RECOMMENDED IN-LINE CORKOTE BLISTER COATINGS
LITHO & FLEXO
CK-5791-26 is formulated for in-line litho wet trapping with coat weights of 0.50 lbs./MSF to 0.80 lbs./MSF(DRY).
CK-5791-26 is an aqueous , fast drying heat seal coating that has been formulated to provide effective fiber tearing properties for blister board card application. Usage: CORKOTE— 5791-26 is specifically designed to be applied one bump, inline, wet trapped over conventional wax free sheetfed offset litho blister pack inks. It has also demonstrated functionality when applied in-line over blister pack flexo or sheetfed offset UV inks. It is heat sealable to a variety of blister cell plastic films. Recommended single bump dry coat weight range is 0.50 lbs./MSF to 0.80 lbs./MSF(DRY).
These recommended single bump dry coat weights have been obtained using tower coaters and blanket coaters. Effective fiber tearing seals have been obtained when sealing PVC and other blister cells to recommended blister boards within standard heat sealing conditions of 350°F-375°F, 50-60 PSI, and 2-3 seconds dwell. Per usual, the longer temperature/pressure/time conditions are required when heavier pt. recommended blister board stocks are used.
CK-5791G is recommended for Flexo or Rotogravure Blister Applcation.
