Pre-stretch is the process that allows stretch film to be stretched before being applied to a load. It is only 5 µm - 8 µm thick, it is very strong and tear resistant. In case of the pre-stretch, less film is required to wrap a pallet than in case of any standard products. As much lower quantities of the product are used to wrap the load, this provides for substantial financial savings. The main advantage of the machine is pre-stretch effect while winding. According to technical tasks film tension may reach 400%. The machine enables stable work and average output of 50 tons pre-stretch film per month. It is the best choice for getting hand and machine pre-stretch film rolls.
