What Corona Supplies does

Corona Supplies Ltd is a Thame, UK-based private limited company and the only UK manufacturer of corona treatment equipment, founded in 2005 by former Sherman Treaters employees. The company designs, manufactures, and services corona treater systems, power supplies (CS 6000, CSR, and CSR+ Series at 0.3-20kW), ozone destruct units, dielectric components, and a newly launched Standalone Sheet Treater for sheet processing up to B1 size. Underlying technology applies high-frequency (9-50kHz), high-voltage (up to 30kV) signals across air gaps or dielectric barriers to ionize air and raise surface energy on plastic films, coatings, and printable substrates, improving ink, coating, and adhesive adhesion.

The company generates revenue across five streams: one-time equipment sales of bespoke corona treaters, spares and consumables (dyne test pens, inks, silicone sleeves, ceramic electrodes), technical service and refurbishment, official supply of Sherman Treaters legacy products and OEM spare parts, and upgrades of legacy Sherman Treaters stations and generators. Distribution is direct-sales led with on-site service capability worldwide. End customers are industrial manufacturers in plastic film extrusion, conversion, narrow web and digital printing, sheet-fed printing, and film production.

The business model relies on a small specialist team (11-50 employees) with over 50 years of combined technical experience inherited from Sherman Treaters. Corona Supplies holds an exclusive position as the only qualified servicer of the legacy Sherman Treaters installed base, providing a defensive moat around an aging but durable equipment footprint. Marketing is technical and documentation-driven rather than consumer-facing, with brochures and manuals in multiple European and Latin American languages supporting international reach.
