.020” Pulp FS 3-19 Heat Induction Foil Innerseal Composition
is a tough plastic that has a good chemical resistant. PP is translucent in its natural state but can have a glossy finish when produced with color. Some examples of common products with PP are dairy and medication containers. Polypropylene is suitable for hot fill applications of up to 165°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.
