Polypropylene is a plastic polymer with the chemical formula C3H6. It is used in many different settings, both in industry and in consumer goods, and it can be used both as a structural plastic and as a fiber.This plastic is often used for food containers, particularly those that need to be dishwasher safe.lastics such as polypropylene and polyethylente can be made to biodegrade in landfills, if an additive is put into them at the time of manufacture. In landfills, it contributes to methane capture, which saves the equivalent to the fuel used in 14 million cars a year.
