Hot melt coating involves heating and melting organic compounds such as asphalt, paraffin, polyethylene, polypropylene, polyethylene terephthalate, and polyacrylic acid resins into a liquid, and then coating the substrate.
The coating is carried out in an adiabatic state, and the finishing is measured with blade. The coated paper web is cooled by a cooler or a cold cylinder; The molten coating is formed on the substrate to form coating. And the coating is rolled and processed into finished products.
