This research was performed to investigate the quality of leaflets provided with newspapers. The leaflets were classified according to business types and regions. The physical and strength properties were analyzed. The sizes of leaflets were 2, 4, 8 jeoljis of crown octavo, A3, A4, A5, and B3, B4, B5. Most of them were color printed and both-sides printing was much more popular than one-side printing. The leaflets about electronics, educations, and clothing showed lower density than restaurant business and other areas. The leaflets of electronics, educations, and clothing, and large stores showed lower tensile strength, and those of restaurant businesses and building trades showed relatively high tensile strengths. No differences on the quality of leaflets except for large stores were found according to business areas. Large markets made the leaflets with various types of papers, and low quality papers were also included.
