Packaging laminates containing anti-block particles

A flexible laminate suitable for use in packaging applications comprising:

• a) a thermoplastic first substrate having a first exterior surface and an opposing second exterior surface, and a total thickness of A;
• wherein thermoplastic first substrate comprises at least a first polymeric layer comprising a heat-sealable resin or blends thereof;
• b) a second substrate comprising at least a first layer;
• wherein said thermoplastic first substrate is extrusion coated onto said first layer of said second substrate;
• c) wherein said first polymeric layer of said thermoplastic first substrate comprises a plurality of anti-block particles dispersed therein;
• wherein said plurality of anti-block particles have a diameter that is at least equal to or greater than said total thickness of said thermoplastic first substrate and are present in an amount such that a portion of said plurality of anti-block particles protrudes said first exterior surface of said thermoplastic first laminate;
• d) wherein said plurality of anti-block particles have a mean particle diameter B, and a distribution of particle diameters C, such that either B or at least 10% of C, is at least 31 microns (0.0031 cm) as measured in accordance ASTM D-4464 test method;
• and
• e) wherein said total thickness A, said mean particle diameter B, and said at least 10% of said distribution of particle diameters C, are such that the relative values of A, B and C satisfy at least one of the following relationships A/B≦1.0 or A/C≦1.0.
