A flexible package of plastic with at least one wall, the wall comprising a polymer mixture of at least two components selected from: a) a polypropylene copolymer having a flexural modulus of elasticity of at most 800 MPa and a melt flow rate of at most 600 g/10 min (2.16 kg, 230° C.); b) a polypropylene other than that of component a) and having a melt flow rate of from 20 to 600 g/10 min (2.16 kg, 230° C.); and c) a polyolefin other than a polypropylene; wherein, if only component a) and component b) are present, component b) is a polypropylene copolymer; and wherein, if only component a) and component c) are present, component c) has a melt flow rate of at least 15 g/10 min (2.16 kg, 230° C.).
