If you import food packaging from China into the European Union, the PFAS issue is no longer a future concern; it is a present compliance requirement. Under the EU PPWR, which took effect on August 12, 2026, PFAS in food-contact packaging is restricted to near-zero levels. For most Chinese packaging manufacturers who still rely on fluorinated coatings, this represents a fundamental shift.
This guide explains what PFAS are, why the EU has restricted them, where they commonly appear in Chinese food packaging, and how to source compliant alternatives without sacrificing performance or cost. If switching coatings also means new production equipment, see our directory of Chinese food packaging machinery manufacturers.
What Are PFAS and Why Does the EU Restrict Them?
PFAS, per- and polyfluoroalkyl substances, are a family of over 10,000 synthetic chemicals characterised by strong carbon-fluorine bonds. This bond makes PFAS extraordinarily resistant to heat, water, oil, and chemical degradation, which is precisely why they have been widely used in food packaging for decades.
Common applications in food packaging include:
- Grease-resistant coatings on burger wrappers, sandwich paper, and bakery bags.
- Oil and water barriers on microwave popcorn bags and fast-food containers.
- Non-stick coatings on baking paper and release liners.
- Waterproof treatments on paper cups, takeaway containers, and paper plates.
The problem: PFAS do not break down in the environment. They accumulate in water, soil, and living organisms, including humans. Research has linked PFAS exposure to immune system suppression, hormonal disruption, increased cancer risk, and developmental effects in children. The EU classifies PFAS as “Substances of Very High Concern” under REACH, and PPWR now specifically targets them in food-contact packaging.
What the PPWR PFAS Limit Numbers Mean
The PPWR sets two thresholds for PFAS in food-contact packaging:
| Parameter | Limit | What It Covers |
|---|---|---|
| Individual PFAS substance | ≤ 25 ppb (parts per billion) | Any single PFAS compound measured in the packaging material |
| Total PFAS (sum) | ≤ 250 ppb | The combined concentration of all detectable PFAS substances |
To put these numbers in perspective: a typical fluorinated grease-resistant coating applied to food packaging contains PFAS orders of magnitude above these thresholds, typically in the thousands of ppb, orders of magnitude above the PPWR limit. This means any packaging that intentionally uses PFAS for functional performance will fail compliance.
The 25 ppb individual limit is effectively a non-detect threshold. It allows trace-level background contamination from recycled fibres, water, or the manufacturing environment, but it prohibits intentional PFAS use.
Where PFAS Hides in Chinese Food Packaging
Chinese food packaging manufacturers have been among the world’s largest users of PFAS-based coatings, largely because they are effective, inexpensive, and widely available. Here are the highest-risk product categories:
High-Risk Packaging Types
- Moulded fibre / bagasse containers, clamshell food containers made from sugarcane fibre or bamboo pulp are almost always treated with PFAS for oil and water resistance. These are extremely common in Chinese export packaging.
- Greaseproof paper and wrappers, paper used for burgers, sandwiches, and fried foods. The grease resistance is often achieved through PFAS-based chemical sizing rather than mechanical processing.
- Paper cups and bowls, while the PE lining itself is not PFAS, the paperboard substrate may contain PFAS as a wet-strength agent.
- Corrugated cardboard for food, recycled cardboard may contain PFAS from upstream contamination (recycled office paper, printed materials).
- Silicone-coated baking paper, generally safe, but low-cost alternatives may use PFAS-based release agents instead of food-grade silicone.
Hidden PFAS Sources
Beyond intentional coatings, PFAS can enter food packaging through less obvious pathways:
- Recycled fibre contamination: If your packaging uses recycled paper or cardboard, PFAS from the original materials may carry through the recycling process.
- Processing aids: PFAS may be used as release agents in paper manufacturing, even if they are not part of the final product specification.
- Printing inks and adhesives: Some fluorinated surfactants used in ink formulations contribute to total PFAS levels.
- Water supply: Factory water contaminated with PFAS can introduce trace levels into packaging materials.

How to Verify PFAS-Free Claims from Chinese Suppliers
“PFAS-free” is a marketing term that currently has no standardised definition in China. Some suppliers claim PFAS-free status while still using fluorinated processing aids or sourcing from sub-suppliers who do. Here is how to verify supplier certificates and compliance documents:
Require Total PFAS Testing
Request a total PFAS screening as part of your quality control testing, not just tests for PFOA and PFOS (the two most well-known PFAS). A proper screen should test for at least 30–50 individual PFAS compounds and report the sum total. The result must fall below 250 ppb total and 25 ppb for any individual substance.
Use Accredited Laboratories
Testing should be conducted by ISO 17025-accredited labs. In China, the most accessible options include:
- SGS (Shenzhen, Shanghai, Guangzhou).
- TÜV Rheinland (Shenzhen, Guangzhou).
- Intertek (Shenzhen, Shanghai).
- Eurofins (Shanghai, Suzhou).
Budget approximately USD 500-1,500 per sample for comprehensive PFAS screening, with a turnaround of 10-15 business days.
Audit the Supply Chain, Not Just the Final Product
A finished packaging product may test clean, but if the factory also handles PFAS-treated materials on the same production line, cross-contamination is possible. Request information about:
- Whether the factory uses PFAS in any product line (not just yours).
- Cleaning protocols between PFAS and non-PFAS production runs.
- Sub-supplier declarations for raw paper, fibre, or coating materials.
Managing the Cost Impact of PFAS-Free Packaging
Transitioning from PFAS to PFAS-free alternatives typically increases packaging costs by 15-50%, depending on the alternative chosen. Here are strategies to manage the cost impact:
- Volume commitments: Lock in pricing by committing to annual volume agreements with your packaging supplier. PFAS-free coatings are becoming mainstream, and volume drives cost reduction.
- Right-size the specification: Not every food product needs the highest-performance barrier. A dry snack food needs less grease resistance than a fried food item. Match the coating performance to the actual product requirement.
- Consolidate packaging SKUs: If you source multiple product lines from China, standardise on a single PFAS-free packaging format where possible to achieve better economies of scale.
- Factor in compliance cost: The cost of PFAS-free packaging is far lower than the cost of non-compliance; each EU country sets its own penalties, and some proposals tie fines to annual turnover.
Frequently Asked Questions
Is all food packaging from China contaminated with PFAS?
No. Many Chinese manufacturers have already transitioned to PFAS-free production, especially those exporting to the EU, US, and markets with active PFAS regulations. However, PFAS-based coatings remain common in lower-cost packaging and products made primarily for the domestic Chinese market. Always verify with testing, not just supplier claims.
Can I detect PFAS in packaging myself without lab testing?
Not reliably. There are no commercially available rapid tests for PFAS in packaging that can detect levels at the 25 ppb threshold required by PPWR. Laboratory analysis using LC-MS/MS or GC-MS/MS is the only way to confirm compliance.
Does the PPWR PFAS ban apply to all packaging or only food contact?
The specific 25 ppb / 250 ppb limits apply to food-contact packaging. Non-food packaging is subject to the general substance restrictions under PPWR and REACH, which may also restrict certain PFAS but through different mechanisms.
What about PFAS in packaging made from recycled materials?
Recycled fibre can carry PFAS contamination from upstream sources. If your packaging uses recycled content, it should still be tested for total PFAS. The PPWR does not provide exemptions for recycled materials.
Will PFAS-free coatings affect the shelf life of food products?
In some cases, yes, particularly for products requiring high oil barrier performance. Silicone-based alternatives offer comparable performance for most applications, but you should validate shelf life through migration and barrier testing before switching.
My supplier says their packaging is “FDA compliant”. Does that mean PFAS-free?
No. FDA compliance and EU PPWR compliance are different standards. The FDA has approved certain PFAS for food-contact use, while the EU has essentially banned them at the 25 ppb threshold. A packaging product can be FDA-compliant and still fail PPWR requirements.
