Back to Basics

Sonoco (Hartsville, S.C.) produces cores made of fiber, plastic, and composite materials, and are designed to meet customer needs in a wide range of markets, including the film market. Its high-performance film cores series, The Millennium Series™, is designed with a range of surface qualities and characteristics engineered to minimize surface markings, and improve winding and unwinding. Sonoco takes note that for many types of films and foils, there is a strong correlation between the surface of the core and the amount of scrap generated.
