Unless the printed layer is a barrier to migration and there is no possibility of set off to the unprinted (food contact) surface, SF*** ink series is not intended for food packaging specifications.
For applications where the material is not a barrier, or set off is possible, we recommend the use of Low Migration inks & varnishes. Contact us for further details.
It must also be mentioned that the Printer/Converter and Packer/ Filler has legal responsibility to ensure compliance with the relevant legislation for food packaging.

GUIDELINES FOR USE
Additives: Additives may be used to alter the ink properties to suit particular press conditions. Please contact the technical department for information or recommendations on reducers, flow aids and photoinitiators.
Thermal Printing: SF*** series is not suitable for printing on to thermal papers.
Laser Printing: SF*** series is not suitable for laser overprinting.
Thermal Transfer/Hot Foil Printing: SF*** series is not suitable for overprinting with thermal transfer. Hot foiling is possible but due to the wide variety of foils available should be fully evaluated prior to production runs.
Varnishes: SF*** may be varnished with any of our standard range of UV varnishes. Our technical department can provide advice for the best varnish for your application.
Cleaning: Equipment does not need to be cleaned immediately provided there is no exposure to sunlight. Ink should be cleaned with a UV wash such as RLA350 or suitable solvent such as Ethyl Acetate.
STORAGE & HANDLING
Store at temperatures between 50C and 250C. In unopened containers SF*** series inks have a shelf life of 12 months.
