PURPOSE: An anti-dust film is provided to have excellent air permeation, moisture permeation and flexability, and to not generate scratch by comprising a polyethylene resin and a specific polyolefin-based elastomer. CONSTITUTION: An anti-dust film comprises 4-15 weight% of low density polyethylene, 30-45 weight% of medium density polyethylene, 4-8 weight% of high density polyethylene, 3-20 weight% of a polyolefin-based elastomer, and 40-55 weight% of inorganic filler. The anti-dust film additionally comprises 1-10 weight% of a surfactant master batch. The surfactant master batch comprises 20-40 weight% of surfactant and 60-80 weight% low density polyethylene. The polyolefin based elastomer has a melt index of 0.9-1.1 g/10min(190°C, 2.16 kg), and a density of 0.870-0.908 g/cm^3. |
