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.
