An international project has been launched to develop and bring paper-based flexible packaging to market in order to reduce marine pollution from small flexible packaging. Cumulative leakage into the ocean by 2040 could reach 20 trillion items, according to estimates.
The Ellen MacArthur Foundation announced the launch of a multiyear project to develop and bring paper-based flexible packaging to market. Builders Vision Philanthropy and the Minderoo Foundation are collaborating on the project, which will involve preparing a technology roadmap, mobilising funding and advocating for policy measures.
Small flexible packaging is lightweight and convenient to use, but difficult to collect and recycle, and is considered a major source of marine pollution. The initiative aims to strengthen collaboration to commercialise paper-based flexible packaging and expand its market.
In a report published in spring 2026, the foundation pointed out that collection rates for small plastic flexible packaging are low worldwide and that a high proportion enters the ocean. Paper-based alternatives are viewed as promising in terms of recyclability and biodegradability, but challenges remain before they can be commercialised.
The PaperFlex Consortium was launched in advance, with major companies including Nestlé, Mars, Unilever, P&G, Colgate-Palmolive and PepsiCo participating. The initiative aims to promote the market rollout of innovative materials through the development of responsible design standards, cost reductions and regulatory compliance.
