Six major consumer goods companies have joined the PaperFlex Consortium to develop paper-based alternatives to small plastic sachets, wrappers and pouches, in a collaboration announced on 16 September.
Colgate-Palmolive, Mars, Nestlé, PepsiCo, Procter & Gamble and Unilever are the founding members. The Ellen MacArthur Foundation convened the group, with support from (RE)SET.
The Foundation’s announcement sets out plans for shared research into biodegradable coatings, coating technologies and the performance of paper materials on manufacturing lines.
Its focus is on markets where formal collection and recycling infrastructure is limited. The aim is to develop packaging that can be recycled as collection improves and can biodegrade if it unintentionally escapes into the environment.
This is a research initiative, rather than an announcement that the six companies are replacing their existing packaging ranges. Members will continue to make their own packaging decisions independently.
For supermarket suppliers, the challenge extends beyond changing the material visible on a shelf. Packaging must protect products, preserve shelf life and run reliably through filling and sealing equipment.
In an earlier technical overview, the Foundation said paper alternatives can cost more and run more slowly on existing filling lines than plastic. Coatings and barriers needed for moisture or grease resistance can also complicate recyclability and biodegradability.
That makes performance and cost central to the collaboration. A material that works in a laboratory still needs to meet food manufacturers’ production requirements and retailers’ expectations for safe, durable packs.
The consortium is guided by six design criteria covering responsible sourcing and production, commercial and technical suitability, local recyclability, chemical safety and a wider circular economy approach. Paper substitution alone does not remove the need for collection systems or responsible fibre sourcing.
Other FMCG companies can apply to join through the PaperFlex Consortium. The next step is collaborative trials; the launch announcement did not set a date for a shared commercial product rollout.
