PPWR is not only an importer issue.
Packaging suppliers and manufacturers also need to prepare better documents, clearer traceability, and stronger product data before selling into EU supply chains.
For compostable bag suppliers, this means more than showing an EN 13432 certificate.
EU buyers will ask for technical documentation, conformity evidence, batch traceability, product specifications, and a clear link between certificates and finished packaging.
This guide explains PPWR manufacturer requirements from a practical supplier and B2B buyer view.
What Are PPWR Manufacturer Requirements?
The Packaging and Packaging Waste Regulation, Regulation (EU) 2025/40, sets rules for packaging placed on the EU market.
The European Commission states that the PPWR entered into force on 11 February 2025 and will generally apply from 12 August 2026.
For manufacturers, the core duty is simple:
Packaging should not be placed on the EU market unless it meets the applicable PPWR requirements.
Under Article 15, manufacturers must make sure packaging is designed and produced according to the relevant rules. They must also carry out, or have carried out, the conformity assessment procedure.
When conformity is shown, the manufacturer must draw up technical documentation and an EU Declaration of Conformity.
Who Is the Manufacturer Under PPWR?
The manufacturer is not always only the physical factory.
In many supply chains, the manufacturer can be the company that places packaging on the market under its own name or trademark.
This matters for:
- Brand owners
- Private-label buyers
- OEM packaging projects
- Importers using their own brand
- Retailers commissioning packaging
- Packaging suppliers producing custom printed bags
If a buyer controls the design, brand, and claims, the role should be checked carefully.
A Chinese factory may be the physical producer.
But the EU buyer may become the manufacturer in some private-label situations.
Role mapping should happen before mass production.
Manufacturer vs Supplier: Why the Role Matters
PPWR uses different roles.
A supplier may provide packaging materials, bags, inks, labels, cartons, or components. A manufacturer has direct conformity duties for the packaging placed on the market.
| Role | Main Duty |
|---|---|
| Manufacturer | Ensures packaging conformity and prepares required documentation |
| Supplier | Provides data and evidence needed to prove conformity |
| Importer | Checks conformity before placing packaging on the EU market |
| Distributor | Acts with due care before making packaging available |
| Authorised representative | Acts under written mandate for defined tasks |
Article 16 is important for suppliers. It requires suppliers of packaging or packaging materials to provide manufacturers with the information and documentation needed to demonstrate conformity.
In plain English:
If you supply packaging into an EU chain, buyers will need your data.
What Packaging Manufacturers Must Prepare
Technical Documentation
Technical documentation is the evidence file behind the conformity claim.
It should show how the packaging meets the relevant PPWR requirements.
For compostable bags, the file may include:
- Product description
- Material composition
- Bag size and thickness
- Resin grade information
- Printing ink information
- Compostability evidence
- Heavy metal data
- Food-contact documents, if applicable
- Labelling information
- Test reports
- Certificates
- Supplier declarations
- Batch traceability records
Technical documentation is not the same as a sales brochure.
It is a compliance evidence file.
Conformity Assessment
Article 38 says conformity assessment must be carried out before packaging is placed on the market.
The purpose is to check whether the packaging meets the relevant PPWR requirements.
For compostable packaging, this may involve reviewing:
- Substance restrictions
- Packaging minimisation
- Compostability requirements, where applicable
- Labelling requirements
- Claims made on the packaging
- Finished product evidence
- Supporting test reports and certificates
A conformity assessment should be linked to a specific packaging type, not a vague product family.
EU Declaration of Conformity
Article 39 requires the EU Declaration of Conformity to state that the relevant PPWR requirements have been met.
Annex VIII gives the model structure.
The DoC is the signed statement.
The technical file is the evidence behind it.
A DoC should identify:
- Packaging type
- Manufacturer
- Product description
- Relevant EU legislation
- Standards or specifications used
- Responsible signature
- Date and place of issue
A DoC should not be copied from one product to another without checking the actual packaging.
Traceability and Identification
Article 15 also requires manufacturers to ensure packaging bears a type, batch, or serial number, or another element that allows identification.
If the packaging size or nature does not allow this, the information can be provided in an accompanying document.
For B2B suppliers, traceability should connect:
- Raw material batch
- Production order
- Machine or line record
- Finished bag SKU
- Printing version
- Carton label
- Shipment batch
- Test or certificate file
- Customer order
Traceability is not only for audits.
It helps solve real production problems faster.
Instructions, Labels, and Buyer Information
Manufacturers must also make sure packaging is accompanied by required instructions and information.
For EU buyers, this can include:
- Material information
- Sorting or disposal information
- Compostability wording
- Importer or manufacturer identification
- Digital data carrier information, where relevant
- Any warnings or use limits
If a compostable bag is printed with claims, the supplier should check whether those claims match the evidence.
“Compostable” should not be treated as a design word only.
It is a claim that needs support.
What Should Be in the PPWR Technical File?
Annex VII sets out the technical documentation structure.
For a practical packaging supplier, the file should be organized by packaging type or SKU.
| Technical File Item | Why It Matters |
|---|---|
| General packaging description | Defines exactly what the file covers |
| Design drawings or specifications | Links evidence to size, thickness, and structure |
| Material composition | Supports substance and material checks |
| Test reports | Shows lab evidence for specific properties |
| Certificates | Supports third-party certification claims |
| Supplier declarations | Provides upstream data |
| Conformity assessment explanation | Shows how the conclusion was reached |
| Label and artwork version | Connects claims and legal markings to the product |
| Batch traceability method | Helps link product to production records |
| DoC copy | Shows signed conformity statement |
For compostable bags, the technical file should make one thing clear:
Is the evidence for raw material or finished packaging?
That single question prevents many buyer mistakes.
Certificate vs Test Report vs Supplier Declaration vs DoC
These documents are often mixed together.
They should not be.
| Document | What It Is | What It Is Not |
|---|---|---|
| Certificate | Third-party confirmation under a scheme or standard | Not a full PPWR technical file |
| Test report | Lab result for a sample | Not always proof for every size or print version |
| Supplier declaration | Supplier’s statement about material or component | Not independent testing |
| Technical documentation | Full evidence file | Not a single certificate |
| EU Declaration of Conformity | Signed legal statement | Not the evidence itself |
A certificate can support the DoC.
But it does not replace the DoC.
A test report can support the technical file.
But it may not cover changed thickness, new ink, or a different structure.
Raw Material Evidence vs Finished Packaging Evidence
This point is especially important for compostable bags.
A raw material certificate may cover the resin.
But the finished bag has more variables:
- Film thickness
- Bag size
- Sealing
- Printing ink
- Color masterbatch
- Additives
- Handles or drawstrings
- Perforation
- Roll format
- Retail packing
If the finished product differs from the tested sample, the supplier should check whether the evidence still applies.
For EU buyers, a good supplier should be able to explain the link between raw material, finished packaging, and certification scope.
Decision Table for Packaging Suppliers
| Situation | What the Supplier Should Prepare |
|---|---|
| Selling plain compostable bags to an EU importer | Product specs, certificate scope, finished product evidence, traceability |
| Producing private-label printed bags | Artwork review, claim check, print version control, buyer role mapping |
| Changing film thickness | Review whether test evidence and certificate scope still apply |
| Using new ink or additive | Check impact on compliance and claim support |
| Supplying food-contact bags | Separate food-contact documentation from PPWR documents |
| Buyer asks for PPWR DoC | Confirm who is the manufacturer and who signs the DoC |
| Buyer asks for technical documentation | Provide relevant data while protecting confidential formula details |
| Supplying only raw material | Provide material declarations and test evidence, not finished packaging claims |
Supplier Checklist Before Selling to EU Buyers
Before accepting an EU order, a packaging supplier should prepare:
- Product specification sheet
- Material composition summary
- Finished product test evidence
- Certificate scope confirmation
- Raw material supplier declarations
- Heavy metal or restricted substance information
- Food-contact evidence, if applicable
- Artwork and label review record
- Batch traceability method
- Production quality control records
- Technical documentation inputs
- DoC information or draft structure
- Change control process
- Document version control
For OEM projects, this should happen before printing and mass production.
Not after shipment.
Red Flags for Importers Reviewing Suppliers
EU buyers should be careful if a supplier says:
- “Our material certificate covers every bag.”
- “We do not track batch numbers.”
- “The same DoC can be used for all products.”
- “Artwork claims are the buyer’s problem.”
- “No need to review ink or thickness changes.”
- “We cannot explain whether evidence covers raw material or finished packaging.”
- “PPWR compliant” without technical documentation support.
These answers may show weak compliance control.
They may also create delay when an importer needs documents for authorities or customers.
B2B Procurement Case
An EU wholesaler wants to buy custom printed compostable garbage bags from a Chinese supplier.
The buyer asks for EN 13432 evidence.
The supplier sends a resin certificate only.
But the final product will have:
- Larger bag size
- Thicker film
- Custom green printing
- Retail carton artwork
- Private-label claims
- New packing format
A stronger supplier response would include:
- Finished bag specification
- Certificate scope explanation
- Ink and print review
- Material composition summary
- Batch traceability plan
- Technical documentation inputs
- DoC role discussion
- Change control for future repeat orders
The second response gives the buyer a clearer path.
It also reduces back-and-forth before shipment.

FAQ
What are PPWR manufacturer requirements?
PPWR manufacturer requirements are the duties packaging manufacturers must meet before packaging is placed on the EU market. They include conformity assessment, technical documentation, EU Declaration of Conformity, identification, traceability, and required packaging information.
Does a packaging supplier need to prepare technical documentation under PPWR?
If the supplier is the manufacturer, yes. If the supplier is not the manufacturer, it still may need to provide information and documents that the manufacturer needs to prove conformity.
Is a compostability certificate enough for PPWR?
No. A compostability certificate may support the evidence file, but it does not replace technical documentation, conformity assessment, traceability records, or the EU Declaration of Conformity.
What is the difference between technical documentation and a DoC?
Technical documentation is the evidence file. The EU Declaration of Conformity is the signed statement that says the packaging meets the relevant PPWR requirements.
Should evidence cover raw material or finished packaging?
For compostable bags, buyers should check both. Raw material evidence is useful, but finished packaging evidence is needed when thickness, ink, additives, sealing, or format may affect compliance.
What traceability should packaging suppliers keep?
Suppliers should be able to link raw material batches, production orders, finished SKUs, artwork versions, carton labels, shipment batches, and document versions.
Conclusion
PPWR manufacturer requirements make supplier preparation more important.
Packaging manufacturers need more than certificates. They need clear product specifications, technical documentation inputs, conformity evidence, batch traceability, and careful control of claims and artwork.
For EU buyers, the best supplier is not only the one with a good price.
It is the supplier that can explain what each document covers, how the finished packaging is controlled, and how changes are tracked before production starts.
