Paper Mill Cores

Improve runnability, productivity and safety during core-cutting and converting. Sonoco works with machine manufacturers to create proper containerboard core designs that deliver the straightness needed on new faster, more automated equipment. Preventing costly core chewout, slippage, failure and loss of web tension control, our Torque Transmission or T2 enhanced cores: 

• Minimize core chewout and spinout
• Reuse cores more readily
• Improve torque resistance up to 100%
• Reduce vibration and web breaks that occur during splicing
• Eliminate waste with fewer starts and stops 

Match your specific strength and performance needs. Sonoco designs shrink film cores to eliminate radial pressure and protect the internal diameter integrity, protecting from chewout, core length growth and other damage. Designed for efficient winding and unwinding, our cores streamline your manufacturing process and decrease manual labor costs. 

Reduce costs with a full range of customizable cores. Designed for unique applications, Sonoco’s paperboard cores provide high-quality solutions for linerboard and bleached board applications. 

Improve operations with tissue and towel cores known for consistent quality. Sonoco engineers cores with proprietary paperboards, adhesives and coatings to carry products during converting. With the ability and industry knowledge to customize unique features, we design a complete range of cores from high performance, large-diameter, reusable parent cores to small, cost-efficient, lightweight cores. 

To support your processes, specifications, characteristics and performance criteria, we offer services and conduct regular audits that include: 

• Converting chuck audits
• Finite element analysis of master roll package
• Core recutting and regrading programs
• Radio-frequence identification (RFID) tracking 

Decrease your total costs with Sonoco. We produce quality cores for rolled pulp and nonwoven materials. With a range of core sizes and features, we design pulp and nonwoven products to meet your specific application and decrease costs. 

Combine exceptional experience and technology with Sonoco. We produce cores for newsprint and direct grade applications with a variety of special end finishing options—metal ends, metal inserts, notching and beveled cores.
