Jemmco

What Jemmco does

Jemmco, LLC is a privately held industrial supplies company headquartered in Mequon, Wisconsin, founded in 1999 and operating as an LLC. The company manufactures and distributes specialized roller coverings, dyne test products, static elimination equipment, and web cleaning supplies for the film extrusion and web converting industries, with self-described market leadership in silicone treater sleeves across North America. Its product portfolio is organized under proprietary sub-brands including JemmTron (corona treater silicone sleeves, ceramic, and epoxy coverings), JemmTac (web cleaning sleeves, contact cleaners, and pre-sheeted adhesive rolls), JemmSil (high-release rubber sleeves and Teflon heat-shrink coverings), JemmTrac (traction sleeves and dimpled tapes), JemmStat (active and passive anti-static bars, cords, tinsels, and conductive sleeves), Accu-Flo and EZ-Read dyne pens, and complementary accessories such as JemmClean cleaning solutions and QMi perforation equipment.

The business model is predominantly direct-to-consumer e-commerce with quote-based custom manufacturing layered on top. Public-facing unit prices on consumables such as Accu-Flo dyne pens start as low as $4.60-$9.20 per pen with volume tiering, while custom roller coverings, corona treater equipment, and NEOS anti-static bars are sold via request-for-quote. Distribution combines a transactional website, an inside sales team (phone and email, M-F 8:30AM-4:30PM CST), and direct OEM fulfillment domestically and internationally, supplemented by trade show presence at ICE USA, Converters Expo, and Labelexpo. Customers span film extruders, web converters, printers, laminators, coaters, and plastic molders, with FDA-compliant options for indirect food contact on key sleeve products. Manufacturing is in-house at the expanded Mequon facility, supported by an external technical content library used as a top-of-funnel demand-generation channel.
