PP rigid packaging modified with the New Granic - the latest sustainable alternative to PS
There is a big concern in the thermoforming market on PS use for food packaging. Many developments have been launched in order to find a feasible substitution for this polymer in the last years, the main reason being the repeatedly reported residual styrene monomer migration from packaging to content. In addition, polystyrene’s high brittleness, its relatively high density & high cost, together with its low recyclability is pushing many to find alternatives.
However, PS is a stiff material with good processability and thermoformability, which makes it a long-lasting and hardly replaceable material for food packaging.
Granic’s new development provides an innovative solution to replace PS. Combining a high lamilarity talc with a special matrix, it achieves similar performance to PS for rigid packaging.
The perfect synergy found between the different components of this new grade makes snappable PP achievable. Moreover, this product keeps the sorting streams unaltered as PP’s density is maintained below 1g/cm3.
Replacing PS by PP + Granic brings along important savings in CO2 emissions, what makes it an optimal choice in terms of environment.
