Touchette - Res 3 We have determined the tensile properties on films prepared from resin samples sent-from Mead Packaging. Plasticizers were added to the unmodified resins at the 10$ level, based on weight of final product. The 25 mil wet films were drawn down, giving a dry film of about 10 mils. Tensile properties were determined on the Instron using a 1" Sambone die, and a speed of 20"/min.
