PSF PRE-STRETCH 250

Prestretch is the process that allows stretch film to be stretched before being applied to a load. Finished product thickness depends of raw material and could be only 5 µm - 6 µm, Still keep some power and tear resistance, enough for packaging. 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 and possibility to calculate film consumption per month, for example. 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 ton per month. It is the best choice for getting hand and machine pre stretch film rolls. 
Pre-stretch rewinder technology allows to use thin wall paper cores, which reduces cost of final products and transportation.
One more advantage of pre-stretched film rewinder is less garbage after using film, because the weight of pre stretched  film in several times less than standard film.
Our company offers high-performance, reliable machine with easy electronic tension adjustment and 2 stages pre stretch rewinder system, which allows to reach maximum possible speed for your material.
