UV curable ink used on PE materials was developed. The influence of prepolymer, monomer and photoinitiator on the UV ink properties such as curing speed, adhesion and solvent resistance were discussed. The optimum formulation of the UV curing ink was as follow: PUA is 25%, PEA is 25%, TMPTA is 15%, NPGDA is 15%, TPO is 5%, carbon soot is 12%, defoamer is 4%, and dispersant is 4%. Under this condition, the UV curing ink properties were as follow: curing time 8s, adhesion level 3 and good solvent resistance. It was concluded that the UV curing ink is suitable for printing on PE substrates.
