PPWR supplier questionnaires are beginning to turn legal text into supplier-management reality. At Waste2Wear, we are seeing this first hand. PPWR is intended to reduce packaging waste, improve circularity and harmonise packaging requirements across the EU. The European Commission describes the regulation as part of the EU's work to make packaging more sustainable, reduce unnecessary packaging and increase recycling and reuse.
The regulation also addresses the composition of packaging, including substances of concern. Under PPWR, the combined concentration of lead, cadmium, mercury and hexavalent chromium in packaging or packaging components must not exceed 100 mg/kg. The regulation also introduces restrictions for PFAS in food-contact packaging, with limits expressed at the level of targeted PFAS, the sum of targeted PFAS and total fluorine. Total fluorine is restricted to 50 mg/kg for food-contact applications.
These requirements do not affect every packaging application in the same way. However, they do make supplier visibility more important. Buyers need to understand the materials, coatings, inks, adhesives and auxiliary substances used in packaging, and they need to know what evidence is available to support supplier declarations.
For recycled packaging suppliers, this raises the standard. A recycled material needs to be supported by documentation that helps the buyer assess material source, composition, claim validity and compliance readiness.

What brands should ask recycled packaging suppliers
A useful supplier questionnaire should help buyers move beyond broad recycled-content claims and understand the evidence behind the material. Before sourcing recycled packaging, brands should ask suppliers to confirm the following points.
For the wider context on what PPWR asks of buyers and the evidence a recycled content claim should rest on, see our guide to PPWR requirements for recycled packaging buyers.
1. What recycled material stream is being used?
Buyers should ask whether the material is post-consumer or post-industrial, and what type of source material it comes from. For recycled polypropylene, recycled polyethylene or recycled polyester, the input stream can influence traceability, technical properties, regulatory exposure and the documentation available.
For recycled packaging, this question is especially important because the source material may affect how easily a supplier can provide supporting evidence, and how that evidence aligns with substances of concern and food-contact requirements where they apply.
2. What evidence supports the recycled-content claim?
Suppliers should be able to explain how recycled content is verified. Depending on the product and material, this may include certification, transaction documentation, third-party testing, traceability records or per-order reporting.
The aim is not only to confirm that recycled content is present. It is to understand whether the claim can be supported in a way that is useful for the buyer's own compliance, reporting and procurement records.
3. Can the supplier provide material declarations or test reports?
PPWR increases the importance of knowing what packaging is made from. Buyers should ask whether suppliers can provide relevant declarations, test reports or material information for the packaging and its components.
This may include information on the base material, coatings, inks, adhesives and other substances used during production. Some documentation may be available at material level, while other information may depend on the final product specification.
4. Has the supplier considered substances of concern?
Supplier questionnaires should ask how substances of concern are assessed and documented. This is particularly relevant where packaging may involve food-contact applications, coatings, inks, adhesives or other components that require closer review.
Not every packaging product will carry the same risk profile. However, buyers should still understand whether the supplier has a process for identifying relevant substance requirements and providing supporting evidence where needed.
5. Is the evidence representative or order-specific?
The questionnaires we are receiving generally offer two options for advance documentation. Suppliers can either provide representative evidence from their supply chain or external test laboratories, such as declarations and test reports, or they can provide a general written declaration of conformance to PPWR for the materials they supply. Other information will only be available at enquiry or job level, particularly where labelling, construction, print or coating are involved.
Buyers should clarify this distinction early. A general supplier declaration can be useful for material-level questions, but it may not answer every question for a specific product configuration. Knowing where the line sits helps procurement teams plan documentation requests around quoting and order placement rather than around the application date.
6. Can the supplier support the brand's Technical Documentation?
Because the brand owner is generally the manufacturer for PPWR purposes, the EU Declaration of Conformity and Technical Documentation are prepared and held by the brand. Supplier information is one of the inputs into that file. This includes material declarations, test reports and evidence relating to substances of concern, packaging composition and minimisation.
This makes documentation support a procurement consideration rather than only a compliance task. Buyers should know whether suppliers can provide the right information in a usable format, in advance of deadlines becoming urgent, and whether that information can be referenced inside the brand's own Technical Documentation.

Which third-party reports are acceptable proof of recycled content
Buyers asking this question are usually holding a supplier response and trying to work out whether it is enough. The honest answer is that different evidence types answer different questions, and a questionnaire that treats them as interchangeable will accept weak proof alongside strong.
Scheme certification sits at the top for material provenance. A Global Recycled Standard certificate confirms that a certified operator has been audited against a recognised standard, and the transaction certificates issued under it tie a specific shipment to that audited system. A certificate on its own tells a buyer that the system exists. The transaction documentation is what connects it to the goods being purchased, so buyers should ask for both rather than accepting the scope certificate alone.
Laboratory test reports answer a different question. Where a requirement is expressed as a numerical limit, as the PPWR heavy metal limit of 100 mg/kg and the 50 mg/kg total fluorine limit for food-contact applications are, a written statement from a supplier does not produce a number. A test report from an accredited laboratory does. For food-contact packaging in particular, buyers should expect analytical results for the specific packaging type rather than a general assurance covering a supplier's range.
Supplier declarations are useful and are not the same thing as proof. A declaration of conformity records what a supplier believes to be true about the materials it has received and processed. It is appropriate for material-level questions and it becomes unreliable where a treatment has been applied further down the chain, because a supplier can issue an accurate declaration about inputs while a coating applied elsewhere introduces something it never saw.
Per-order reporting closes the gap between the certificate and the shipment. Every Waste2Wear production run is delivered with an Environmental Impact Report covering the recycled material used and the energy, water and CO2 savings against virgin equivalents, which gives a buyer a document tied to the order rather than to the supplier in general. For recycled polyester specifically, our RA3 verification methodology has been independently validated by Wessling.
This is also where verification methods differ in what they actually deliver. Many recycled-content tests return a probability that recycled material is present, or a band it is likely to fall within, which leaves a buyer holding a range at the point they need a figure for a hang tag or a technical file. RA3 returns the exact percentage of recycled PET bottle content in the sample tested. For brands whose claims have to survive a challenge, the difference between a likelihood and a number is the difference between a claim you can defend and one you have to qualify.
The practical test for a questionnaire response is whether the evidence names the material, names the order or product it applies to, and can be placed inside your Technical Documentation without further explanation. Evidence that only names the supplier is a starting point rather than an answer.
Â
Why recycled content alone is not enough
Recycled packaging has an important role to play in more circular packaging systems. PPWR supports the increased use of recycled plastics in packaging, but it also raises expectations around safety, documentation and verifiable claims.
This is where recycled packaging sourcing becomes more strategic. The question is not only whether a supplier can produce packaging from recycled material. Buyers also need to understand what the material is, where it comes from, how the recycled-content claim is supported, and whether the supplier can provide evidence that fits the buyer's compliance process.
For procurement and sustainability teams, this creates a new baseline. Recycled-content claims need to be supported by material evidence. Supplier declarations need to be specific enough to be useful. Documentation needs to be available before it becomes urgent.

What a sustainable packaging questionnaire should cover beyond PPWR
Not every buyer sending a packaging questionnaire is working to PPWR. Brands selling outside the EU, brands with retailer commitments that run ahead of regulation, and brands answering customer ESG requests are all asking similar questions for different reasons, and a questionnaire built only around one regulation will miss the parts that apply regardless of jurisdiction.
Four areas hold their value whatever the driver. The first is material identity, meaning what the packaging is actually made from at each layer, including films, coatings, inks and adhesives rather than only the substrate. The second is recycled content and how it is evidenced, which is the same question PPWR asks and which retailers and reporting frameworks have been asking for longer. The third is recyclability in practice, meaning whether the packaging separates cleanly in the collection systems of the markets where it is sold, which is a different question from whether the material is theoretically recyclable. The fourth is the environmental data a supplier can produce per order, because a claim made in a sustainability report needs a number behind it that someone can trace.
Buyers who build a questionnaire around these four areas will find that the PPWR-specific requirements slot into the same structure rather than needing a separate exercise. The regulation raised the standard of proof. It did not invent the questions.
What to send a supplier instead of a questionnaire
Questionnaires are not always the fastest route to the documents a buyer needs. A thirty-question survey sent to ten suppliers produces ten differently formatted responses that then have to be normalised before anyone can compare them, and much of what comes back will be prose where a document was wanted.
The alternative is to skip the interpretation step and request the artefacts directly. A short document request naming what you need, in what format, and for which packaging type will usually return a usable file faster than a questionnaire will return a usable answer. For recycled packaging that request generally covers the scheme certificate and its scope, transaction documentation for the relevant shipments, laboratory test reports for any substance limits that apply to the application, and whatever per-order environmental reporting the supplier produces as standard.
The two approaches suit different stages. A questionnaire is the better tool early, when you are comparing suppliers you do not yet know and want to see how they think about evidence. A document request is the better tool once a supplier is shortlisted, because at that point you are building a file rather than forming an impression. Suppliers who already hold this documentation will return it quickly, and how quickly a supplier can produce it is itself a reasonable signal.

Waste2Wear's view: how we answer the six questions
We produce finished products and reusable packaging using recycled materials, including recycled polypropylene reusable bags. As PPWR moves closer to application, we see supplier documentation becoming a core part of responsible recycled packaging sourcing, and we have built our material and certification stack to answer the questions buyers are now asking.
Material stream
On material stream, our recycled polypropylene reusable bags are produced from post-consumer feedstock, and we are transitioning toward exclusively food-grade post-consumer packaging as the input source. This is a proactive step designed to align our material strategy with the direction of incoming EU requirements around packaging safety, traceability and substances of concern.
Evidence for recycled-content claims
On evidence for recycled-content claims, every Waste2Wear production run is delivered with an Environmental Impact Report (EIR). The EIR provides per-order data on the recycled material used and the energy, water and CO2 savings compared with virgin equivalents, and accompanies each individual order as our standard evidence document. More information on the EIR is available at waste2wear.com.
For brands that require additional verification on recycled polyester (rPET) specifically, we also have RA3, our in-house recycled content verification methodology. The RA3 methodology has been independently validated by Wessling, a German testing and certification institute. For brands that require third-party documentation, Wessling can conduct independent testing on request and issue their own certified results.
Declarations and test reports
On declarations and test reports, we can provide representative material information at supplier level and supporting evidence on request. Our factories also carry BSCI, GOTS and RDS certifications, which sit alongside material-level evidence as part of the wider documentation package available to buyers.
Substances of concern
On substances of concern, our food-grade post-consumer packaging transition is specifically intended to strengthen our position on input quality for applications where substance restrictions are most relevant.
Representative versus order-specific evidence
On the representative versus order-specific question, we work with buyers to provide material-level documentation in advance, and product-level or order-level documentation where construction, print or coating make general evidence insufficient.
Technical Documentation support
On Technical Documentation support, we provide material and certification information in a format that can be referenced inside the buyer's own conformity assessment file.

The practical takeaway
PPWR is shifting the packaging conversation from broad claims toward evidence. For brands sourcing recycled packaging, now is the time to review supplier questionnaires, documentation requirements and material specifications. Before August 2026, buyers should know whether their recycled packaging suppliers can provide clear information on material streams, recycled-content evidence, substances of concern and documentation support.
The earlier these questions are asked, the easier they are to answer.
