PROBLEM TO BE SOLVED: To provide a stretch film comprising a resin containing no chlorine, having a packaging aptitude of a usual stretch film and capable of being used as a package for a frozen food. SOLUTION: The stretch film suitable for the package for the frozen food is obtained by making tanδof the film measured at a frequency of 10 Hz and at a temperature of -30 deg.C by a measurement of a dynamic viscoelasticity to 15 or higher. As such an example of the film, a film comprising a specific proportional ratio of mixed composition of two kinds of linear low density polyethylene based resins having a specific range of densities and a high pressure method polyethylene is included. The package aptitude at an ordinary temperature of this film is also good.
