PROBLEM TO BE SOLVED: To obtain a film for stretch-wrap package having suitable transparency, stretchability and automatic packaging suitability as a high magnification stretched packaging film. SOLUTION: The stretch-wrap packaging film comprises a 3-layer structure having a base material layer and both surface layers. In this case, the material layer contains 100 pts.wt. of polypropylene resin having 40 to 80 wt.% of noncrystal component measured by a pulse method NMR and 0.1 to 10 g/10 min of MFR, and 1 to 15 pts.wt. of surfactant such as glycerol fatty acid ester or polyglycerol fatty acid ester. And, the surface layer is formed of ethylene- vinyl acetate copolymer containing 10 to 28 wt.% of vinyl acetate content. |
