    Abstract: The present invention pertains to a UHMWPE film having a tensile strength of at least 2.0 GPa, a tensile energy to break of at least 30 J/g, an Mw of at least 500 000 gram/mole, and a Mw/Mn ratio of at most 8.
    The film may be manufactured via a process which comprises subjecting a starting UHMWPE with a weight average molecular weight of at least 500 000 gram/mole, an elastic modulus determined directly after melting at 160°C of at most 0.9 MPa, and a Mw/Mn ratio of at most 8 to a compacting step and a stretching step under such conditions that at no point during the processing of the polymer its temperature is raised to a value above its equilibrium melting point.
    The film may be used as starting material in any applications where high tensile strength and high energy to break are important. Suitable applications include ballistic applications, ropes, cables, nets, fabrics, and protective applications.
