At Sierra Coating Technologies, our equipment is specialized for exacting applications. Our commitment is to apply coatings to meet product specific coating weights with the best tolerances. This means that Sierra® has different coating methods to suit individual coating and application coating needs.

We can accommodate a wide range of material, from .48 gauge films and nonwovens to heavyweight papers and liner board up to 40 pt. board.

Sierra® provides comprehensive coating and lamination solutions using three coater/laminators. Two coaters are equipped with flotation drying and can perform laminations before or after the drying ovens and hot melt coating line.


One of the basic questions we receive is: Does Sierra have enough capacity for our project?

Sierra runs its business with very large amounts of excess machine capacity.

This is intentional for a number of reasons:

  • To provide the level of customer service required by making a number of branded products
  • To provide capacity for new products and filling supply chains at start up
  • To have back up if one machine were to need repair

Sierra’s business it to provide capital equipment and labor on a variable cost basis to make customer product to high quality standards within defined delivery periods.

Coater Capacity:

Sierra has three coaters. At a standard average speed the Sierra facility can process at current staffing over 800 million square feet of product annually. With increases in staffing to work a 7-day schedule, the facility can process approximately 1.6 billion square feet of product.
