About King Plastic Corporation

Since 1968, King Plastic Corporation has built a reputation as one of America's foremost manufacturers of high-density polyethylene (HDPE) and polymer sheet materials. What began as a modest family enterprise in Florida has grown into a globally recognized brand, operating out of a 250,000-square-foot state-of-the-art facility in North Port, Florida, with a distribution center in Medford, Oregon — all while remaining privately owned and family operated.

King Plastic's most celebrated innovation is King StarBoard®, the original marine-grade HDPE sheet. Developed using the company's proprietary K-Stran™ manufacturing process, King StarBoard® delivers exceptional flatness, dimensional consistency, and resistance to UV, moisture, and delamination — qualities that have made it the dominant choice in the marine industry for over three decades. It was the first product of its kind, and it remains the benchmark against which others are measured.

But King Plastic's reach extends well beyond the water. Their extensive plastic sheeting lineup serves industries including food service, healthcare, signage, parks and recreation, retail display, and industrial fabrication. Products like King MediGrade® bring advanced antimicrobial technology to hospital and clinical environments, while King ColorCore® and King ColorBoard® open up design-forward applications in architectural and retail settings. Every sheet in the King catalog is engineered for demanding real-world use — resistant to staining, odor, and the elements — without ever needing painting, sealing, or refinishing.

One of King Plastic's most compelling selling points is how naturally their materials replace traditional wood. Their lumber and polymer products are fabricated using standard woodworking tools — saws, routers, CNC machines — making them an approachable choice for builders, boat fabricators, and craftspeople who want the workability of wood without the vulnerabilities of rot, swelling, or splintering. Products like King StarBoard® WG even replicate the visual texture of wood grain, bringing aesthetic appeal alongside industrial-grade toughness.

With over 20 distinct product brands and a worldwide distributor network, King Plastic continues to push the boundaries of polymer innovation. Whether you're outfitting a boat, designing a food-safe workspace, or sourcing materials for an architectural project, King Plastic offers a solution engineered to last — and backed by more than five decades of American manufacturing heritage.
