High-speed baling and wrapping operations depend on achieving greater coverage from each roll without sacrificing bale protection. For Australian custom harvesting contractors, bale wrap performance is closely linked to pre-stretch settings, film gauge, wrapper speed and the condition of the bales being wrapped. Running film at roughly 55% to 70% pre-stretch can improve yield, but only when the wrapper, film and crop conditions are correctly matched. Excessive stretching can cause tear-outs, weak overlaps and uneven coverage. The goal is not simply to stretch the film as far as possible, but to achieve consistent tension and reliable sealing throughout long wrapping runs. Understanding Pre-Stretch and Film Yield Pre-stretch is the controlled…
