(57) [Summary] [Structure] The composition distribution variation coefficient (Cx) shown in the following formula 1 is 0.40 or less, and the ethylene content is 50 mol%. A packaging film, which is formed by laminating at least one other layer on the layer formed of the above ethylene-α-olefin copolymer (A). ## EQU1 ## Cx = σ / SCB ave σ: standard deviation of composition distribution (1/1000 C) SCB ave : average value of short chain branches per 1000 C (1 / 1000C) [Effect] A multi-layered packaging film having excellent safety and hygiene properties, low odor, transparency, mechanical strength, flexibility and low-temperature sealability and excellent in automatic packaging suitability is provided. |
