CINCINNATI , March 15, 2010 (press release) – Michelman’s Michem® Flex Primers are water-based extrusion primers designed specifically for converters of flexible packaging substrates including paper, film and foil. The new Michem Flex P1852 grade produces strong adhesion between flexible substrates and extrusion coated polymer resins, with outstanding water resistance and broad chemical resistance.

Michem Flex P1852 contains no VOCs and requires no mixing. It can be applied on a single in-house coating station, and cures immediately upon application. Its performance is comparable to solvent-based primers, yet in a more environmentally friendly formulation. It will bond to resins extruded at low temperatures which minimizes odor and enhances heat seal.

All Michem Flex primers meet regulations for food packaging, and come as concentrated dispersions, minimizing shipping costs. They can be applied with smooth roll, flexo or gravure coaters and dried with hot, circulating air.

Michem Flex primers eliminate the need to stock specialty grades of pre-primed or pre-coated films. Converters can now stock less expensive, non-chemically treated film, and apply the coating on an as-needed, just-in-time basis.
