Phthalates in food packaging are receiving renewed regulatory attention as the US Food and Drug Administration (FDA) advances its review of chemicals used in materials that come into contact with food. On May 27, 2026, the agency published a scientific evaluation examining whether certain phthalates should be grouped for a future cumulative risk assessment. The findings matter to packaging manufacturers, food processors, chemical traders and procurement teams that source materials for food-contact applications.
Phthalates serve an important industrial purpose by making certain plastics softer and more flexible. However, their suitability for food-contact applications depends on the specific substance, its intended use, potential migration into food and the regulatory requirements that apply to the finished material. Buyers therefore need to evaluate more than a supplier's product description when assessing packaging safety.
What Are Phthalates and Why Does the Packaging Industry Use Them?
Phthalates are a group of chemical compounds commonly used as plasticizers. Manufacturers add plasticizers to certain polymers, particularly polyvinyl chloride (PVC), to improve flexibility, reduce brittleness and support processing.
Rigid plastic materials can be difficult to adapt to applications that require bending, sealing or repeated movement. A suitable plasticizer can change these physical properties, allowing manufacturers to produce flexible components for a range of industrial uses.
Historically, certain phthalates have appeared in food-contact applications and related materials, including components of adhesives, lubricants and sealants. Their presence in a material does not automatically mean that the material poses an unacceptable risk. The specific chemical, concentration, application and potential exposure all matter.
For food packaging manufacturers, plasticizer selection involves balancing several technical requirements:
Flexibility and durability: The packaging must withstand its intended handling and storage conditions without cracking or losing performance.
Processing compatibility: Additives must suit the polymer formulation and the manufacturing process.
Food-contact suitability: The substance and its intended conditions of use must meet applicable regulatory requirements.
Exposure management: Manufacturers need to understand whether a substance could migrate from packaging into food and whether that exposure remains within the relevant safety assessment.
These considerations make chemical selection an important part of packaging design rather than simply a decision about material cost.
What the FDA's May 2026 Evaluation Means
The FDA's May 2026 evaluation examined eight phthalates that remained authorized as plasticizers for specified food-contact uses in the United States. The agency assessed scientific literature to determine whether these substances should be considered chemically or pharmacologically related for a future cumulative risk assessment.
The evaluation supported grouping four substances for further assessment:
Di(2-ethylhexyl) phthalate (DEHP)
Dicyclohexyl phthalate (DCHP)
Diisooctyl phthalate (DIOP)
Diisononyl phthalate (DINP)
The agency considered chemical structures, physicochemical properties and information about how these substances behave in the body. Grouping related substances can help regulators examine whether combined exposure deserves assessment rather than evaluating every chemical entirely in isolation.
This development does not mean that every phthalate has the same properties or that the evaluation itself automatically prohibits the four substances. Instead, it establishes a scientific basis for considering a particular group in a future cumulative assessment.
The FDA's work forms part of a broader effort to revisit the safety of food-contact chemicals as new information becomes available. For businesses, the practical message is to track the status of individual substances and their authorized uses instead of treating all phthalates as interchangeable.
How Chemical Exposure and Migration Affect Food Safety
A central question in food packaging safety is whether chemicals can migrate from a packaging material into the food it contacts. Migration depends on several factors, including the chemical's properties, the composition of the packaging, the type of food and the conditions under which the product is used.
For example, temperature, contact duration and the nature of the food can influence the assessment of a packaging material. A substance used in a component that does not directly contact food may present a different exposure scenario from one incorporated into a layer that touches the product.
Regulators use exposure estimates and toxicological evidence to understand potential consumer exposure. These assessments help determine whether an authorized use remains consistent with applicable safety requirements.
For packaging manufacturers and procurement teams, the main considerations include:
Intended food type: Confirm that the material is suitable for the food category involved, particularly when its composition could affect migration.
Temperature and contact duration: Check whether the material's authorization covers the intended filling, processing, storage and distribution conditions.
Material composition: Understand which additives, plasticizers and other substances form part of the finished packaging.
Potential migration: Review relevant testing or supporting evidence where required by the applicable regulatory framework.
A general statement that a material is suitable for packaging does not necessarily establish its suitability for every food-contact application. Buyers should match the supplier's documentation to the precise use they intend to make of the product.
Regulatory Changes and the Remaining Authorized Uses
The FDA has already taken significant steps to narrow the range of phthalates permitted for food-contact applications in the United States. In May 2022, the agency revoked authorizations for the food-contact uses of 23 phthalates and two other substances after industry demonstrated that those uses had been abandoned. The action left nine phthalates authorized for specified food-contact applications, including eight used as plasticizers and one used as a monomer.
The agency subsequently continued reviewing the remaining authorized uses. Its 2026 evaluation represents another stage in this process, with a focus on scientific relationships among substances and the potential for a future cumulative risk assessment.
Three distinctions are particularly important for companies trading or purchasing packaging materials:
Authorization is use-specific: A substance's authorization does not establish that it is suitable for every polymer, food category or operating condition.
Regulatory status can change: A material that meets current requirements must still be monitored against relevant updates in the markets where it will be sold.
Different jurisdictions have different rules: FDA requirements apply to the relevant US market. Companies selling into other countries must also assess the regulations applicable to those destinations.
The FDA's evaluation should therefore encourage stronger documentation and regulatory monitoring throughout the supply chain. It should not be interpreted as a blanket approval or prohibition covering every chemical in the phthalate family.
What Food Packaging Buyers Should Check Before Sourcing
Chemical traders and procurement managers often work through multiple suppliers, converters and distributors before a packaging material reaches a food manufacturer. Each additional stage can make it harder to confirm the exact composition of a product unless the supply chain maintains clear documentation.
Buyers can reduce uncertainty by establishing a consistent review process before approving a supplier or material.
1. Identify the exact material and intended application.
Request the polymer type, relevant additive information and intended food-contact use. Where a formulation contains plasticizers, establish the specific chemical identity instead of relying on broad descriptions such as flexible PVC or food-grade plastic.
2. Request appropriate compliance documentation.
Ask suppliers for applicable declarations, technical data and supporting evidence for the target market. Confirm that any stated compliance applies to the actual material, its composition and the intended conditions of use.
3. Review testing requirements.
Determine whether migration testing or other analytical evidence is required for the application. Review the test conditions and results against the intended food type, temperature and duration of contact rather than treating a generic laboratory report as universal proof of compliance.
4. Check traceability and change control.
Maintain records connecting each shipment to its supplier, product specification and relevant documentation. Ask suppliers to notify buyers when they change a formulation, manufacturing site or source of a critical additive.
5. Evaluate alternatives carefully.
If a customer requests phthalate-free packaging, confirm what the claim means for the actual product. A substitute plasticizer should also meet the required technical performance and applicable food-contact rules.
These steps help procurement teams make decisions based on the actual use of a material rather than price or marketing claims alone.
How the Review Could Affect Chemical Traders and Packaging Suppliers
Regulatory scrutiny can influence commercial decisions even before a regulator changes an authorization. Packaging manufacturers may review formulations, customers may request additional documentation and distributors may need to improve their ability to identify the chemical composition of products they sell.
For traders, these developments create several practical priorities.
First, product information becomes a competitive advantage. Suppliers that provide clear specifications, consistent batch records and relevant compliance documentation can help buyers shorten approval processes and reduce uncertainty.
Second, customers may ask for alternatives to particular plasticizers. These requests can create opportunities for suppliers of alternative materials, but substitution requires technical assessment. A different chemical may behave differently during processing or may have its own restrictions.
Third, international trade requires careful attention to destination markets. A product accepted for one application in the United States may not automatically satisfy requirements in Europe, Asia or another export destination. Importers and exporters should establish the regulatory scope of each transaction before confirming supply.
Finally, companies should consider the full cost of a material. A lower purchase price may offer limited value if incomplete documentation causes delays, additional testing or rejection by a downstream customer.
Why Material Substitution Requires More Than a Phthalate-Free Claim
Reducing reliance on a particular plasticizer may appear straightforward, but packaging formulations involve several interacting properties. A replacement must deliver the required flexibility, durability, processing performance and compatibility with the intended food-contact conditions.
Alternative plasticizers may differ in their migration behaviour, stability and effectiveness at a given concentration. Manufacturers should therefore evaluate the finished formulation rather than assume that removing one chemical automatically makes a product suitable for every application.
Procurement teams should also distinguish between a chemical-level claim and a finished-product compliance claim. A supplier may confirm that a particular phthalate is absent, but that information alone does not demonstrate that every component of the packaging meets all applicable requirements.
A sound substitution programme should include:
Technical assessment of the replacement material under the intended manufacturing conditions.
Evaluation of food-contact suitability under relevant regulations.
Appropriate testing and documentation for the finished packaging.
Confirmation that changes do not compromise sealing, durability or product protection.
For traders, offering documented alternatives can help meet customer needs while maintaining a clear distinction between technical performance and regulatory compliance.
What Procurement Teams Should Do Next
The FDA's May 2026 evaluation reinforces the importance of substance-specific safety assessments and ongoing oversight of food-contact materials. Although the evaluation does not automatically prohibit every phthalate under review, it gives the packaging supply chain a clear reason to pay attention to future assessments and relevant regulatory developments.
Procurement managers should review existing supplier records, identify materials that require closer examination and ensure that documentation matches each product's intended application. Chemical traders should prepare to answer customer questions about composition, authorization, testing and alternative formulations with clear, product-specific information.
Companies that build these checks into routine purchasing can improve supplier accountability and reduce avoidable compliance delays. They can also strengthen commercial relationships by helping customers understand what they are buying and where the material can appropriately be used.
For the wider chemical trade, the key priority is not to treat a regulatory review as a simple yes-or-no verdict on an entire chemical family. It is to connect scientific evidence, intended use, product documentation and market-specific requirements when selecting packaging materials.
