A standard 500ml PET bottle creates at least 37 PPWR obligations across its lifetime. In this article Dr Steven Brennan, CEO of Foresight, follows a single bottle through its lifecycle, from raw materials and component production to filling, sale, collection and recycling, to learn more about the PPWR and its core stipulations.
The Packaging and Packaging Waste Regulation (PPWR) generally applies on 12 August 2026 and many duty holders we speak with are still working out how to deal with it. The legislation itself is 80,000 words and the Commission’s guidance is another 36,000.
That’s a lot of reading and interpretation for business impact assessments and action planning. We wanted to make the new duties more accessible by bringing it to life using a simple product that triggers duties under the PPWR.
We chose a 500 ml PET water bottle because it appeared to be a simple place to start. Most people looking at it would see three parts: the bottle, its cap and a label. Once our team began mapping it for The Life of aPackage, those three parts became eight. Alongside the PET body were a closure and liner, a label or sleeve, adhesive, ink, grouped packaging and transport packaging.
Following the bottle added another layer. Its journey began with material production and continued through packaging manufacture, filling, import, distribution and retail.
Consumption was followed by collection, sorting and recycling, with secondary material at the end. That gave us 11 stages, ten handovers and 38 verified obligation records.
Not all 38 obligations apply immediately, and they do not all have the same status. Some are already fixed in the Regulation; others apply later or depend on technical criteria that are still being developed.
What interested us was how often the person responsible for a decision depended on evidence created somewhere else. Responsibility moved along the supply chain, while the information needed to discharge it was spread across several organisations.
The evidence behind one bottle
For the supply chain we mapped, the operator responsible for the finished package has to assess the complete packaging unit and prepare its technical documentation. That assessment cannot stop at the PET body. It has to account for the cap, liner, label, adhesive and ink, as well as the way those components work together.
Different suppliers understand different parts of that picture: a resin producer controls information about the material grade and composition; the closure supplier knows the cap specification; and a label converter may itself rely on information from suppliers of stock, ink and adhesive.
Article 16 of the PPWR reflects this division of knowledge. Suppliers of packaging or packaging materials must give the manufacturer the information and documents needed to demonstrate conformity, including relevant technical documentation for the requirements in Articles 5 to 11. Without that duty, the manufacturer could be legally responsible for an assessment while having no reliable route to the evidence behind it.
Providing a document, however, is not the same as providing usable evidence. A declaration headed “plastic packaging” may leave its recipient unsure whether it applies to the bottle body, cap, label or liner. Test results may be technically sound but relate to a grade that is no longer purchased, while composition information may omit the production site or supporting specification. A folder can therefore appear complete until someone tries to apply its contents to a particular bottle.
The handover from packaging manufacture to filling brings these dependencies together: the converter supplies the empty bottle and component information, while the operator responsible for the filled package must assemble the drawings, specifications, declarations, risk analysis and test evidence supporting the complete unit.
Although much of the evidence originates upstream, it must remain traceable to the bottle type, component specification or production batch covered by the technical file. A report that cannot be matched to the current packaging does not resolve the conformity question.
This is why the regulatory record needs more than a collection of PDFs. It has to identify the component and supplier, show which evidence supports the applicable assessment and preserve enough history to establish whether the package has changed since that evidence was produced.
Where continuity breaks
Routine substitutions put the record under pressure. Suppose the usual closure becomes unavailable and procurement finds another that fits the same bottle and performs in the same way. Production may be able to use it without changing the filling line, but those practical similarities do not answer every PPWR question.
Its material grade, liner, colourant or additive package may be different; existing substance information may no longer cover it; and its behaviour during sorting or recycling may need to be checked.
None of this means that the replacement cap is non-compliant. The point is that a commercial substitution can change the basis of an assessment even when the component looks and functions like the one it replaces. Similar questions arise if a converter changes label stock, a printer alters an ink formulation, an adhesive is reformulated or production moves to another site.
Article 15 requires manufacturers to take account of changes in packaging design or characteristics and to reassess conformity where it could be affected. In practice, that connects supplier notification to internal approval.
Agreements need to establish which changes a supplier will report and which specifications its evidence covers; procurement and packaging teams then need a way to route relevant changes back into the conformity review. Otherwise the physical package moves on while its technical file remains attached to the previous version.
Continuity becomes harder to see once the bottle leaves the manufacturer, but it does not cease to matter. Importers, distributors, retailers and waste operators have different responsibilities and do not all need the complete technical file. What must persist is the ability of the responsible actor at each stage to obtain the information relevant to its decision and understand precisely which packaging it covers.
Timing adds another complication. A requirement marked as “assessed” may have been completed, found not yet applicable or reviewed only to the extent permitted by current technical criteria, so the record must capture the conclusion, supporting evidence and date for reassessment.
Follow the package, not only the Regulation
Reading the PPWR and building a legal checklist are essential, but neither shows whether a company can connect those requirements to the packaging it buys, manufactures and places on the market. A practical review should begin with one real package and its bill of materials, then follow them through the business.
At each handover, establish what has changed hands, including the component, material, supplier and current specification. Then trace the declarations, composition data, assessments and test reports that support it. The review should also examine change control: who must report a change, who decides whether it affects conformity and which parts of the assessment or technical file need to be revisited.
This can expose gaps that a regulation-level summary will not reveal. A component may be described too loosely to link it to a supplier declaration. A test report may relate to an obsolete grade. Procurement may be able to approve a substitute without notifying the team responsible for the conformity file. Everyone may understand the requirement, but nobody may be clearly responsible for the next decision.
By the time the bottle reaches the shelf, the individual decisions, specifications and documents sit behind one finished package. The consumer sees the bottle. The manufacturer, and where necessary the authority, must be able to see the evidence trail that supports it.
Under the PPWR, holding the right documents is only part of the task. Those documents must describe the packaging that is actually being placed on the market.
