Polypropylene is cherished for its heat resistance, tensile strength, toughness, flexibility, and resistance to fatigue (constant bending) as a thermoplastic polymer. Chemicals cannot leach from it, making it one of the safest plastics. Microwaveable kitchenware, yoghurt containers, and baby bottles contain it.
A popular plastic material, Polypropylene is used around the globe. In addition to packaging, equipment, electrical, household appliances, and automotive manufacturing, it has spread widely since 1957. The amount of PP produced today is around 55 million metric tons per year.
Because Polypropylene is unlikely to leach any chemicals into foods or beverages that it might contain, it has been hailed as being extremely safe. In addition, the high heat resistance of the material makes it a good choice for applications involving heat (such as the microwave).
This material is commonly found on grocery store shelves due to its food safety rating, heat resistance, and flexibility. We find this interesting feature on many bottles and containers called a “living hinge” in the condiments industry. You won’t lose the lid while opening or closing them!
