The present invention describes a flexible laminate suitable for use in packaging applications comprising a thermoplastic first substrate laminated to a second substrate. The thermoplastic first substrate includes a first exterior surface and an opposing second exterior surface, at least a first polymeric layer comprising a plurality of anti-block particles. The thermoplastic first substrate has a total thickness of A, the plurality of anti-block particles have a mean particles size, B and a distribution of particle diameters, C. Mean particles size, B and distribution of particle diameters, C are such that either B, or at least 10% of C, is at least 31 microns. The relative values of A, B, and C are such that they satisfy at least one of the following relationships AB <= 1.0 or A/C <= 1Ø
