PFAS in Packaging: What Consumer Products Companies Need to Know
PFAS Has Become a Packaging Compliance Issue
Packaging is often evaluated by what can be seen and measured relatively easily. A company can determine the weight of a bottle, identify the resin used to manufacture it, calculate the percentage of recycled content it contains, or record the amount of corrugated material used to ship it. Increasingly, however, packaging compliance also requires companies to understand characteristics that are far less visible.
Per- and polyfluoroalkyl substances, commonly known as PFAS, are a good example. PFAS are a broad family of synthetic fluorinated substances that have been used across numerous industrial and consumer applications because certain PFAS provide useful resistance to grease, oil, water, heat, and moisture. Those properties made them particularly valuable in applications where materials needed to create a durable barrier between a product and the outside environment. At the same time, the chemical stability that makes many PFAS useful also contributes to their persistence in the environment, which has driven growing regulatory attention in the United States and internationally.
For consumer products companies, that regulatory attention has created a new kind of packaging compliance problem. A company may purchase what appears to be an ordinary paper food container, wrapper, carton, or other packaging component from a supplier. The package may perform exactly as intended and look no different from a comparable package used years earlier. Yet the chemistry of a coating or treatment applied somewhere upstream in the supply chain can now determine whether that package may legally be placed on the market in a particular jurisdiction.
At first, the compliance question appears simple: Does our packaging contain PFAS?
In practice, answering that question can require considerably more information. Which substances are included within the applicable definition of PFAS? Were they intentionally added? Does the regulation prohibit intentional addition, establish a concentration threshold, or both? Which packaging materials and product categories are covered? What information has the supplier provided? Does that information cover the entire component or only one material within it? Has the component changed since the documentation was issued? And, perhaps most importantly, does the answer satisfy the particular regulation applicable in the jurisdiction where the product is being sold?
PFAS regulation therefore illustrates a recurring reality of modern packaging compliance: understanding the law is only the beginning. Companies also need reliable information about the physical packaging to which the law applies.
Understanding What PFAS Actually Means
One reason PFAS compliance can become complicated so quickly is that PFAS is not the name of a single chemical. It describes a large family of fluorinated substances.
Some individual PFAS, including PFOA and PFOS, have become relatively well known because of the regulatory and public attention surrounding them. But a declaration stating that a material does not contain PFOA or PFOS does not necessarily establish that the material contains no PFAS relevant to another regulatory requirement. The broader category encompasses many substances, and the precise definition of what qualifies as PFAS can vary depending upon the regulatory framework being applied. EPA itself notes that different regulatory programs can use different PFAS definitions.
That distinction matters operationally.
Imagine that a packaging supplier sends a CPG company a document stating that a paperboard container is "PFOA- and PFOS-free." An employee unfamiliar with the distinction could reasonably enter "PFAS-free" into the company's packaging database. Months later, the company evaluates the package against a regulation addressing a broader category of PFAS. The original supplier statement may no longer be sufficient to support the conclusion stored in the database.
The problem is not necessarily that the supplier provided incorrect information. The problem is that the company converted a narrow statement into a broader conclusion.
This is why terms such as PFAS-free can be more complicated from a compliance perspective than they appear. The useful question is not simply whether a document contains those words. It is what the supplier actually represented, which substances were considered, what material or component the statement covers, and whether that evidence answers the regulatory question the company is trying to resolve.
Why PFAS Have Been Used in Packaging
Understanding why PFAS became a packaging issue requires understanding the performance demands placed on packaging itself.
Consider a paper wrapper surrounding a greasy food product. Ordinary untreated paper readily absorbs oils and moisture. Once that happens, the material can weaken, stain, or allow grease to migrate through the package. A barrier treatment can dramatically improve the performance of the paper while allowing manufacturers to retain the lightweight and inexpensive characteristics that make fiber-based packaging attractive.
Certain PFAS historically offered useful oil- and water-resistant properties for precisely these kinds of applications. Washington's Department of Ecology, for example, identified the use of intentionally added PFAS to provide oil and water resistance in plant-fiber-based food packaging as part of its evaluation of safer alternatives.
From a packaging engineering perspective, their historical use therefore makes sense. The chemical treatment performed a function.
That context is important because regulatory changes affecting PFAS are not occurring independently from packaging design. A company or supplier that removes a fluorinated treatment may still need the package to resist grease, protect the product, survive distribution, maintain shelf life, and satisfy food-contact or other product-safety requirements. An alternative coating or material therefore needs to satisfy both the new chemical restriction and the original performance requirements.
This creates a dynamic that appears repeatedly throughout packaging compliance. A change intended to solve one regulatory problem can affect several other characteristics of the package. Changing a coating may alter recyclability. Changing the substrate may alter packaging weight and therefore EPR reporting or fees. Introducing a new material may require new food-contact documentation. A supplier change may invalidate documentation previously used to support other compliance determinations.
PFAS regulation is therefore not simply a question about chemistry. It is another example of why packaging compliance increasingly intersects with engineering, procurement, sustainability, supplier management, and regulatory operations.
PFAS Packaging Regulations Are Fragmented
The regulatory challenge becomes more difficult because companies do not operate under one universal PFAS-in-packaging standard.
Different jurisdictions have adopted different approaches, covering different packaging categories and using different regulatory mechanisms. A company selling the same product in several markets may therefore need to evaluate the same packaging against several different sets of rules.
California provides one example. State law restricts PFAS in certain plant-fiber-based food packaging. The restriction addresses intentionally added PFAS while also establishing a threshold based on total organic fluorine. Importantly, the law does not simply prohibit "PFAS in packaging" as a universal category. Its scope depends on the type of packaging and the criteria established by the statute.
Washington illustrates another approach. The state has phased in restrictions on intentionally added PFAS for specified categories of food packaging. Initial categories became subject to the restriction in 2023, with additional categories following in 2024. Washington also requires manufacturers of covered food packaging to maintain certificates of compliance, turning the restriction into both a chemical requirement and a documentation obligation.
The European Union adds another regulatory framework. Under the Packaging and Packaging Waste Regulation, food-contact packaging is subject to PFAS concentration limits beginning August 12, 2026. The PPWR establishes multiple thresholds addressing individual PFAS, the sum of PFAS measured through targeted analysis, and fluorine under specified conditions.
The important lesson for a CPG company is not simply that California, Washington, and the European Union regulate PFAS. It is that they demonstrate why a single corporate rule such as "our packaging must be PFAS-free" may be insufficient as a compliance system.
The more useful question is considerably more specific:
Does this particular packaging component satisfy the PFAS requirements applicable to it in every jurisdiction where the associated product is being placed on the market?
Answering that question requires both regulatory information and packaging information.
Intentional Addition and Measured Concentration Are Not the Same Thing
One of the most important concepts for companies managing PFAS restrictions is the distinction between how a substance entered the material and how much of that substance is present.
An intentional-addition restriction is fundamentally concerned with formulation and purpose. If a PFAS substance was deliberately incorporated into a coating because it provides grease resistance, for example, the fact that it was intentionally used can be relevant regardless of whether the resulting concentration is particularly high.
A concentration-based requirement asks a different question. Rather than focusing solely on why the substance is present, it establishes a measurable limit and evaluates whether the material exceeds it.
California demonstrates why the distinction matters. For covered plant-fiber-based food packaging, the state's restriction addresses intentionally added PFAS while also using a total-organic-fluorine threshold intended to address the presence of PFAS in the material. The EU's PPWR similarly establishes specific concentration limits for PFAS in food-contact packaging rather than relying exclusively on the concept of intentional addition.
From an operational perspective, these approaches require different kinds of evidence.
A supplier declaration may help answer whether PFAS were intentionally incorporated into a material. Analytical testing may provide information about measurable concentrations. A formulation statement, certificate, specification, or test report may each answer a slightly different compliance question.
This is why a packaging database containing a single field labeled "PFAS: Yes/No" can quickly become inadequate.
A company may need to know whether PFAS were intentionally added, what evidence supports that conclusion, whether testing was performed, what was tested, what analytical method was used, what result was obtained, when the documentation was issued, and which regulatory requirement the evidence was intended to address.
The binary answer may ultimately be useful. But the evidence behind that answer is what makes it defensible.
For Most CPG Companies, PFAS Compliance Begins With Suppliers
Most consumer products companies do not manufacture every layer of their packaging.
A brand may purchase a finished food container from one supplier, labels from another, corrugated cases from another, and flexible films from yet another. The finished packaging suppliers may themselves purchase paperboard, polymers, coatings, inks, adhesives, or chemical treatments from companies farther upstream.
As a result, the company responsible for placing the finished consumer product on the market may be several steps removed from the organization that actually knows how a particular packaging material was formulated.
Consider a seemingly simple paper food container. The CPG company purchases the finished container from a converter. The converter purchases coated paperboard from a material supplier. The material supplier may rely on a coating formulation sourced from another manufacturer. Information about the chemistry relevant to PFAS compliance may therefore originate several tiers above the company whose name ultimately appears on the consumer product.
The compliance information must travel downstream even though the physical package travels in the opposite direction.
That makes supplier communication and documentation central to PFAS compliance.
A CPG company may request declarations regarding intentionally added PFAS, certificates of compliance, technical specifications, statements covering coatings or treatments, or analytical test results where appropriate. The precise evidence needed depends upon the packaging and regulatory requirement involved, but the underlying operational challenge remains consistent: the company must obtain reliable information from the organizations that know how the packaging was manufactured.
This is also why PFAS regulation connects so closely to the broader issue of supplier documentation. A company can understand every PFAS restriction applicable to its markets and still struggle to demonstrate compliance if it cannot obtain adequate information about the materials it actually purchases.
Collecting Documents Is Not the Same as Managing Compliance Evidence
Obtaining a supplier declaration is an important step, but it is not the end of the process.
Suppose a packaging supplier emails a one-page declaration stating that its product contains no intentionally added PFAS. Someone at the CPG company downloads the PDF and saves it in a folder labeled "Supplier Compliance."
The document has been retained, but several questions remain unanswered.
Which exact component does it cover? Does it correspond to a supplier part number? Does it cover the entire finished component or only the base substrate? Are coatings, inks, adhesives, and treatments included? Does the declaration apply to all manufacturing facilities supplying the component? Which version of the specification was evaluated? When did the declaration become effective? Has the supplier changed the formulation since it was issued?
If the company cannot answer those questions, it may possess the document without possessing usable compliance evidence.
A stronger system connects the declaration to the physical packaging it supports. The relationship begins with the supplier, but continues through the supplier part number, component, material, specification, compliance determination, supporting document, and effective dates.
This distinction becomes especially important as product portfolios grow. A company with ten products may be able to rely on employee knowledge and manually organized folders. A company with hundreds of SKUs, multiple suppliers, alternate components, and sales across numerous jurisdictions faces a very different problem. The compliance team needs to know not merely whether a PFAS declaration exists somewhere, but which products and packaging configurations that declaration supports.
Washington's requirements provide a useful real-world illustration. Manufacturers of covered food packaging must maintain certificates of compliance while the packaging is in use and for three years after its last sale or distribution, and those certificates must be made available upon request.
The regulatory expectation therefore extends beyond achieving a compliant formulation. The company must also be able to maintain and retrieve evidence supporting that compliance.
Packaging Changes Can Quietly Change Compliance Status
Another challenge is that packaging is not static.
Suppliers reformulate materials. Manufacturing facilities change. Alternate suppliers are approved. Coatings are replaced. Adhesives change. Packaging is lightweighted. Components are redesigned. Procurement teams identify lower-cost alternatives. Sustainability teams request different substrates. Supply disruptions force temporary substitutions.
Many of these changes may be nearly invisible to the consumer.
Imagine that a CPG company has used the same paper food container for several years. The package has the same dimensions, appearance, graphics, and supplier name. The supplier provided a PFAS declaration when the component was originally approved, and the document remains in the company's compliance records.
Two years later, the supplier changes the barrier coating.
Does the original declaration still support the current package?
Perhaps it does. Perhaps it does not. The problem is that without specification control, effective dates, supplier change notifications, and a connection between the documentation and the version of the component actually being purchased, the CPG company may have no reliable way to know.
This is where packaging compliance begins to resemble configuration management.
The question is not merely "Do we have a PFAS declaration for this component?"
It becomes:
"Do we have appropriate PFAS documentation supporting the version of this component that was actually used in products sold during the relevant period?"
That is a much more demanding standard, but it is also a much more useful way to think about compliance records.
PFAS Regulation Extends Beyond Food Packaging
Food packaging is one of the most visible areas of PFAS regulation, but companies should be careful not to assume that PFAS compliance begins and ends there.
States are increasingly regulating PFAS across broader categories of consumer products. Washington, for example, has developed PFAS restrictions and reporting requirements affecting certain consumer-product categories beyond its food-packaging law. Federal PFAS reporting and recordkeeping requirements also exist under the Toxic Substances Control Act for covered manufacturers and importers.
This matters for companies whose products and packaging may both fall within the scope of chemical regulations.
A cosmetics company, outdoor-products manufacturer, household-goods company, or other consumer brand may need to evaluate PFAS questions relating to the product itself while separately considering restrictions applicable to its packaging. The responsible suppliers, supporting documentation, regulatory definitions, and applicable deadlines may differ between the two.
The result is another layer of regulatory fragmentation. A company cannot necessarily answer the question "Are we compliant with PFAS regulations?" at the company level. Compliance may depend on the particular product, packaging component, material, jurisdiction, and date being evaluated.
What PFAS Compliance Data Actually Looks Like
Once the regulatory concepts are translated into day-to-day operations, PFAS compliance becomes a data-management exercise.
A company first needs to know what packaging it actually uses. That means connecting individual SKUs to bottles, cartons, wrappers, labels, closures, films, inserts, and other relevant components. Those components need to be connected to suppliers and supplier part numbers. Material information may need to identify substrates, coatings, treatments, or other characteristics relevant to the applicable requirement.
PFAS information can then be attached to those underlying packaging records.
A company might record whether a supplier has represented that PFAS are intentionally added, what basis supports that representation, whether analytical testing has been performed, what documentation exists, when that documentation was issued, and which component specification it covers. Effective dates allow the company to preserve historical information when components or formulations change.
Jurisdictional information adds the final regulatory layer. The company can evaluate which PFAS restrictions apply based on where products are sold and determine whether the evidence maintained for each relevant component is sufficient to address those requirements.
The resulting information structure might conceptually connect:
Product → Packaging Component → Material → Supplier → Specification → PFAS Information → Supporting Evidence → Effective Period → Jurisdiction
The important feature is not the precise number of spreadsheet columns. It is the relationship between the information.
A supplier declaration without a component relationship is difficult to use. A component without a supplier relationship makes updates difficult to manage. A PFAS determination without supporting evidence is difficult to substantiate. A compliant component without jurisdictional sales information does not tell the company where the determination matters.
Each individual data point has limited value until it is connected to the others.
PFAS Demonstrates Why Packaging Compliance Cannot Be Managed Regulation by Regulation
Consider a single packaged food product.
The company may need to know the weight and material composition of its packaging to satisfy EPR reporting requirements and calculate producer-responsibility fees. It may need to know the percentage of post-consumer recycled resin used in a plastic component to evaluate recycled-content requirements. It may need supplier declarations or analytical information concerning a coating to evaluate PFAS restrictions. It may need separate technical information establishing that materials contacting the food are suitable for their intended use. Marketing may also want documentation supporting environmental claims printed on the package.
Every one of those questions concerns the same physical packaging system.
Yet companies often approach them as separate compliance projects. One spreadsheet is created for EPR. Another is created for recycled content. PFAS declarations are stored in a shared folder. Food-contact documentation is maintained by quality assurance. Packaging specifications live with engineering or procurement. Sales data exists somewhere else entirely.
That structure may function when regulatory obligations are limited. It becomes increasingly difficult to maintain as more jurisdictions adopt packaging requirements.
A change to a single bottle can affect its weight, material composition, recycled-content percentage, supplier documentation, EPR reporting, and perhaps its compliance status under another material restriction. If every regulatory workstream maintains a separate version of the packaging record, each change creates an opportunity for those records to diverge.
A more scalable approach begins with the packaging itself.
The company maintains reliable information describing what the package is made from, what each component weighs, who supplies it, which specifications and documents support it, which products use it, when those relationships were effective, and where those products are sold. Regulations can then be mapped against that common foundation.
Under that model, PFAS does not require the company to build an entirely new compliance dataset.
It becomes another question that can be asked of an existing packaging information system.
The Real Challenge Is Knowing What You Can Prove
PFAS regulation highlights an important distinction between believing a package is compliant and maintaining enough information to demonstrate why that belief is reasonable.
A procurement employee may have been told by a supplier that a coating is PFAS-free. A packaging engineer may know that the company stopped specifying fluorinated treatments years ago. A supplier may have confirmed compliance during a phone call. All of those things can contribute to confidence, but they are difficult to operationalize across a large product portfolio or reproduce years later when someone asks for evidence.
Modern packaging compliance increasingly requires institutional knowledge to become structured information.
That means identifying the package, identifying the supplier, documenting the relevant material characteristics, retaining supporting evidence, recording when the information applies, and maintaining those relationships as the package changes.
PFAS makes this particularly visible because the characteristic being regulated often cannot be determined simply by looking at the package. The answer lives somewhere in the supply chain.
The company's challenge is making sure that information reaches the organization, remains connected to the correct packaging component, and can be retrieved when it matters.
Where Cedarline Fits
PFAS compliance depends on more than knowing that a restriction exists. Companies need to understand which packaging components may be affected, what materials and treatments those components contain, who supplies them, what declarations or test results support their compliance status, which versions of those components are currently being used, and where the resulting products are sold.
Organizing those relationships creates value beyond any single PFAS requirement.
The same component weights and material classifications can support EPR reporting. Supplier records can support recycled-content determinations. Specifications and effective dates can help manage packaging changes. Sales information can establish jurisdictional applicability. Supporting documentation can provide evidence for several different regulatory questions.
This is increasingly what packaging compliance looks like for consumer products companies. The regulations may originate from different governments, address different environmental concerns, and require different calculations or documentation. But again and again, they depend on the same underlying information about the company's products, packaging, suppliers, and markets.
PFAS is another example of why the difficult part of packaging compliance is often not finding the regulation. It is maintaining the information necessary to apply that regulation across a changing product portfolio and supply chain.
The regulation asks the compliance question. The packaging data and supplier documentation provide the answer.
