Is your folding carton supplier limiting your paperboard sourcing options?
Netpak sources paperboard across multiple qualified suppliers and operates independently from any single mill. Canadian and U.S. brands gain more sourcing options when board pricing, availability, specifications or lead times change.
Find out whether your current carton program has more sourcing options.
Send Netpak the current board grade, caliper, dieline or carton dimensions, annual volume and delivery requirements. Netpak can review the specification against its paperboard supplier network and manufacturing capabilities before you make a supplier decision.
How much flexibility exists behind your current folding carton supply?
The converter on the purchase order represents only one part of the supply chain. Paperboard availability, mill capacity and upstream procurement determine how many options remain when conditions change.
Where does your converter source the paperboard?
A converter concentrated around one mill system may have fewer upstream alternatives available for the same carton specification.
Can another qualified board source be compared after a price increase?
Procurement flexibility improves when technically acceptable material can be evaluated across more than one upstream supplier.
What happens when lead time stretches?
Alternate sourcing paths can help prevent paperboard timing from becoming the limiting factor in the carton production schedule.
Which alternate boards already fit the technical requirements?
Useful alternatives still need to satisfy caliper, stiffness, printing, converting and certification requirements.
Does the supply plan include inventory?
Board stocking, finished-carton inventory and scheduled releases can reduce exposure to individual production windows.
Can you benchmark another converter before moving production?
Supplier qualification can begin while the incumbent program continues running.
What the 2025-2026 North American paperboard market demonstrated
Paperboard conditions vary by grade. During 2025 and 2026, North American buyers encountered producer price actions, mill closures, production reductions and substantially different operating rates across boxboard categories. Those events show how quickly the sourcing environment behind a folding carton program can change.
Several paperboard producers announced 2026 price increases of 4% to 6% on SBS, FBB and related boxboard products in the Americas.1
Q2 2026 operating rate for uncoated recycled boxboard reported by AF&PA.2
Projected reduction in Canadian cartonboard capacity tied to a major 2026 mill closure.3
Tons of annual SBS capacity associated with a Quebec paper machine permanently closed in 2026.4
Cartonboard costs grew faster than folding carton prices during the preceding decade
Fastmarkets RISI reported average annual cartonboard cost growth of 4.4% from 2014 through 2024, compared with 3.0% annual growth in folding carton prices. Its North American outlook identifies the gap as a continuing margin challenge for independent converters.3 A converter’s paperboard procurement strategy can therefore affect competitiveness even during periods of adequate overall supply.
Packaging Dive reported in July 2026 that SBS remained oversupplied while several producers announced 4% to 6% increases on SBS or FBB products and continued to rationalize capacity.1 Excess supply at the industry level did not prevent individual producers from changing pricing or production.
AF&PA reported an overall U.S. boxboard operating rate of 88.8% in Q2 2026. Unbleached kraft and coated recycled boxboard operated at 92.6%, while uncoated recycled boxboard reached 97.2%. Solid bleached boxboard production increased 4% compared with Q2 2025.2 The required substrate can therefore place one carton program in a different supply environment from another.
Fastmarkets RISI projected that a major Canadian cartonboard mill closure in 2026 would reduce national capacity by roughly 24% and tighten supply. Its public summary also noted that independent converters could experience less exposure because of the closing mill’s integration structure.3
North American paperboard production has been shifting into fewer assets
Mill closures, machine shutdowns and production consolidation during 2025 and 2026 changed the location and ownership of available paperboard capacity.
Recycled paperboard production consolidated after U.S. and Canadian closures
A major North American integrated paperboard producer disclosed closures of recycled-paperboard facilities in Ohio and Quebec during 2025 as production was consolidated into fewer manufacturing locations.5
A Quebec SBS machine with 127,000 tons of annual capacity closed
The producer permanently closed the La Tuque paper machine after citing its scale and cost position. The machine represented 127,000 tons of annual solid bleached sulfate capacity.4
Arkansas SBS production was reduced to roughly half of capability
A North American SBS producer announced that its Cypress Bend, Arkansas facility would operate at approximately half of production capability as the company responded to a supply-driven industry downturn.6
SBS and FBB price actions arrived during continued SBS oversupply
Several producers announced increases on SBS, FBB or related boxboard grades in the Americas while industry reporting continued to characterize SBS supply as excessive.1
Paperboard supply conditions vary materially by grade
U.S. Bureau of Labor Statistics data for June 2026 showed the producer-price index for noncorrugated paperboard slightly below its June 2025 level.7 During the same period, AF&PA reported a 97.2% operating rate for uncoated recycled boxboard, while industry reporting continued to describe SBS as oversupplied.2
Procurement teams therefore need to evaluate the substrate behind each carton program individually. SBS, CRB, FBB and other grades can face different pricing, capacity and availability conditions at the same time.
Netpak’s mill-independent procurement model is designed around that flexibility.
Independent multi-mill sourcing and mill-integrated sourcing create different procurement options
Vertically integrated converters can benefit from direct access to their own mill networks. Independent converters can build procurement around outside suppliers and compare qualified material across a broader upstream market. Buyers should understand which model supports their carton program when price, availability or timing changes.
Integrated folding carton networks can source heavily from their own paperboard mills
One major North American integrated paperboard and packaging producer reports that it manufactures most of the paperboard consumed by its Americas operations.5 Another major vertically integrated producer reports that substantially all of its converting operations’ containerboard and paperboard requirements are supplied through its own mills and trade swaps.8 These disclosures illustrate how deeply upstream paperboard production can be connected to downstream converting inside an integrated network.
Supplier structure affects the alternatives available to procurement.
Integrated producers can offer direct control over their mill networks. Netpak’s independent procurement model allows qualified paperboard to be evaluated across multiple outside suppliers.
The carton specification drives the paperboard decision
Paperboard affects carton cost before printing begins. It also influences stiffness, surface quality, print performance, die cutting, folding, gluing, certification requirements and production timing.
Netpak operates as an independent folding carton manufacturer with paperboard sourcing relationships across multiple suppliers. Procurement can evaluate material options according to the technical and commercial requirements of each packaging program.
Multiple qualified sourcing paths give Netpak additional options when board pricing, availability or lead times change. The carton specification continues to define which materials are acceptable.
Alternate paperboard still requires technical qualification.
Caliper, stiffness, surface characteristics, print performance, converting behavior and applicable certification requirements remain part of the material review.
Multi-sourcing reduces dependence on one upstream supplier
NIST’s Manufacturing Extension Partnership advises manufacturers to develop relationships with multiple suppliers as part of supply-chain resilience planning. Multiple sourcing relationships can reduce dependence on a single source and improve a manufacturer’s ability to respond to disruption.9
Folding carton paperboard adds technical constraints to that strategy. Available material still has to perform correctly through printing, die cutting, folding and gluing while meeting structural, visual and certification requirements.
Netpak combines upstream supplier choice with folding carton manufacturing expertise. Procurement can examine alternate sourcing paths without treating paperboard as an interchangeable commodity.

Sourcing flexibility starts with a technically appropriate substrate
Netpak’s paperboard offering for folding cartons includes SBS, SUS, CRB, FBB, URB and micro-flute options. Material selection should reflect carton structure, printing requirements, product needs and converting conditions.
SBS paperboard
Solid bleached sulfate is commonly considered for cartons that require a bright white print surface, detailed graphics and clean product presentation.
CRB paperboard
Coated recycled board can fit programs where recycled fiber content, retail performance and carton economics are important considerations.
FBB paperboard
Folding boxboard can provide useful stiffness-to-weight performance for appropriate retail and consumer folding carton applications.
Material economics have to survive the converting process.
Paperboard cost should be evaluated alongside structural performance, printing, die cutting, folding and gluing. A lower material price provides little benefit if the substrate creates production or quality problems.
Inventory planning adds another layer of supply control
Paperboard sourcing determines whether material can reach production. Inventory planning determines how much timing flexibility exists after material or finished cartons are available.
Netpak’s warehousing and logistics services support folding carton inventory programs, scheduled releases and just-in-time delivery.
Repeat programs can be planned around order cadence, forecast reliability, stock requirements and delivery timing instead of relying exclusively on the next purchase order and production window.

Questions procurement teams ask when evaluating folding carton supply
Why does multi-mill paperboard sourcing matter for folding cartons?
Multiple qualified sourcing relationships give a converter more options when an individual paperboard supplier changes pricing, availability or timing. Any alternate material still needs to meet the technical requirements of the carton.
Is there a North American paperboard shortage?
Supply conditions vary by grade and production asset. During 2025 and 2026, SBS remained oversupplied while some recycled boxboard grades operated at much higher utilization, producers removed or consolidated capacity, and several suppliers announced price increases. Procurement should evaluate the specific grade and production window required for each carton program.
Which paperboard grades can Netpak source?
Netpak’s paperboard offering includes SBS, SUS, CRB, FBB, URB and micro-flute options. The appropriate substrate depends on carton structure, print requirements, product needs, finishing and production conditions.
Can Netpak substitute another board without technical review?
Alternate sourcing still requires material qualification. Caliper, stiffness, print performance, converting behavior, certification requirements and other technical criteria need to remain compatible with the carton program.
Do I need to leave my current folding carton supplier before Netpak reviews the program?
Supplier benchmarking can take place while the incumbent program remains active. The review establishes whether Netpak represents a credible alternative before procurement makes a transfer decision.
Can Netpak be qualified as a second folding carton source?
Procurement can evaluate Netpak as an additional qualified source for one program or SKU. A second source can provide another option for capacity, new programs, price comparisons and supply disruption.
Can U.S. companies source folding cartons from Netpak in Canada?
Netpak supports Canadian-made folding carton programs for U.S. brands. U.S. buyers can evaluate the program using total landed cost, freight, customs requirements, delivery timing, inventory strategy, quality requirements and the carton specification.
What information does Netpak need to benchmark an existing carton?
Useful inputs include board grade, caliper, carton dimensions or dieline, order quantities, annual usage, print and finishing requirements, certifications, delivery destinations, inventory needs and current lead time.
