To obtain both a synthetic resin adhesive film providing sufficient self-adhesion, having excellent blocking properties, smoothly peelable when sent out, causing neither a release sound nor static electricity, having excellent adhesive power of films after drawing the film and winding a material to be wound with the film, excellent hygiene and recyclability and a pallet stretch film without using an expensive adhesive and surfactant.

This synthetic resin adhesive film comprises a copolymer of ethylene and a 3-18C α-olefin as a main component and has physical properties of (1) 0.1-20 g/10 minutes MFR, (2) 0.884-0.910 g/cm3 density and (3) one or more melt peaks obtained by differential scanning calorimetry(DSC) existing in the range of ≥68°C and <100°C but not in the range of ≥100°C.
