A blister package is defined for retaining product. The package is formed from a receptacle substrate having a planer sealing flange and at least one receptacle hollow for retaining product therein. A top layer is provided, covering the receptacle hollow with a portion overlapping and sealed to the sealing flange. A score pattern is formed in the top layer for promoting propagation of a tear upon forcing product from receptacle hollow against the top layer. The score pattern is defined by a plurality of rows of parallel straight lines aligned with the receptacle hollow. In addition, a plurality of spaced curved or bowed score lines are provided. The curved or bowed score lines transversely intersect the rows of straight lines above the receptacle hollow.
