King KPC LDPE is a low-density polyethylene material. It is the product of a proprietary process called K-Stran™, the most advanced manufacturing process for superior flatness and consistency for gauges up to 1-1/2” thick. Larger gauges up to 4” thick are manufactured in our state-of-the-art compression mold or extrusion mold. King KPC LDPE has a natural, smooth gloss finish on both sides of the sheet. It is extremely versatile with outstanding properties and good chemical resistance making it ideal for a wide variety of applications such as stencils, orthopedics, packaging, sound deadening, and the automotive applications. Other applications may include trays, general-purpose containers, food storage, laboratory containers, and corrosion-resistant work surfaces. King KPC LDPE natural is FDA and USDA approved material that can be used for food containers and food equipment. * It is ideal for applications where corrosion resistance is a factor, but stiffness, high temperatures and structural strength are not. The material is easy to machine and fabricate.
