摘要： The object of the present invention is to provide a layered film which exhibits, when used as a sealant film, excellent openability, good clouding property, high water vapor barrier property and superior seal strength stability and which is suitable as a medical packaging material, and to provide a packaging product thereof. The layered film comprises at least two layers of a resin composition layer [layer (A)] comprising (a) from 60 to 90% by mass of linear low-density polyethylene produced using a single site catalyst and (b) from 40 to 10% by mass of a polybutene-1, and a high-density polyethylene layer [layer (B)] comprising (c) a high-density polyethylene having a density of 0.950 to 0.970 (g/cm3). The packaging product has the layer (A) of the layered film as a sealant layer.
