Plastic Granules
Topilene® R301 Random Copolymer PP
Hyosung Topilene® R301 is a high-transparency polypropylene random copolymer. It is phthalate-free and food-contact compliant (FDA 21 CFR 177.1520, EU 10/2011). With 1.5 g/10 min MI, it processes easily for EBM bottles and thermoforming sheet. Low 30% haze delivers clear, premium-looking containers.
