A printable, biaxially oriented polyolefin multilayer film which is low-temperature sealing on both sides and comprises a base layer and at least one sealing layer on each side of the base layer, the base layer containing a peroxide-degraded propylene homopolymer and each sealing layer containing an ethylene/propylene/butylene terpolymer and a propylene/butylene copolymer, one outer sealing layer containing a polydiorganosiloxane and silicon dioxide particles and not being corona-treated and the polydiorganosiloxane being added in the form of a masterbatch during the film production, results in a multilayer film especially useful as a packaging film.
