5 Reasons to Use Calcium Carbonate Filled Polypropylene

Calcium Carbonate (CaCO 3) is one of the most widely used mineral fillers in the plastics industry, and its use in rigid packaging has increased significantly over the years Once thought of simply as a resin extender, the addition of calcium carbonate in plastics has been shown to contribute to increased performance, improved processing, and improved sustainability of the finished partBarrier properties The addition of calcium carbonate to polyolefin films also improves barrier performance Improved barrier allows processors the ability to downgauge and maintain barri er properties, or improve barrier characteristics at theThe Use of Calcium Carbonate in Polyolefins OffersIn this study, the potentiality of biodegradable barrier films prepared from polyvinyl alcohol (PVA) and calcium carbonate (CaCO 3) nanoparticles has been examined at different pressures and temperatures for film packaging applicationsFor this purpose, CaCO 3 nanoparticles, synthesized through a reverse microemulsion route, were loaded into PVA by dint of solution castingProperties investigation of polyvinyl alcohol barrier
