Polypropylene is a thermoplastic that belongs to the polyolefin group of materials. Like most polyolefins, polypropylene is approved for direct food contact. Polypropylene offers a great combination of physical, chemical, mechanical, thermal, and electrical properties, with a good strength to weight ratio.

A nanocomposite containing polypropylene (PP) and nano α-Al 2 O 3 particles was prepared using a Haake internal mixer. Mechanical tests, such as tensile and flexural tests, showed that mechanical properties of the composite were enhanced by addition of nano α-Al 2 O 3 particles and dispersant agent to the polymer.
