Heat sealable emulsion coating, developed to produce ready to use blister cards from a single machine printing pass. Suitable for most common blister films, i.e. PVC, PET/A, and PET/G, although different seal profiles will be required for each film type. Specially selected boards suitable for waterbased blister coating must be used. TWGW1120 seals at an interface temperature of 100°C to 180°C dependent on the blister film used.
