Equipment & Converting
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.
