Film Cores

Our proprietary RCS® technology was developed specifically for the industrial stretch film market and is one of the only products tested to meet radial crush strength specifications among every size range available. Using our unique RCS® paperboard, we’re able to offer you a core that can withstand the radial pressures of curing film using less fiber, offering you superior performance and a reduced manufacturing cost, all while consistently delivering the results your end users expect.

For superior performance in hi-tech manufacturing and technology applications, Sonoco’s industry-leading cores offer the defect-free surface necessary to ensure product integrity. These specially designed cores offer maximum dimensional stability, straightness and smoothness, reducing your risk of wrinkles, warpage, and film deformation. Your high-value products deserve a core that will increase your film yields and your speed-to-market while protecting your assets all the way to end user application.

Sonoco not only understands your manufacturing lines, your materials and your operating environments, we’re able to optimize our film cores to meet your exact specifications. Only Sonoco has the level of supply chain security, in-house research and testing, and consistent quality to claim the role of industry leader for packaging film cores.

From cutting-edge geomembranes for agricultural solutions to industrial bag liners, disposable medical films, and BOPP films, there are a wide range of custom films that have their own unique set of market specifications, environmental hazards, and transportation/storage challenges. Sonoco understands how these markets are able to customize film cores for these specialty and custom applications.
