Sonoco's Patented Radial Crush Tester for Paper Tubes Made Available to Industry

Sonoco SON, one of the largest diversified global packaging companies, has reached an agreement with the Composite Can and Tube Institute (CCTI) to make the Company's patented Radial Crush Tester for spiral-wound paperboard tubes and cores available to the industry. According to David E. Rhodes, Sonoco's director of global industrial technology and engineering, “The radial crush tester measures the radial strength of a tube or core, which is a critical factor for a customer whose product applies a radial load such as plastic film and extensible textiles. The tester is able to simulate the loading condition that a customer's products apply to a core. The failure mode created by the tester is the same as the radial crush failure that occurs in a customer's winding operations.” Kristine Garland, Executive Vice President of the Composite Can and Tube Institute stated, “CCTI's Technical Committee will develop and publish a standardized industry-wide testing procedure for measuring radial crush with the Sonoco radial crush tester. The Radial Crush Tester will be demonstrated at CCTI's Spring Operations Meeting, March 16-17, 2011, in Myrtle Beach, S.C.” Sonoco developed the radial crush tester in response to customer requirements more than 15 years ago. The tester is manufactured exclusively by Sonoco and used throughout its global tube and core operations.
