A UV Curable Grease Resistant Coating Comprised of GRAS Components

摘要

There has been a continuing concern in the UV curable community to develop materials that might safely be used in contact with food. The RadTech Food Contact Alliance has addressed this problem through FCN 772. However, coatings, inks and adhesives so formulated are permitted a migration level for each monomer or photoinitiator of up to 1 ppm. The total level of nonvolatile extractables from a finished coating may not exceed lppm after correction for migration levels of whatever monomer or photoinitiator was included in the formulation. The specified UV and EB cured coatings and inks may be used in direct contact with food, subject to these requirements. FCN 772 does not apply to everyuser of these materials. Under FDA regulations, only members of the Alliance and their customers may claim clearance for materials and or formulations covered under FCN 772. Many businesses may find these requirements difficult to meet. Coatings created from foodstuff materials that are generally regarded as safe (GRAS) under 21 CFR 175 would create no such difficulties.
