Sealed Charts and Cards for Coatings Tests

Leneta sealed charts are made from high quality, 14 mil thick, coated 2 side paperboard and Leneta sealed cards are made from 20 mil thick, coated one side paperboard with greater rigidity for more convenient handling. Both products are sealed with a 100% solids clear UV topcoat which prevents applied coatings from penetrating into the paper. The paper contains no optical brighteners which can affect instrumental color measurements.
