ReFoam and RePaper
– our sustainable packaging solutions

As a company with an innovative and forward-looking focus, Wetropa always acts with sustainability in mind. For example, we have been climate-linked since 2019 and invest around 5% of our turnover in sustainable development, with material-oriented solutions such as ReFoam and RePaper playing a key role.

The idea behind ReFoam

Setting new standards is our goal. We have implemented our requirement to develop a sustainable product range with ReFoam.

Wetropa’s ReFoam products are made from sustainable foams, which are mono-materials that are unmixed and fully recyclable in a closed loop. Some recycled materials are used in the production of the materials. As a medium-sized company, we are committed to offering the greatest possible transparency, acting responsibly and building long-term partnerships that are characterized by quality and service.

100% recyclable foam

Our ReFoam packaging is made from sustainable foams that are mono-materials, single-origin and fully recyclable.


Our ReFoam packaging is durable and can be reused.

Conserving resources by saving CO2

By continuously improving processes and optimizing the use of materials, we already take resource-saving use into account when developing our foam packaging.

Circular economy through foam recycling

Packaging waste is first roughly shredded in our in-house plant and pressed into bales before being pressed into regranulate in a special plant. This regranulate can be 100% reintroduced into the production cycle for PE foam.

A convincing solution with a diverse ReFoam product range

The materials from the Wetropa Group’s ReFoam product range cover numerous material properties and applications. As many of our packaging materials are fully recyclable and contain a recycled content, there is a large selection of sustainable foams for packaging solutions.

With the ReFoam materials, the Wetropa Group is setting standards in the field of sustainable foam packaging. If you are interested in the versatile, highly functional and sustainable materials ARPLANK, Stratocell, Ethafoam, Synergy, Synergy Prime and Whisper, please contact our team of experts. We look forward to your inquiry.

From Arplank to Whisper – ReFoam materials at a glance

The Wetropa Group’s ReFoam series includes various sustainable foams for a wide range of applications. All materials are characterized by the combination of outstanding functional material properties and sustainability according to the principles of Reduce, Reuse and Recycle.



ARPLANK is a closed-cell foam made of expanded polyethylene (EPE), which is characterized by excellent shock absorption and high elasticity with full recovery.

ReFoam stands for:


Pure recycling

ReFoam products from Wetropa are sustainable foams which, as mono-materials, are single-origin and fully recyclable. In some cases, recycled material is already used in the production of the materials.

Delivery also works, thanks in part to our locations, which are distributed throughout Germany and therefore enable us to have short supply chains of less than 1,000 km. As we at Wetropa are convinced of the functional performance and ecological impact of ReFoam foams, we only use these products as raw materials when developing new packaging solutions.

We also actively promote the development of new sustainable materials through close cooperation with our suppliers and producers. Last but not least, we offer a take-back service for ReFoam packaging so that it can be professionally recycled and returned to the material cycle as recyclate.
