CO₂ RE Foaming Technology

Foaming Technology for Dairy Packaging and the Food Service Industry

Styron LLC, Midland/USA, has announced the launch of CO₂ RE, a patented foaming technology aimed at helping the dairy packaging and food service industries reduce raw material consumption in packaging.

The technology allows converters to produce polystyrene sheet with a foamed core layer using physical blowing agents. The company internal tests using this foaming technology illustrate significant total density reductions of up to 20% with the potential to reduce density even further. By reducing polystyrene packaging density, it results in light weighting of packaging which benefits the entire value chain: converters use less raw material and energy to produce the packaging, while brand owners benefit from a lower packaging waste disposable tax. The lower the density, the higher the value extracted.

CO₂ RE foaming technology is available to license globally and can be implemented on existing lines at low cost. Although the technology was designed around the leading A-Tech polystyrene resins (same manufacturer), it also performs with other polystyrene resins - flexibility has been built into the license agreement in order for customers to maintain different sourcing options.
