摘要

PROBLEM TO BE SOLVED: To provide a film which is excellent in sawtooth cutting properties and can be used as a self-adhesive packaging film and a self-adhesive packaging film having better sawtooth cutting properties. SOLUTION: The multi-layer film is composed at least of a layer (X) and a layer (Y). The layer (X) comprises a resin composition containing 20-100 wt.% a propylene resin (a) at least 1.8 in die swelling ratio and 80-0 wt.% of an olefin resin (b) different from the propylene resin (a), and the layer (Y) comprises a thermoplastic resin different from the resin composition of the layer (X). The self-adhesive packaging film is obtained from the multi-layer film.
