EFT has the capability to analyze the physical properties of cellulosic and synthetic fiber based paper products. We provide the services to conduct refining studies, construct variable basis weight, variable density handsheets, and analyze the handsheets for mechanical properties.

Our 12" x 12" handsheets are heavier than TAPPI Standard Handsheets (60 g/m²). Strength rankings of pulp/paper made at 60 g/m² may differ when basis weights are higher. Higher basis weight testing may correlate more closely with the final end use requirements of the product.
