A film suitable for spiral packaging is highly sealable and provides a strong self-adhesiveness of the front and reverse sides of superposed films upon spiral packaging. The film includes two layers comprising (A) a layer including a resin composition containing at least one kind of adhesives-rendering resin having a resin density of 0.950 g/cm , such as rosin resins, at a concentration of 0.002 to 12.0% by weight in a polyolefin resin having a resin density of more than 0.910 g/cm , and (B) another layer including a resin composition containing the abovementioned adhesiveness-rendering resin at a concentration of 0.05 to 25.0% by weight and a plasticizing oil at a concentration of 0.01 to 8.0% by weight in a low density linear polyethylene resin having a resin density of 0.860 to 0.920 g/cm .
