PROBLEM TO BE SOLVED: To provide a stretch film for packaging excellent in characteristics such as transparency, packaging workability, package quality, elastic recovery and bottom seal properties, stability of a film with time and cost effectiveness. SOLUTION: This stretch film for packaging is composed of at least three layers, in which both of the surface layers are comprised of an ethylenic polymer (A) and at least one of the intermediate layers is comprised of a resin composition including 55-96 wt.% of a polypropylene polymer (B), 3-25 wt.% of petroleum resins (C) and 1-20 wt.% of a liquid additive (D). This provides a stretch film for packaging excellent in transparency, elongation properties, deformation recovery, packaging machinability, workability and the like, and having no problem in waste disposal and food sanitation.
