Abstract: The invention is directed to a lidding material that can be used in blister packaging and the like. In particular, the invention is directed to a lidding material for blister packaging comprising a base paper on which is present a pre-barrier layer and a latex coating, wherein the pre-barrier layer is present between the base paper and the latex coating, wherein the lidding material has a Mullen burst strength between 80 and 200 k Pa, as defined by ISO standard 2758, a tear strength between 100 and 400 m N, as defined by ISO standard 1974, and a water vapor transmission rate of ?4 g/m 2/day (determined at a temperature of 38° C. and at a relative humidity of 100%, as defined by ASTM F1249), and wherein the lidding material optionally further comprises a sealant layer adjacent to the latex coating.
