RDM Group, a producer of recycled cartonboard, has introduced Multiboard Barrier, a polyethylene-coated cartonboard designed to meet performance demands while tackling environmental issues.

The new product aims to provide a sustainable solution for various packaging needs.

The company highlighted that its PE-coated boards are suitable for hygroscopic products, which require moisture protection.

Its applications include packaging for frozen food items, such as fish and cakes, as well as pet food boxes.

RDM Group claims that its paper-based products significantly reduce the plastic content in high-performance packaging.

The PE layer in the Multiboard Barrier can be as thin as 3-5% of the overall structure, depending on the chosen grammage and coating, the company added.

The thermoplastic nature of polyethylene offers heat sealability, allowing the board to function as a “hot glue.”

This feature provides an advantage over non-heat sealable alternatives that rely on adhesive-based lamination, which complicates recycling efforts, according to the company.

Manufactured at RDM Group’s Fiskeby mill in Sweden, the Multiboard Barrier is made with 100% recycled fibres.

It is claimed to be fully recyclable and can be processed alongside other paper-based products, boasting a recycling rate of 83%, more than twice the rate of plastic packaging.

The Multiboard Barrier is claimed to align with the EU’s Packaging and Packaging Waste Regulation (PPWR).

RDM Group chief innovation and sustainability officer Krzysztof Krajewski was quoted by various media houses as saying: “At RDM Group, we believe that rethinking plastic for today’s world doesn’t mean eliminating it, but using it in a smarter more circular way.

“Multiboard Barrier is a solution that integrates minimal plastic use into a fibre-based board structure, optimising both functionality and recyclability.”
