Custom Converting for Filtration Media

Contract converting is the process of transforming roll stock into application-ready components through processes such as slitting, die cutting, sheeting, and laminating. Gremarco performs whichever steps you need. Many customers take slit rolls or cut pieces and complete the remaining assembly themselves or through another manufacturer, while others have us convert through to finished, retail-ready packaging.

Gremarco converts its own adsorbent filter media: nonwoven substrates, foams, and felts coated with one or more adsorbents, including activated carbon, silica gel, zeolite, activated alumina, and potassium permanganate. Composite media combining more than one adsorbent are also available.

Converting options include die cutting, slitting, sheeting, custom laminates, and roll goods. Packaging options include bulk, retail, custom, and individually bagged formats, with accessories such as Velcro tabs, plastic clips, clip strip mounts, printed polybags, and printed packaging.

Gremarco converts media for air filtration systems, industrial gas purification, environmental control systems, HVAC filtration, chemical processing, OEM manufacturing, and medical and laboratory filtration.

Yes. Gremarco supports prototype development through full production volumes, so you can validate a design before committing to a production run. Minimum quantities vary by material and converting process — contact us with your specifications and we will confirm what is required.

Gremarco manufactures the adsorbent media it converts, so material behavior and converting are handled by the same team rather than split between a media supplier and a separate converter. That means substrate compatibility, carbon loading, and cut tolerances are considered together. Our equipment is versatile and accurate, and we deliver quickly and on time.
