(57) [Summary] [Purpose] Good transparency and low-temperature heat sealability, suitable for high-speed automatic packaging, even after long-term high-speed automatic packaging. Provided is a biaxially stretched film in which added fine particles do not fall off to contaminate a packaging machine. [Structure] The following components A and B are provided on at least one surface of a crystalline propylene-based polymer or a base material layer containing this as a main component. A biaxially stretched multi-layer film, which is obtained by laminating layers of a composition comprising: and a component C. Component A: Propylene random copolymer 100 parts by weight Component B: Inorganic or organic fine particles having an average particle size of 0.5 to 5 μm 0.05 to 0.6 parts by weight Component C: Number average molecular weight 800 to 20, 000 acid-modified polypropylene 0.5 to 10 parts by weight |
