Abstract

The demand for hermoformable Polypropylene food container is rising. Polypropylene homopolymer does not offer high cold impact properties. The polypropylene copolymers offer better cold impact properties at the reduced crystallinity and hence the rigidity and top use temperature. In this article, an attempt was made to coextrude polypropylene with SIS core to achieve better cold impact strength. Cake-baking trays were thermoformed from these sheets. The wall thickness distributions of the trays were used to compare the thermoformability of these sheets.
