Technical documentation under the PPWR: the data behind the declaration of conformity
Technical documentation is the data foundation for assessing packaging conformity. PakPruvo brings together packaging components, materials, weights, evidence, and versions for that purpose.
Technical documentation is the foundation for demonstrating packaging conformity in a traceable way.
The PPWR points to the requirements in Annex VII for this purpose. Conformity assessment is also linked to this technical documentation.
Companies therefore face a practical question: where do the required packaging data come from, and how are they kept up to date over time?
This is exactly where PakPruvo comes in as PPWR software.
What is technical documentation under the PPWR?
Technical documentation contains the information used to assess and verify the conformity of the packaging concerned.
It is therefore not the same as the EU declaration of conformity.
In short: technical documentation provides the basis. The declaration of conformity records the outcome of the conformity assessment.
Which packaging data matter for this?
Which particulars are required in practice depends on the packaging and the applicable PPWR requirement.
For a reliable data basis, packaging should not be maintained merely as a single record labelled “cardboard”, “plastic” or “glass”.
PakPruvo can therefore model packaging by component.
Each part can be described separately.
- Bottle
- Closure
- Label
- Outer carton
- Insert
Can materials and weights be documented?
Yes. PakPruvo can manage material and weight data per packaging component, among other things.
For example, you can capture:
- Bottle: glass, 145 g
- Closure: PP, 8 g
- Label: paper, 3 g
- Outer carton: cardboard, 22 g
Tare weights can also be stored in a structured way.
The information is therefore not gathered only when a document is created.
Can material compositions be captured?
Yes. A packaging component can consist of several materials.
PakPruvo therefore supports structured capture of materials and weight shares within a component.
That is especially relevant for more complex packaging constructions.
Example
A component consists of: 60% material A, 30% material B, 10% material C.
The composition can be assigned directly to the packaging part concerned.
Can recyclate shares also be recorded?
Yes. PakPruvo can capture recyclate shares in a structured way.
The PPWR includes requirements on the use of recycled plastics and further rules whose applicability and calculation depend on packaging type and the relevant implementing rules. The European Commission expressly describes higher use of recycled material as one of the central goals of the PPWR.
In PakPruvo, the data can already be assigned centrally to a material or packaging component today.
How are composite packaging structures represented?
A further capability covers the composite layer stack.
If a packaging component consists of several layers, that structure can be documented in a structured way.
A complex material build-up therefore does not have to be reduced to a single term such as “composite material”.
- Outer layer
- Adhesive
- Barrier layer
- Inner layer
Why does versioning matter for technical documentation?
Packaging does not always stay the same.
Suppliers change, materials are replaced, weights change, or a packaging build is adjusted.
PakPruvo therefore keeps versions and histories clearly separated.
An issued document can still be linked to the data state on which it was based.
From technical documentation to the declaration of conformity
Technical documentation and the declaration of conformity should therefore not be managed in separate data worlds.
PakPruvo connects: packaging record → packaging components → materials → documentation → review → declaration of conformity → version.
