A MONO- MATERIAL
RE-4 is a reinvented mono-material. With its foldable and hermetic properties in one mono-material, RE-4 can be adapted to most types of packaging, whether substituting cardboard, paper, plastic, aluminum, or a mix.
Refour is based on a revolutionizing formula consisting of air, minerals (talc and lime), and PP. Together, the resources form a mono-material that both reduces the use of industrial raw materials, while maintaining full recyclability and essential physical and mechanical properties.
By foaming air into the material, we guarantee an up to 42% lower material weight. This is not only a win for our planet’s resources, but also for our customers’ bottom lines. By cutting resource expenses we also cut costs.
In a recycling context RE-4 has, by EU regulated certification, been categorized as a mono material, seeing the concentration of the minerals doesn’t alter the regrinded PP or its density.
From the outset, it has been our mission to stop deforestation and protect biodiversity. This is why RE-4 contains no sort of wood fibers but instead natural minerals. Combined, minerals and PP are a fully circular substitute to all non-recyclable paper packaging.
Owing to its eco-intelligent formula where material choice, resource consumption, and disposal all have been equally taken into account, RE-4 has the lowest carbon footprint based on a thorough Life Cycle Assessment.
RE-4 is both strong and foldable thanks to the combination of minerals and PP. When combined, the minerals break down the PP’s memory feature, making the Refour material foldable. Supporting this, the PP binds the grinded minerals together, making it flexible so that it doesn’t break when folded.
RE-4 has excellent barrier properties, preventing air, moisture, and light from penetrating the material. The light transmission rate is as low as 0,4%. Likewise, RE-4 guarantees much better temperature insulation, eliminating the need for sleeves or double cupping.
RE-4 will open up an entirely new and extended world of quality printing on packaging, among others Flexo and HD Flexo. Additionally, we make it possible to use digital printing, and even adding 3D effects.
With its non-memory properties of paper and hermetic properties of plastic, RE-4 can be adapted to most types of packaging. As an example, an entire McDonald’s tray including straws, burger boxes, cups, etc. can be produced from RE-4, making the recycling process even more efficient and generate unprecedented positive impacts on the environment and corporate cost structures.
