An extrusion-coated lidding foil for blister packaging particularly suitable for push-through pharmaceutical and food blister packaging. The lidding foil includes a foil layer on which one or more tie layer and one or more sealant layer, one or both of which include an embrittling agent mixed therein, are extrusion coated resulting in a lidding foil having push-through ability. The push-through ability of the lidding foil is characterized by a Mullen burst strength of about 10 psi to about 30 psi and an MD tear strength of about 30 to about 100 grams-force.
