Equipment

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.

Capacity

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.
