Extrusion Coating Primers

Michem® Flex P-series primers render packaging films and papers more receptive to extruded PE and PP film, thus the extrusion process is more efficient at lower temperatures, and the extrudate has better adhesion to the substrate. Available primer grades are optimized for applications ranging from very demanding retort packages to more basic end uses.
