Hot Melt Thickness Measurement with the MCT360 Gauge for Paper, Film, and Foil
Paraffin Wax is largely accepted as the first hot melt coating application. Polymer and copolymer resins brought a host of formulations for improved performance properties that continue to expand the horizons of Hot Melt applications.
Roll Coaters, Die Coaters, extruders, and doctor blade configurations are among the methods of applying hot melt adhesive. Roll coaters offer more flexibility than die application methods as they change over more quickly and allow for stripe coating. Die Coaters offer more precision across the web, especially in the 15 to 20 GSM. Hot melt applications of 100 GSM are very common and the range can go from 0-400 GSM.
