Our film is made from the finest FDA polyethylene resin you can find. We strive for lot to lot consistency in our resins and our blends. As a matter of fact we have one particular resin we have been purchasing for more than 15 years and a second for nearly ten years.  Our blends are metered by gravimetric controls so each batch is weighed and adjusted before it goes into to the extruder.  Consistency in resins and consistency in blends.
