As one of the world's most widely used food-contact plastics, Food Grade PP Pellets offer an outstanding combination of safety, cost efficiency, processability, chemical resistance, and recyclability. These specialized pellets are extensively employed in food containers, packaging films, bottle caps, meal boxes, yogurt cups, microwave-safe tableware, and numerous other applications where material safety and performance are paramount.
To meet diverse food packaging requirements-including high-temperature sterilization, transparent display, airtight preservation, and microwave heating-standard PP undergoes systematic modification to enhance specific properties. The selection of Food Grade PP Pellets is driven by their superior food safety, excellent chemical resistance, lightweight nature, outstanding recyclability, and competitive cost. While conventional PP has a heat deflection temperature of approximately 100–110°C, making it unsuitable for high-temperature retort or microwave applications without modification, advanced formulations overcome these limitations, transforming PP from a "general-purpose packaging material" into a versatile solution capable of handling cold and hot, dry and moist, rigid and flexible, as well as transparent and opaque packaging scenarios.
