PURPOSE:To facilitate the cutting in a lateral direction by setting the shrinkage factor of a film in the flow direction thereof to 5-25% at 60 deg.C and setting the Elmendorf tear strength of the film in the direction right-angled to the flow direction to 2-30gf at 20 deg.C. CONSTITUTION:The shrinkage factor in the flow direction of a packing stretch- wrap film composed of a soft vinyl chloride resin is set to 5-25% at 60 deg.C and the Elmendorf tear strength of the film in the direction right-angled to the flow direction is set to 2-30gf at 20 deg.C. An article is wrapped in this packing stretch-warp film to obtain a stretch-wrap package made easy to tear in one direction.
