I. Core Requirements for PPWR Testing of Corrugated Cardboard Boxes
1. Mandatory Test Items and Limits
Heavy Metals: The total of lead (Pb), cadmium (Cd), mercury (Hg), and hexavalent chromium (Cr⁶⁺) ≤ 100 mg/kg
Testing Standards: EN1122 (Cadmium and Lead), IEC62321 (Mercury/Hexavalent Chromium)
Note: Inks, adhesives, laminating materials, and other auxiliary materials must be tested separately and cannot be tested together with the main body of the cardboard box.
2. Report Qualification Requirements
The report must be issued by a third-party laboratory accredited by ISO 17025 (DEZEW Testing CNAS Registration No.: L8083).
Domestic institutions are advised to choose those with both CNAS and CMA accreditation, as their reports are globally recognized.
3. Sample Submission Rules
For cartons of the same batch, material (same base paper/ink/adhesive), and structure, only one representative sample is required.
Complete cartons are not required; cut sections of homogeneous material such as corrugated paper, printing layer, and adhesive layer are sufficient for testing.
II. Required Contents of the Test Report
A qualified PPWR test report must include:
Sample Information: Material, specifications, production batch, submission date
Testing Basis: Clearly indicate the PPWR regulation (EU2025/40) and corresponding EN/ISO standards
Test Results: Individual heavy metal content data + total data
Compliance Conclusion: Clearly state whether it complies with PPWR limits
Laboratory Qualifications: ISO17025 certificate number, CNAS/CMA accreditation certificate
Additional Documents: Original test spectrum, calibration certificate, Declaration of Conformity (DoC)
III. Compliance Timeline
1. August 12, 2026: PPWR officially takes effect; all corrugated cartons exported to Europe must provide a heavy metal test report.
2. February 12, 2027: The EU will release standards for minimizing packaging (void ratio/wall thickness limits).
3. January 1, 2030: Mandatory requirements for packaging recyclability ≥70% and recycled material content of plastic packaging ≥35%.
IV. Frequently Asked Questions
1. Do cartons of the same material but different sizes need to be tested separately?
No, as long as the raw materials, production processes, and suppliers are completely identical, differences in size can be grouped together for testing.
2. Can reports from the old Packaging Directive (94/62/EC) still be used?
No, after PPWR comes into effect, a test report issued according to the new regulations must be provided. Hexavalent chromium must be measured separately; it cannot be extrapolated from total chromium data.
3. Are there any additional requirements for food contact corrugated cartons?
Yes, further testing for perfluorinated compounds (PFAS) is required:
Total fluoride ≤ 50 ppm → Compliant
Total fluoride > 50 ppm but organic fluorides ≤ 50 ppm → Compliant
Organic fluorides > 50 ppm → Targeted testing of PFAS monomers is required, with each monomer ≤ 25 ppb and the total ≤ 250 ppb.
