Sonoco Alcore


Which core is right for you?

In response to the evolution of highly advanced printing technologies and the introduction of unprecedented winding speeds and reel widths, Sonoco Alcore has developed a new generation of high-performance paper mill cores for the printing industry. M-Cores are proven to offer superior performance under the most demanding operating conditions due to their world-class straightness, bending stiffness and higher E-modulus values – even when compared with traditional high grade paper mill cores used in the printing industry.

The M-Core HT serves the needs of the high-end paper industry by delivering a core that offers reduced centre bursts and elongation during the winding/unwinding process.

Our Intellicore™ paper roll identification technology is a breakthrough, embedded core technology that enables automatic paper roll inventory tracking in areas of paper and paper-product manufacturing. The accuracy of Intellicore identification technology enables manufacturers to save significant money by reducing lost inventory and ghost waste, reducing the need for working capital and eliminating costly manual tracking during the life of a roll.

Linerboard producers now require a higher performance core due to changes in linerboard production as well as changes in the linerboard product. Some of these changes include:

  • Higher paper machine speed – Our M-Liner manufacturing process delivers a core with superior straightness and roundness for hassle free winding / unwinding.
  • More meters of linerboard are now wrapped on a core – M-Liner is designed using our industry leading Dynamic Strength Tester.
  • Increased Paper machine width (up to 10.8 meters) – Stiffness of the M-Liner reduces elongation which is a common issue when using double drum winders.
  • Lower tensile strength of the linerboard – The M-Liner manufacturing process guarantees a core with a smooth surface, no dents, or ply gaps to ensure the linerboard is undamaged during production.

Case Studies

Our Products at Work

Hi-Radius Core

Our Hi-Radius core has a smooth, rounded edge on the unwinding end, which allows the producer to avoid using plastic caps. This solution is especially effective if our customer is spinning and texturizing the yarn in-house.
