Other Paperboard Container Manufacturing (U.S.)

NAICS 2022 code 322219 — an investor's primer

NAICS is the North American Industry Classification System, the standard code set the U.S. government uses to group businesses.

---

1. Overview

This industry makes the paperboard containers that are not boxes: the round cardboard tube inside a roll of paper towels, the spiral-wound "composite can" that holds Pringles chips, powdered drink mix, or frozen juice concentrate; the heavy fiber drum used to ship chemicals and food ingredients; the rigid "setup" gift and jewelry boxes that arrive pre-formed rather than folded flat; and the cardboard cores that paper mills, film makers, and textile plants wind their product onto. It buys paperboard and converts it into these shaped containers — it does not make the board itself.[1]

Why an investor should care: this is a small, mature, cyclical U.S. manufacturing niche — roughly $9.2 billion in annual shipments — but it is unusually consolidated and it sits at the center of two opposite stories. Some product lines (tubes and cores, fiber drums) rise and fall with industrial production, and some (like frozen-concentrate and snack composite cans) have been shrinking for decades. Other lines are riding a genuine tailwind as brands swap plastic and metal packaging for paper-based cans that recycle more easily.[3][7]

Public-market and private investors reach this industry differently. There is no pure-play public stock for it: the dominant public names — Sonoco Products, Greif, Graphic Packaging, and Huhtamaki — are diversified global packaging companies for whom these products are one segment among several. Private ownership, by contrast, is where most of the number of firms live: dozens of independent, often family-owned tube, core, drum, and rigid-box converters. We cover both routes in Sections 4 and 10.

2. What it is, and what it excludes

In scope (322219). The Census Bureau defines this industry as establishments that convert purchased paperboard into containers other than corrugated, solid-fiber, and folding boxes, without making the paperboard themselves.[1] In plain terms, four product families:

• Fiber cans, tubes, and cores — spiral-wound or convolute-wound tubes: composite food/consumer cans, mailing tubes, winding cores for paper/film/tape/textiles, and concrete-forming tubes (e.g., Sonoco's Sonotube brand).
• Fiber drums and similar shipping containers — all-fiber drums (ends may be metal or plastic) for dry chemicals, food ingredients, and industrial powders.
• Setup (rigid) paperboard boxes — dense chipboard boxes shipped already formed, used for luxury, gift, cosmetics, and electronics packaging.
• Non-folding sanitary food containers and liquid packaging — including certain milk cartons, cups, bowls, and food containers made from purchased paper or paperboard.[1]

Plants buy rolls or sheets of paperboard and then cut, wind, form, print, laminate, coat, glue and assemble them. Polyethylene and other coatings may provide moisture or grease resistance, meaning a "paper" package can still be a mixed-material structure.[15] Products are often engineered to a customer's dimensions, filling equipment, graphics and barrier requirements — a mixture of high-volume runs and changeover-intensive custom work. Sonoco says it generally works from customer forecasts, carries no significant backlog and aligns deliveries on a built-to-order basis.[5]

Explicitly excluded — and the adjacent NAICS codes to know:

That last row matters: the boundary between this industry and folding cartons (322212) and paperboard mills (322130) is where most of the confusion — and most of the vertical integration — happens (Section 5).[1]

Ownership mix. A barbell. A handful of large, publicly traded, vertically integrated corporations account for the bulk of revenue, while the long tail is independent private converters, many family-owned and decades old.

3. How big it is (federal figures)

From U.S. federal statistics for NAICS 322219:

A few things fall out of these numbers. Average pay is about $60,000 per worker (payroll ÷ employment)[2]. The typical firm is substantial for a "small" industry: roughly $58 million of revenue per firm ($9.18 billion ÷ 159)[3], and about $33 million per establishment[2][3] — this is capital-intensive factory work, not a cottage trade. The Small Business Administration (SBA) sets the small-business ceiling at a high 1,000 employees, reflecting how large the plants are.[4]

Establishment contraction. A trade-press analysis of Census County Business Patterns found 266 establishments in 2022, versus 348 in 2012 — a 24% contraction over the decade, consistent with ongoing consolidation.[16]

Undercount caveat — mostly the other direction here. Unlike industries dominated by tiny cash operators or government, this is an employer-establishment manufacturing sector that the Economic Census captures well; there is little informal activity to miss. The distortion runs the opposite way: the federal $9.2 billion counts only U.S. paperboard-container converting, whereas the public companies you'll read about (Sonoco, Greif) report global, all-segment revenues many times larger. Do not confuse a company's total sales with this industry's size. Some plant output is also captive — moved inside a vertically integrated firm rather than sold — so shipments can double-count board-plus-conversion within the same corporate family. The most common misreporting is to use "paperboard packaging" figures as though they measure 322219; the Paperboard Packaging Council, for example, describes a $10 billion North American paperboard-packaging market, but its scope is broader and heavily oriented toward folding cartons.[17]

4. The investable universe

There is no pure-play public company. The listed exposure is through diversified packaging groups; the pure-play players are private.

Public (diversified — this industry is one segment):

Adjacent but not primarily this industry: Smurfit WestRock (mainly corrugated and folding, some rigid boxes), Packaging Corporation of America and International Paper (primarily containerboard and corrugated), and the metal-can makers (Silgan, Crown, Ball) that composite cans compete against. Treat these as competitors/neighbors, not as ways to own 322219.

Private / other owners (the pure plays): independent tube-and-core and drum converters and rigid-box makers, generally family- or PE-owned:

• Yazoo Mills (New Oxford, PA; founded 1902) — one of the largest independent U.S. paper-tube-and-core makers; estimated ~$25–50 M revenue.[11]
• Ace Paper Tube (founded 1968) — custom cores for film/tape winding.[12]
• Dart Container/Solo — paper cups, dinnerware and food containers; describes itself as family-owned, with third-generation family members serving as owners and directors.[20]
• Novolex/Pactiv Evergreen — foodservice packaging and beverage cartons; Novolex (Apollo-affiliated) acquired Pactiv Evergreen in April 2025 for approximately $6.7 billion including net debt, though that price covered a broad multi-substrate packaging company, not a pure 322219 asset.[21]
• Mauser — fiber drums.
• Others in the tube/core/drum/rigid-box tail: Precision Paper Tube, Heartland Products Group, and numerous regional setup-box and specialty converters.[11][12]

Because the pure plays are private, the practical public-market position is: buy Sonoco or Greif and accept that you're getting a diversified packaging company where paperboard containers are a meaningful but not exclusive slice.

5. How the money works

Owners here make money on the classic manufacturing spread: conversion margin — the gap between what a shaped paperboard container sells for and the cost of the board, labor, and energy that go into it — earned across enough volume to cover fixed factory costs. The economics that actually move the needle:

• Input cost pass-through. The dominant raw material is recycled paperboard (chiefly uncoated recycled paperboard, or URB), which is itself made from recovered fiber — mainly old corrugated containers (OCC). When recovered-fiber and URB prices move, converters raise or cut product prices to protect the spread. In 2025, both Sonoco and Greif announced URB increases (~$50–70/ton) and follow-on 8%-ish increases on tubes, cores, and converted products, explicitly citing input inflation and mill utilization.[9] The ability to pass costs through — with a lag — is the single most important margin lever. Many multi-year contracts contain pass-through provisions for raw materials, energy, labor and other manufacturing costs.[18]

• Vertical integration. The big players own the recycled-paperboard mills (NAICS 322130) that feed their converting plants. That captures two margins instead of one, smooths raw-material supply, and turns recovered-fiber price swings into a partial internal hedge. It's why Sonoco and Greif are described across mills-plus-converting rather than converting alone.[5][6]

• Capacity utilization and cyclicality. These are fixed-cost factories. Running the mills and winders full earns money; running them half-empty destroys margin. Tube-and-core and fiber-drum demand tracks industrial production — paper, film, textiles, construction, chemicals — so utilization (and therefore profit) rises and falls with the broader industrial cycle. Mill closures during 2025's soft patch were a direct response to weak volumes.[9]

• Product mix. Rigid/luxury setup boxes and specialty composite cans carry higher margins than commodity cores. Consumer-facing composite cans are stickier (they're specified into a brand's packaging); commodity cores are price-competitive and cyclical.

• Freight geography. Paperboard containers are bulky and light; shipping air is expensive. Many finished products "cube out" a truck before reaching its weight limit. Plants serve regional customers, which both protects incumbents locally and caps how far anyone can profitably reach.

Segment profitability benchmarks. Sonoco's Industrial Paper Packaging segment reported 2025 operating margin of 13.6% (up from 11.6% in 2024), with favorable price/cost contributing $51 million and productivity initiatives $28 million, partly offset by a $28 million volume headwind.[5] Graphic Packaging's broader Americas Paperboard Packaging segment reported 2025 operating income of $818 million on sales of $5.89 billion; company-wide profitability weakened as lower pricing and volume combined with commodity and labor inflation.[18] Huhtamaki's North America segment reported 2025 adjusted EBIT margin of 11.6%, with sales declining 4% and adjusted EBIT falling 20% because of lower pricing and adverse currency effects despite higher volume.[19] These public results suggest that low-double-digit operating profitability is attainable for scaled, differentiated packaging platforms, but they do not establish an average margin for NAICS 322219 as a whole.

Watch, in the public filers: segment operating margin, sales volume/mix vs. price, the spread between selling prices and recovered-fiber/URB cost, and mill operating (utilization) rates.

6. What drives demand

• Industrial production — the biggest swing factor for tubes, cores, and drums. Cores are consumed wherever something is wound onto a roll (paper, film, foil, tape, textiles, wire); drums move chemicals and food ingredients. When factories slow, so does this industry.
• Consumer packaged goods — snacks, nuts, powdered beverages, coffee, refrigerated dough, nutritional powders drive composite-can demand. North America is roughly a third of the global composite-can market.[7]
• Food-away-from-home spending — USDA reports that U.S. food-away-from-home spending increased from $1.45 trillion in 2023 to $1.52 trillion in 2024, supporting nominal foodservice-packaging demand, though inflation-adjusted growth slowed to 0.4% in 2024.[22]
• Substitution — both ways. Tailwind: brands replacing rigid plastic and metal with recyclable paper composite cans on sustainability grounds; market researchers project the composite-can category growing over the next decade.[7][14] Huhtamaki reported that an increasing number of state foam-packaging bans supported demand for fiber-based packaging during 2025.[19] The Foodservice Packaging Institute's 2025 survey identified plastics-to-paper conversion, unbleached appearance, recycled content, and development of alternative-barrier technologies as key trends.[23] Headwind: some legacy lines (frozen-juice concentrate, certain metal-substitution reversals) have shrunk for years.
• Construction — concrete-forming tubes rise and fall with building activity.
• E-commerce and premiumization — direct-to-consumer shipping and "unboxing" culture support mailing tubes and luxury rigid setup boxes; the global luxury-rigid-box category is estimated in the mid-single-digit-billions and growing.[8]
• Housing/retail cyclicality — gift, cosmetics, and electronics packaging (setup boxes) tracks discretionary consumer spending.

Recyclability nuance. Sustainability is not an unqualified advantage. Barrier layers, food contamination and mixed-material closures can reduce recyclability. EPA's 2018 data put the recycling rate for all paper and paperboard packaging at 80.9%, but that result was dominated by corrugated boxes; the rate for paper containers and packaging excluding corrugated was only 20.8%.[24] Reusable cups and containers, lightweight plastics, flexible laminates, metal, glass and molded fiber can all substitute for 322219 products depending on barrier performance, cost and regulation.

---

7. Regulation

Not a heavily licensed industry, but several regimes shape products and costs:

• Food-contact safety (FDA). Every component reasonably expected to migrate into food must have an appropriate regulatory basis, with paper and paperboard components principally addressed in 21 CFR Part 176.[25] Containers touching food must meet U.S. Food and Drug Administration (FDA) food-contact material rules — relevant to composite food cans, liquid cartons, and sanitary containers.
• PFAS restrictions. Per- and polyfluoroalkyl substances (PFAS) — grease- and moisture-proofing chemistries historically used in some paper food packaging — are being phased out. FDA announced in February 2024 that PFAS-containing grease-proofing substances were no longer being sold for U.S. paper food-packaging applications; in January 2025 it determined that 35 related food-contact notifications were no longer effective.[26] Replacement barriers must still deliver grease, moisture and heat performance, so reformulation creates cost, qualification and failure risk.
• Extended producer responsibility (EPR) and recycled-content mandates. Packaging EPR laws in California, Maine, Oregon, Colorado, Minnesota and others shift end-of-life packaging costs onto producers and reward recyclable, recycled-content materials — a net positive for recycled-paperboard containers relative to hard-to-recycle plastics, but a compliance and reporting burden.
• Fiber drums for hazardous materials. Fiber drums used for hazardous materials must comply with DOT specifications under 49 CFR 178.508.[27]
• Environmental permitting. The upstream recycled-paperboard mills owned by integrated players carry air, water, and energy permitting and emissions obligations.
• Workplace safety. Paper and cardboard dust is identified in OSHA guidance as combustible cellulosic dust.[28] BLS reported a 2024 total-recordable injury rate of 2.1 cases per 100 full-time-equivalent workers for NAICS 322219.[29]

The regulatory drift — anti-plastic, pro-recyclability — is, on balance, favorable to paper-based containers. (Forward-looking.)

8. Competitive dynamics and consolidation

The federal concentration data tell a clear story for 2022: the top four firms make 53.4% of shipments, the top eight 74.2%, the top twenty 85.9%, and the top fifty 94.4% — out of 159 firms total.[3] The Herfindahl-Hirschman Index (HHI, a standard concentration gauge where higher means more concentrated) is 872, which sits in the "unconcentrated" band by antitrust convention.[3] Reconcile those two facts this way: a couple of national vertically integrated giants dominate the branded, capital-intensive lines (composite cans, drums, integrated mill-to-core), while a long, fragmented tail of regional independents competes on the commodity cores and local rigid-box work — enough small players to keep the overall index low even though the top of the market is heavily concentrated. An SBA special tabulation of 2012 Census data reported a Gini coefficient of 0.829 for this industry, consistent with substantial inequality in firm size.[30]

Consolidation is ongoing and driven by two logics: (1) integrating mills with converting to capture margin and secure fiber, and (2) portfolio focus. Sonoco spent 2024–2025 sharpening onto core packaging — acquiring the Eviosys metal-food-can business (~$3.9 B) while divesting its thermoformed & flexibles unit to TOPPAN (~$1.8 B) and other non-core assets, cutting net debt sharply.[10] Greif likewise runs an acquisitive, integration-led model. The competitive moats are scale in fiber procurement, mill integration, plant proximity to customers, and product specification lock-in — not technology.

9. Risks

• Cyclicality. Tube/core/drum volumes are levered to industrial production; a manufacturing slowdown hits utilization and margins fast, as 2025 showed.[9] Food, beverage and household packaging has consumer-staples characteristics, but foodservice formats respond to restaurant traffic and consumer budgets.
• Input-price whipsaw. Recovered-fiber (OCC) and URB prices are volatile; margin depends on passing them through with a lag, which compresses profits when costs spike or demand is too weak to price into.[9]
• Secular decline in legacy lines. Frozen-concentrate cans and some snack formats have shrunk; not every product line participates in the "paper beats plastic" tailwind.
• Substitution risk in reverse. Flexible pouches, molded fiber, reusable containers, lightweight plastics, and metal/glass can all take share from rigid composite cans and paper food containers depending on barrier performance, cost and regulation; the substitution knife cuts both ways.[24]
• Customer concentration and specification risk. Losing a large CPG account that specified a composite can, or a big winding customer, removes volume that fixed-cost plants can't easily replace. Large food, beverage and restaurant accounts can impose demanding qualification, service and sustainability requirements.
• Regulatory/compliance cost. PFAS reformulation creates cost, qualification and failure risk even as the broader trend favors paper.[26] EPR reporting raises costs.
• Workplace hazards. Combustible dust, repetitive-motion and machine-safety exposure, and union negotiations at larger plants create labor and safety risks.[28][29]
• No pure-play access. Public investors can't isolate this industry; Sonoco/Greif returns are dominated by their larger, unrelated segments and by M&A execution and leverage.

10. How to invest, and the outlook

Public routes. The primary ways in are Sonoco (SON) and Greif (GEF/GEF.B) — each roughly a $4–5 billion market-cap diversified packaging company.[13] Buy them for the composite-can / tube-core / fiber-drum franchises, but underwrite the whole company: Sonoco is now a rigid-paper-plus-metal-packaging story after the Eviosys deal and TFP divestiture[10], and Greif is a broader industrial-packaging (steel/plastic/fibre drums, IBCs, containerboard) group[6]. Both are long-standing dividend payers — Sonoco in particular has a multi-decade record of dividend increases — so the appeal skews toward income and steady, cyclical compounding rather than growth. Graphic Packaging (GPK) provides exposure to cups, bowls, canisters and food containers, though folding cartons and integrated paperboard dominate its business.[18] Huhtamaki (Nasdaq Helsinki) offers foodservice and fiber exposure through a geographically broader portfolio.[19] Reserve any judgment on share price, yield, or valuation multiple for your own diligence at time of purchase.

Private routes. This is where the pure-play exposure lives — and where most of the 159 firms are. Options: acquire or back an independent tube-and-core, fiber-drum, or rigid-setup-box converter (many are family-owned and reaching succession); roll up regional independents (the classic integration thesis the public players run); or invest in the upstream recycled-paperboard mills that supply them. Private-market economics reward local density, fiber access, and customer specification lock-in. The key underwriting items are revenue by actual product rather than company SIC code, customer concentration, freight radius, board-index pass-through provisions, line utilization, waste and setup time, maintenance capital, food-contact qualifications, barrier technology and local recycling/EPR treatment. Vertically integrated assets need mill economics separated from conversion economics.

Near-term drivers to watch (forward-looking). (1) The industrial cycle and mill utilization — the swing factor for tubes, cores, and drums.[9] (2) Recovered-fiber and URB prices and how cleanly converters pass them through.[9] (3) The sustainability substitution trend — paper composite cans displacing plastic/metal — which market forecasters expect to keep the composite-can category growing.[7][14] (4) EPR and PFAS rollout, a modest tailwind for recyclable paper containers and a compliance cost.[26] (5) Continued consolidation and portfolio moves by Sonoco and Greif, which will matter more to the stocks than organic 322219 demand.[10]

Bottom line. A mature, consolidated, cyclical ~$9 billion U.S. converting niche with no pure public play. Public investors get diversified, dividend-oriented exposure via Sonoco, Greif, or (with less direct relevance) Graphic Packaging and Huhtamaki; private investors get the actual pure plays in a fragmented, succession-heavy long tail. The secular sustainability shift is a real but uneven tailwind — strongest in consumer composite cans and foodservice containers, absent in the commodity and legacy lines.
