Easy opening blister-type packaging unit (1) having upper and lower walls (2, 2') and a convenient tear-open strip (5, 6, 7) inward of a peripheral seal (4) joining the walls to one another, and method of separating the seal from the blister pack to access a stored article, such as a razor set (16). Packaging unit (1) has upper and lower walls sealed together at peripheral joint (4) and has inward thereof a weakened region (5) formed through preferably both upper and lower walls, defining an opening strip (7). In preferred embodiments the upper and lower walls are semi-rigid plastic panels heat welded together along a periphery and perforated (6) adjacent the weld. To easily access the stored article, the user ruptures the weakened region, tears the opening strip away from the packaging unit to cause the upper and lower plastic material walls to separate. The pack can open like a clam-shell about a hinge (11) formed by second peripheral joint (9) and/or stepped portions (10) on a side opposite the tear strip.
