Zusammenfassung:Provided is a multi-layer non-oriented polyolefin film having a high fusion-sealing strength and minimal variation therein, outstanding optical properties such as haze, luster and image sharpness, and exhibiting an excellent anti-static effect, even with a minimal quantity of anti-static agent contained. This multilayer non-oriented polyolefin film comprises a layer A which is the outermost layer, a layer B which is an intermediate layer, and a layer C which is the outermost layer, laminated in that order, and characterized in that layer A and layer C are respectively formed from a polypropylene resin containing a propylene-ethylene random copolymer obtained by polymerization using a metallocene catalyst; layer B is formed from a polyolefin resin containing long-chain branched LLDPE, LLDPE, polypropylene resin and an anti-static agent, and that the film is used in fusion-sealing applications. 本发明提供种聚烯烃系未拉伸多层膜,该多层膜的熔断密封强度高,同时该熔断密封强度的不均匀性小;雾度、光泽度、图像清晰度等光学特性优异;即使在抗静电剂的配合量为少量的情况下,也能显现出优异的抗静电效果。所述多层膜是由作为最外层的A层、作为中
