Abstract: PURPOSE: A biaxially oriented polyester laminating film is provided to have excellent drawing property and to satisfy low gloss and high roughness by producing a laminated three-structured film. CONSTITUTION: 5.0 to 115 micrometer particles are selected to adjust gloss inside a biaxially oriented polyester film and to adjust roughness of the film surface into a more regular roughness. A layer containing the particles becomes both surface layers(A,C) and a middle layer(B) is structured with polyester containing 1.0 to 3.0wt% of the 0.01 to 7.0 micrometer particles. The gross is from 0% and more than 0% to 45% and less than 45%. The average roughness is from 400nm and more than 400nm to 2000nm and less than 2000nm. Therefore, the biaxially oriented polyester film having excellent drawing property and prevented from tearing on a horizontal drawing process is produced by limiting the particles in the middle layer.
