Polypropylene PlasticPolypropylene (PP) is a tough plastic that has excellent chemical resistance. PP is translucent in its natural state but can have a glossy finish when produced with color. Some examples of common products made with PP are dairy and medication containers. Polypropylene is suitable for hot fill applications of up to 205°F and is therefore great for autoclaving. It is not recommended for cold or sub-freezing temperatures. The Cary Company has an assortment of polypropylene plastics available for purchase, such as plastic caps and jars, which have a higher tolerance for chemical products. Discover if Polypropylene is appropriate for hot fill application by learning more about What Is Hot Fill Packaging and how it applies to Polypropylene containers.
