PROBLEM TO BE SOLVED: To provide a novel non-chlorine-based stretch wrapping film which exhibits favorable wrapping aptness such as favorable wrapping efficiency and a beautiful wrapping finish even if wrapping is performed by an automatic wrapping machine adapted for polyvinyl chloride.SOLUTION: The stretch wrapping film is a laminate film comprising at least three layers including: outermost layers essentially comprising an ethylene-based resin (A) component; and a middle layer essentially comprising a propylene-based resin (B) component. According to a dynamic viscoelasticity measurement method, the film shows an average loss tangent (tanδ) of 0.12 or more in a temperature range from -40 to 0°C and a loss tangent (tanδ) of 0.20 or more at 20°C at a vibration frequency of 10 Hz and a strain of 0.1%. |
