PROBLEM TO BE SOLVED: To provide a multilayer film which can reduce the thickness in a packaging material and has excellent aroma retention property.SOLUTION: A multilayer film has at least a seal layer (A) and a resin layer (B). One surface layer is the seal layer (A). A film having aroma retention property can achieve thin thickness and suitable aroma retention property, in which the resin layer (B) contains a cyclic polyolefin resin, a thickness between the surface on the seal layer (A) side of the resin layer (B) and the surface of the seal layer (A) which becomes one surface layer of the multilayer film is 1-15 μm, the thickness of the seal layer (A) is 1-10 μm, and the total thickness is 50 μm or less.SELECTED DRAWING: None |
