Michelman. Cincinnatti, Ohio, USA, this week introduced Michem Flex P1883, a water-based extrusion primer that provides adhesion to aluminum foil and paper, bonds to extrusion coated resins, and protects foil from corrosion. The primer also provides chemical resistance to water, many acids, and spices, fragrances, and flavors. Because of its adhesive properties, it also helps prevent packages from delaminating when in contact with aggressive contents.

The new primer is ideal for applications including foil-based packages for condiments such as ketchup, mustard and salad dressings, soup and seasoning packets, dry milk powders, fruit juice powders, gummy candies, and virtually any type of paper/poly/foil/poly pouches or paper-based cans found on grocery shelves.

Michem Flex P1883 features 25% solids content and high freeze/thaw stability. The relatively high solid content means converters buy and shipping less water and more of the solids they need to achieve desired dry coat weights. It further reduces costs since it requires less drying time.

Michelman’s Michem Flex primers are water-based extrusion primers designed specifically for converters of flexible packaging substrates including paper, film, and foil. They 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.
