How to Verify Packaging Materials for EU PPWR Compliance

Packaging material verification for EU PPWR compliance involves checking the composition, chemical substances, physical specifications, and supporting documentation of packaging placed on the European Union market. Under Regulation (EU) 2025/40, the Packaging and Packaging Waste Regulation (PPWR), manufacturers and importers must assess packaging against the requirements applicable to its materials, intended use, and packaging format.

The PPWR has generally applied since 12 August 2026, including restrictions on certain hazardous substances in packaging and specific PFAS limits for food-contact packaging. Additional requirements covering recyclability, recycled content, packaging minimization, and labeling have different implementation dates.

For companies sourcing packaging or packaged consumer goods from China, verification should begin with material identification and supplier documentation, followed by appropriate chemical testing, packaging design assessment, and production quality checks.

What Packaging Materials Need to Be Verified Under the PPWR?

The PPWR applies broadly to packaging placed on the EU market, regardless of its material or country of manufacture.

Packaging material verification may involve:

Plastic packaging: PET, PP, PE, PVC, and other polymer materials.
Paper and cardboard packaging: Corrugated cartons, folding boxes, paper bags, and coated paperboard.
Metal packaging: Aluminium containers, steel packaging, and metal closures.
Glass packaging: Bottles, jars, and other glass containers.
Wood packaging: Wooden boxes, crates, and certain transport packaging.
Composite packaging: Multilayer structures combining paper, plastic, aluminium, or other materials.

Verification should cover the packaging components and substances relevant to the applicable requirements.

For example, a retail product may contain a printed paperboard box, a plastic protective bag, a foam insert, an adhesive label, and a corrugated shipping carton.

Each component can have a different material composition, supplier, and compliance assessment scope.

Primary, Secondary, and Transport Packaging

Packaging verification should account for the function of each packaging component.

Packaging Type	Examples	Verification Focus
Primary or sales packaging	Bottles, pouches, retail boxes	Material composition, chemical restrictions, design, labeling
Grouped packaging	Multipacks, grouped cartons	Materials, packaging configuration, applicable design requirements
Transport packaging	Shipping cartons, protective packaging	Material specifications, dimensions, packaging minimization, applicable reuse requirements
E-commerce packaging	Mailing bags, delivery boxes, protective fillers	Material composition, packaging dimensions, applicable empty-space requirements

The regulatory assessment should consider the packaging’s classification, intended use, and applicable exemptions.

Key PPWR Requirements for Packaging Material Verification

Several PPWR provisions directly affect how packaging materials are selected, tested, and documented.

The following requirements are particularly relevant to material verification.

Restrictions on Heavy Metals in Packaging

Article 5(4) of the PPWR establishes a combined concentration limit for four heavy metals in packaging or packaging components:

Lead (Pb)
Cadmium (Cd)
Mercury (Hg)
Hexavalent chromium (Cr VI)

The combined concentration must generally remain within 100 mg/kg (100 ppm), subject to applicable provisions and exemptions.

This requirement can be relevant to packaging materials containing pigments, coatings, inks, additives, or recycled materials.

For example, a printed paperboard box may contain several inks and surface coatings. The manufacturer should establish whether the packaging and its components satisfy the applicable heavy metal restriction.

Laboratory analysis can provide supporting evidence where material composition is uncertain or independent verification is required.

PFAS Restrictions for Food-Contact Packaging

Article 5(5) establishes specific limits for per- and polyfluoroalkyl substances (PFAS) in food-contact packaging.

These restrictions have applied since 12 August 2026.

The PPWR specifies the following limits:

PFAS Measurement	Limit
Any individual PFAS measured through targeted analysis	25 ppb
Sum of PFAS measured through targeted analysis	250 ppb
PFAS, including polymeric PFAS	50 ppm

Polymeric PFAS are excluded from the first two targeted measurements. The Regulation also establishes conditions concerning the evaluation of total fluorine and supporting evidence.

The restrictions are particularly relevant to food-contact packaging where fluorinated substances may be associated with grease-resistant or moisture-resistant treatments.

Examples include:

Takeaway food containers
Fast-food wrappers
Grease-resistant paper
Bakery packaging
Coated paperboard
Microwave popcorn bags
Certain food-contact paper bags

Packaging suppliers should verify relevant coatings, barrier layers, and surface treatments.

Recyclability Requirements

Article 6 establishes requirements for packaging recyclability.

The PPWR introduces design-for-recycling criteria and recyclability performance grades, with the principal requirements applying from 1 January 2030 or the applicable later date determined by the relevant delegated acts.

Material verification should therefore consider characteristics that influence the packaging’s recyclability.

These include:

Material combinations
Multilayer structures
Adhesives
Coatings
Labels and sleeves
Closures
Inks and additives
Components that affect material separation

For example, a paperboard package containing a plastic barrier layer may require assessment of how the complete packaging structure performs within the relevant recycling process.

The applicable recyclability criteria must be evaluated according to the regulatory methodology and implementation schedule.

Recycled Content in Plastic Packaging

Article 7 establishes minimum recycled-content requirements for specified plastic packaging categories.

These requirements generally begin from 1 January 2030 or three years after the relevant implementing act enters into force, whichever is later, subject to the Regulation’s exemptions and category-specific provisions.

Packaging material verification should identify:

Polymer type
Recycled material percentage
Source of recycled plastic
Post-consumer recycled content
Supplier declarations
Material traceability records
Supporting calculation and verification evidence

The applicable recycled-content requirements depend on the packaging category and regulatory provisions.

Packaging Minimization

Article 10 establishes packaging minimization requirements that generally apply from 1 January 2030.

Packaging must be designed to minimize weight and volume while maintaining the functions necessary for the product and its distribution.

Material verification may include reviewing:

Packaging weight
Material thickness
Packaging dimensions
Protective components
Structural performance
Excessive material use

For example, a shipping carton should provide sufficient protection for the packaged goods while meeting applicable packaging design requirements.

How to Verify Packaging Materials for PPWR Compliance

A structured verification process helps manufacturers and importers identify material risks, evaluate applicable regulatory requirements, and maintain reliable compliance evidence.

The following steps can be incorporated into packaging supplier management and quality control procedures.

Step 1: Identify All Packaging Materials and Components

Begin by creating a packaging material inventory for each product or packaging format.

Record the components used in the finished packaging, including:

Main packaging material
Inner liners
Barrier layers
Coatings
Adhesives
Labels
Inks
Closures
Protective inserts
Transport cartons

For example, a takeaway food container may consist of a paperboard body, an internal barrier coating, printed exterior surfaces, and a separate lid.

The materials should be identified individually so that relevant chemical and physical requirements can be assessed.

A packaging bill of materials can help establish traceability between the finished packaging and its suppliers.

Step 2: Review Material Specifications

Request technical specifications from the packaging manufacturer and relevant material suppliers.

A material specification should provide sufficient information to identify the material and evaluate its suitability for the intended packaging application.

Useful information may include:

Material name and grade
Polymer or fibre composition
Material thickness
Basis weight or grammage
Coating composition
Recycled material content
Intended application
Food-contact status
Supplier identification
Applicable material standards

For plastic packaging, the specification should identify the relevant polymer and material grade.

For paper packaging, information may include fibre composition, grammage, coating type, and recycled content.

For composite packaging, each material layer should be identified.

Material specifications provide the foundation for determining which PPWR requirements apply.

Step 3: Verify Restricted Substances

Review whether the packaging materials and components comply with the chemical restrictions applicable under Article 5.

The assessment should address the combined heavy metal concentration limit and, where applicable, PFAS restrictions for food-contact packaging.

Supplier declarations may provide useful supporting information.

However, additional verification may be appropriate when:

Material composition is uncertain
Recycled materials are used
Coatings or additives are not fully identified
The supplier has changed
Previous testing is outdated or incomplete
A buyer requires independent verification

Relevant laboratory analysis should be selected according to the substances and materials requiring assessment.

Step 4: Conduct Appropriate Packaging Material Testing

Laboratory testing may be necessary to verify chemical restrictions or material properties relevant to compliance.

The testing program should be established according to the packaging’s composition, intended use, and applicable requirements.

For example, a paper food container with a grease-resistant coating may require a different chemical testing scope from a conventional corrugated shipping carton.

Testing should focus on the specific regulatory requirements and material risks identified during the initial assessment.

Step 5: Review Recyclability and Recycled-Content Evidence

Assess the packaging design and supplier documentation against the applicable PPWR requirements.

For recyclability, the review may include:

Material compatibility
Component separability
Coatings and adhesives
Multilayer construction
Labels and closures
Relevant recycling performance criteria

For plastic packaging subject to recycled-content requirements, supporting records should establish the recycled material source and the applicable recycled-content calculation.

Recyclability and recycled-content assessments must follow the relevant regulatory methodology when the corresponding requirements become applicable.

Step 6: Verify Packaging Dimensions and Physical Specifications

Physical verification helps confirm that production packaging matches the approved design.

Common checks include:

Packaging dimensions
Material thickness
Carton grammage
Packaging weight
Sealing quality
Structural integrity
Print quality
Label placement
Packaging configuration

For example, if a manufacturer substitutes thinner corrugated board during production, the packaging may no longer provide the specified level of protection.

A physical inspection can identify this type of material or construction deviation.

Step 7: Review Technical Documentation

The PPWR establishes conformity assessment and documentation requirements for packaging placed on the EU market.

Manufacturers must prepare the applicable technical documentation and draw up an EU Declaration of Conformity when conformity has been demonstrated under the required assessment procedure.

Supporting information may include:

Packaging specifications
Material composition records
Supplier declarations
Laboratory test reports
Chemical restriction assessments
Recycled-content documentation
Packaging design information
Relevant calculations
Product identification
Compliance records

Documentation should be traceable to the packaging design and materials actually supplied.

Step 8: Verify Production Consistency

Approved packaging materials may change during manufacturing.

Potential changes include:

Different material suppliers
Alternative coatings
Revised plastic formulations
Changes in recycled material content
Different adhesives
Modified packaging dimensions
Replacement of printed materials

Manufacturers should establish change-control procedures to identify modifications that may affect compliance.

Where a change introduces new chemical or material risks, the existing compliance evidence should be reassessed.

PPWR Packaging Material Testing Requirements

Packaging material testing should address the specific substances and properties relevant to the packaging format.

The following table provides examples of potential verification areas.

Packaging Material	Potential Verification Areas	Supporting Evidence
Plastic packaging	Heavy metals, applicable PFAS restrictions, material composition	Chemical test reports, material declarations
Paper and cardboard	Heavy metals, applicable PFAS restrictions for food-contact packaging, coatings	Laboratory reports, supplier specifications
Metal packaging	Heavy metal restrictions, coatings, material specifications	Material records, relevant test reports
Glass packaging	Applicable heavy metal requirements, material composition	Supplier declarations, analytical evidence where needed
Composite packaging	Material layers, coatings, adhesives, applicable chemical restrictions	Component specifications, relevant laboratory reports
Recycled plastic packaging	Recycled-content information, chemical risks, traceability	Supplier records, recycled-content evidence

The actual testing scope should be determined through a product-specific regulatory and material risk assessment.

Heavy Metal Testing

Chemical analysis may be used to determine the relevant heavy metal concentrations in packaging materials or components.

The results should be evaluated against the combined concentration limit established under Article 5(4), taking account of applicable exemptions.

Testing may be particularly relevant when recycled materials, pigments, or coatings introduce uncertainty about chemical composition.

PFAS Testing for Food-Contact Packaging

PFAS verification requires particular attention because the PPWR establishes specific concentration thresholds for food-contact packaging.

The European Commission’s 2026 guidance describes a stepwise approach that may involve:

Total fluorine screening
Further assessment of fluorine sources where necessary
Targeted PFAS analysis
Evaluation against the applicable regulatory limits

Total fluorine screening can help identify materials requiring additional investigation.

A total fluorine result alone may not establish the amount attributable to PFAS, particularly where non-PFAS fluorine sources are present.

The testing approach should therefore account for the analytical methods, relevant substances, and supporting evidence required.

Physical and Performance Testing

Packaging may also undergo physical testing to verify its performance against agreed specifications.

Depending on the packaging format, this may include:

Compression resistance
Burst strength
Edge crush resistance
Tensile strength
Seal strength
Drop resistance
Material thickness
Moisture resistance

These tests support packaging quality and functional performance assessments.

Their applicability should be established according to the packaging design, product requirements, and relevant PPWR provisions.

Packaging Inspection vs Laboratory Testing for PPWR Compliance

Packaging inspection and laboratory testing address different aspects of material verification.

Both may form part of a packaging quality assurance program.

Verification Area	Packaging Inspection	Laboratory Testing
Packaging dimensions	Yes	Where applicable
Material appearance	Yes	Where applicable
Print quality	Yes	Generally unnecessary
Label placement	Yes	Generally unnecessary
Carton construction	Yes	Performance tests where needed
Packaging quantity	Yes	No
Heavy metal concentration	No	Yes
PFAS concentration	No	Yes
Material composition	Limited verification against specifications	Analytical verification where appropriate
Recycled-content evidence	Document and identification checks	Method-dependent verification where available

What Can Packaging Inspection Verify?

A packaging inspection can evaluate whether manufactured packaging meets approved specifications.

Typical inspection checkpoints include:

Correct packaging materials
Packaging dimensions
Material thickness
Print and colour consistency
Label accuracy
Barcode readability
Packaging construction
Sealing quality
Carton condition
Packing configuration

These checks help identify deviations between approved packaging specifications and actual production.

What Requires Laboratory Testing?

Laboratory testing is appropriate when the verification requires chemical analysis or specialized material measurements.

For example, a visual inspection cannot determine whether a food-contact coating contains PFAS above the applicable regulatory limits.

Similarly, the concentration of restricted heavy metals cannot be reliably established through ordinary visual inspection.

Testing reports provide analytical evidence for the substances and samples included in the laboratory’s testing scope.

How Inspection Supports PPWR Compliance

Inspection can help confirm that production packaging remains consistent with the materials and specifications covered by existing compliance documentation.

For example, an importer may have approved a specific paperboard grade and coating formulation based on supplier documentation and relevant testing.

A subsequent inspection can check whether the factory is using the approved packaging material, whether dimensions remain consistent, and whether the packaging matches the approved reference.

This helps reduce the risk of undocumented material substitutions during production.

Common Packaging Material Compliance Issues

Incomplete Material Composition Information

A packaging supplier may identify a product simply as paper, plastic, or coated cardboard without providing sufficient information about additives or surface treatments.

This can make it difficult to determine the applicable chemical requirements.

Unverified Coatings and Barrier Layers

Food packaging may contain coatings that improve resistance to grease, moisture, or other conditions.

The chemical composition of these layers should be evaluated when determining applicable PFAS requirements.

Material Substitution During Production

A manufacturer may change the packaging material after the original specification has been approved.

The replacement material may have different chemical characteristics or physical properties.

Change-control procedures and production verification help identify these risks.

Unsupported Recyclability Claims

Packaging may be described as recyclable without sufficient evidence supporting the relevant regulatory criteria.

The assessment should consider the complete packaging design and the applicable PPWR methodology.

Incomplete Recycled-Content Records

A supplier may declare that packaging contains recycled plastic without providing adequate information about the material source or calculation basis.

Traceable records are important for evaluating applicable recycled-content requirements.

Test Reports That Do Not Match Production Materials

A laboratory report may cover a different material grade, coating formulation, or supplier from the one used in current production.

Reports should be reviewed against the actual packaging materials and product specifications.

Missing Technical Documentation

Packaging may have acceptable laboratory results while the supporting documentation remains incomplete.

The relevant conformity assessment and technical documentation requirements should be addressed before the packaging is placed on the EU market.

PPWR Packaging Material Verification Checklist

The following checklist can help manufacturers, importers, and quality teams organize packaging material verification.

Verification Area	Key Question
