Polypropylene or PP (SPI code 4) is a thermoplastic polymer, and one of the many plastic bottle materials supplied by All American Containers Northeast. This plastic resin has a high melting point, which makes it very stable at high temperatures. As a result, it can be used for hot-fill liquids and can also be steam-sterilized. Although polypropylene is very resistant to chemicals, it loses some of its impact resistance at colder temperatures. But, the finished products allow for very low moisture transmission and good visual clarity.
Since Polypropylene creates a rigid packaging material which is resistant to heat, it is often used to create hard plastic jars and bottles for food and non-food items, bottle lids, and microwavable food containers. It is also used to create common plastic household goods such as garden rakes, bike racks, and rigid and semi-flexible storage containers. Polypropylene’s combination of rigidity and visual clarity allows containers to simultaneously protect and display their contents.
