1. A heat resistant ink or coating composition comprising resin, solvent and a heat resistant material comprising nylon particles, characterized in that application of the ink or coating composition on a plastic substrate, imparts the plastic substrate a feel of paper, wherein:
the nylon particles have a mean particle size of 30 μm to 100 μm;
a feel of paper is the haptic effect or tactile perception of touching and feeling paper;
the heat resistant material is not soluble in the resin and solvent;
the ink or coating composition does not degrade upon exposure to temperatures of 120° C. or greater; and
the feel of paper imparted by the coating is maintained after heat sealing or printing at temperatures greater than 120° C.
