Single pass radiation curable inkjet printing methods for producing printed flexible foils and plastic bags

摘要

A radiation curable inkjet printing method for producing printed flexible foils and plastic bags wherein a web-like polymeric substrate having a maximum value for Tan δ between 40° C. and 110° C. and a surface energy S_sub is printed upon using a single pass inkjet printer with a non-aqueous radiation curable inkjet liquid having a surface tension S_Liq, wherein S_Liq is smaller than S_sub by at least 4 mN/m, and curing the radiation curable liquid on the substrate at a surface temperature equal or higher than the temperature of the maximum value for Tan δ and smaller than the melting point of the polymeric recording medium. A single pass inkjet printer is also disclosed.
