Coaters & Laminators

Coating and laminating create the core of our business. At Sierra Coating Technologies, we operate three different coating machines. These coating machines are used in our made-to-order manufacturing, contract and toll manufacturing, and product development services.

  • Two 62-inch coaters with wet and dry lamination capabilities
    • Gravure, offset, and slot die coating as primary methods
    • Two-zone flotation drying method
    • Product coating width between 25 inches and 62 inches
    • Roll outside diameter of up to 60 inches (weighing up to 3,500 pounds)
  • One 47-inch hot melt coater with lamination capabilities
    • Gravure – two roll offset as primary method
    • Roll outside diameter of up to 50 inches

This equipment can accommodate material rolls with core sizes of 3, 4, 6, 8, or 12 inches. Finished products can be delivered in any of the following formats:

  • On the master roll
  • In small slit rolls
