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.
