Polypropylene (PP) is a common type of plastic material, with its chemical structure formed by the polymerization of propylene monomers.

It boasts several excellent characteristics such as high melting and melting point temperatures, good tensile strength and rigidity, and lower density, making it a preferred choice in various fields including packaging, food containers, medical devices, automotive components, and more.

However, like other plastics, PP also poses environmental challenges, particularly pollution and energy consumption during processing and disposal. Therefore, for sustainability and environmental protection, proper use and recycling of PP are crucial.
