Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a multilayered self-adhesive film suitable for a palette stretch film having self-adhesive properties, not generating peel noise or static electricity at the time of delivery and a lowering of self-adhesive strength at a time of stretching, high in rigidity and excellent in restraint force after stretching and tear resistance. SOLUTION: A self-adhesive film (for a surface layer) comprising an ethylene/α-olefin (3-18C) copolymer and characterized by that 180 deg. peel self-adhesive strength at a time of non-stretching is 3-35 g, average surface roughness at a time of non-stretching measured by an interatomic microscope is 6.5 nm or less and average surface roughness at a time of stretching is 5.5 nm or less and a polyethylene resin film comprising an ethylene/α-olefin (6 or more C) copolymer with an MFR of 0.1-10 g/10 min and a density of 0.900-0.945 g/cm3 are laminated to form a multilayered self-adhesive film used as a palette stretch film.
