BPI/TÜV certificate for the actual coated substrate, it isn’t there.
- Cost stories that ignore TCO. A coating priced competitively against virgin plastic film, but that requires a slower line speed, a capex-heavy retrofit, or lands the package in a high EPR fee tier. The “cost-competitive” claim doesn’t survive contact with a customer’s actual P&L.
Even with strong laboratory data, most technologies fail during one of a few predictable transitions: heat-seal instability under real-world variability; performance loss under humidity, temperature, or aging; poor machinability on high-speed lines; or an immature, non-scalable raw material supply chain. Strong lab performance without converting validation is the single most common false positive we see.
Why this is where a partner like NEV / Atlantic earns its keep
None of the four criteria above are independently hard to hit. What’s hard is hitting all four at the same time, proving it with real third-party data, and doing it fast enough to matter before a customer’s next packaging redesign cycle or EPR deadline.
That’s the gap we exist to close. We bring the technical relationships to get a coating properly tested — repulpability, barrier performance, and compostability certification — before a term sheet, not after. We know which claims hold up and which ones are a good story that hasn’t been put to the test at WMU yet.
There’s a harder problem underneath all of this, though, and it’s the one most start-ups underestimate: the jump from a validated formulation to a global brand customer is enormous, and most technologies never survive it. The biggest CPG and retail brands in the world do not want to be your first commercial trial.
This is where we think we’re most useful, and it’s a big part of why a partner like Atlantic / NEV matters. We are already inside the supply chain of the world’s biggest brands — through our existing portfolio, our converter and mill relationships, and the commercial relationships we’ve built over years in this space. That means we can get a promising coating in front of the right mid-market and SME customers first, let it prove itself commercially at a scale where the risk of a misstep is manageable, and build the real-world track record and volume data that a global brand will actually want to see before they commit. Once that proof point exists, we’re also the ones who can make the introduction to the brands that matter most.
