摘要

The printing plate, for flexographic printing, has a carrier, a relief layer, and an optional covering film. The carrier is of a micro-cellular polyurethane elastomer material with a density of 200-1100 kg/m3. The carrier has a residual pressure distortion of at most25%, a tensile strength of at least2 N/mm2, a stretch of at least300% and a further shear strength of at least8 N/mm2.
