A child-resistant blister package that is also easily opened by adults. The package includes a formed blister film and a lidstock having at least four layers: i) an inner thermoplastic heat sealable layer; ii) a first intermediate aluminum foil layer; iii) a second intermediate adhesive layer; and iv) an outer layer having a loop shaped score line therethrough. The formed blister film has at least two compartments: (i) a first blister compartment adapted for receiving a product (a); and (ii) a second blister compartment adapted for manual inward deformation activation of separation of the lidstock from itself along a score line tab area portion.
