By using Mondo Minerals´ talc, polystyrene in food packaging can be replaced by polypropylene talc compounds. This increases the stiffness, which allows for wall size reduction. At the same time, the flexibility remains better than that of polystyrene, so yoghurt cups don´t crack if they fall on your kitchen floor.
Also in microwave trays, talc is used in the form of PET compounds. Again, mechanical properties are improved while polymer consumption, carbon dioxide emission and polymer consumption are reduced.
