King Plastic

Founded in 1968, King Plastic Corporation began as a small family business and has grown into a leading manufacturer of quality polymer sheets, slabs and massive shapes. Operating from a state-of-the-art 250,000 square-foot facility in North Port, Florida, this American manufacturer has built a reputation for uncompromising quality and innovative polymer solutions that serve industries ranging from marine and construction to healthcare and food service.

Pioneering Innovation in Polymer Technology

King Plastic Corporation pioneered the first marine-grade polymer sheet, King StarBoard®, which remains the dominant brand in the marine industry today, and has since produced dozens of breakthrough products for a wide variety of industries, from food service to signage to giant slabs weighing more than 6,000 pounds. The company's proprietary K-Stran™ manufacturing process delivers superior flatness and consistency that sets industry standards for high-density polyethylene (HDPE) products.

What distinguishes King Plastic from other polymer manufacturers is their commitment to precision engineering. Quality is achieved and maintained through rigorous development testing, premium materials, tight tolerances, proprietary processes, thorough inspection, and careful shipping. These polymer sheets work like wood but offer distinct advantages: they won't rot, delaminate, or deteriorate when exposed to UV radiation, humidity, or water, making them ideal for demanding applications where traditional materials fail.

Premium Lumber/Polymer Solutions

King Plastic's polymer lumber products represent a breakthrough in construction and marine applications. These HDPE sheets combine the workability of traditional lumber with the durability of modern polymer technology. Fabricators appreciate that these materials can be cut, routed, drilled, and shaped using standard woodworking tools and techniques, yet they deliver lifetime performance without the maintenance requirements of wood. The polymer sheets are environmentally stabilized, marine-grade, food-safe, and CNC machinable, making them versatile solutions for outdoor cabinetry, furniture, architectural trim, and structural components.

Specialty Products and Exterior Decals

Products are purchased by companies that fabricate finished goods for many industries, including construction, manufacturing, healthcare, furniture, cabinetry and case goods, marine and RV, food service, playgrounds, signage, and more. Beyond their core polymer lumber offerings, King Plastic provides specialized solutions like exterior decals and signage materials that withstand harsh environmental conditions. The company's product portfolio includes over 20 branded product lines, each engineered for specific applications and performance requirements.

Built on American Quality Standards

King Plastic materials meet stringent industry standards and certifications, with products manufactured entirely from FDA and USDA approved materials where applicable. The King family remains privately owned and actively involved in the company, ensuring that the founding values of quality, innovation, and customer service continue to drive every aspect of the operation. This family commitment to excellence has earned King Plastic a loyal following among fabricators, contractors, and OEM manufacturers who demand reliable performance in their most challenging applications.

Whether you're outfitting a marine vessel, building outdoor structures, or creating antimicrobial surfaces for healthcare environments, King Plastic's American-made polymer solutions deliver the durability, workability, and long-term value that professionals trust.
