New Stealth Core film core

Sonoco’s new Stealth Core film core with active tension displacement (ATD) technology is currently available for use with machine-grade stretch film.

New faster converting equipment and improved resin technology has enabled film manufacturers to make thinner, high-quality film, which can be wound around a core more times as it becomes thinner.

Each layer of film wound on a core adds more pressure to the core structure.

Traditionally, film cores have been strengthened by using stronger paper and adding layers to the core structure.

The Stealth Core film core's design dissipates radial pressures by actively dispersing it in compound directions, protecting the core's internal diameter (ID) integrity and reducing core length growth, during and after the winding process.

The film cores are designed to fit seamlessly on existing equipment for effortless systems integration.
