PURPOSE: An improved one axial drawn film having a low gage is provided to have the improved intensity and durability by adding a pattern of sticking area or a network on a surface. CONSTITUTION: A cheap glue-reinforced film having large ventilation contains a film layer having a first surface and a pattern of sticking area added on the first surface of the film layer. The film layer is oriented in a drawing direction, has a valid gage under 0.6mil, and is produced from a mixture containing the 30wt.%-70wt.% polyolefin polymer, the 70wt.%-30wt.% filling agents and the 0wt.%-20wt.% second polyolefin polymer based on the whole weight of the film layer. The pattern of sticking area is added onto the surface of the film layer, and has the added amount about 0.1-20g/m2, the rate of connected area under 5wt.%-50wt.% for the surface unit area of the film layer, and the maximum interval between sticking areas in a horizontal direction to the drawing direction under 2.54cm.
