Abstract:
1. Process for the production of a labelled container by means of the blow-moulding process, in which a thermoplastic polymer is extruded as melt tube through an annular die into a two-part mould, in which a film or at least one film section has been laid, and the melt tube is squeezed at one end by closing the two-part mould and air is introduced at the opposite end in such a way that the melt tube is inflated and adapts itself to the mould in such a way that a hollow body is shaped, and at the same time the laid-in label is applied, characterized in that the label consists of a biaxially oriented porous film which has an open-pored network-like structure produced during production of the film by conversion of β-crystalline polypropylene into alpha-crystalline polypropylene during the stretching.
