Strengthen Your Inner Core

Sonoco’s high-quality, precision-engineered plastic filter components are designed to meet the strict regulations of the liquid, air and medical filtration markets.


Our wide assortment of plastic filtration cores combines superior structural strength, chemical resistance and thermal stability attributes to meet the most demanding requirements. The basic design incorporates the use of longitudinal and radial ribs engineered to furnish high collapse strength. A stipple finish on the core aids in retention of the initial placement of fibers.

In addition to cores, we offer all components required for plastic filter cartridges including cages, adaptors and endcaps. Our plastic filter components are available in engineered resins that are highly resistant to chemical attack from both acidic and alkaline substances
