A prestretched polyethylene film is provided having a longitudinal degree of prestretching in the range of from 100 % to 400 % and a remaining longitudinal elongation capability in the range of from 100 % to less than 300 % as determined according to ASTM D882. The film comprises at least 25% by weight of a linear low density polyethylene (LLDPE) substantially free from long chain branching (LCB) and having a density below 915 kg/m3. The film is particularly useful as a net replacement film in the baling of compressed bulk material, such as silage, and may offer to users improved flexibility and reliability and/or increased yield.
