Hi Vinit A good book that covers cast film extrusion is "Film Extrusion Manual- Process, Materials, Properties" it can be purchased on line from TAPPI- check out their book store at www.tappi.org Black Clawson produce cast film lines and you should be able to find some info there. http://www.blkclawson.com/content/8techtips/techset.htm The technical papers presented at SPE's ANTECs will have some useful info too. In general, end product properties such as tensile and impact strenght depend on the morphology induced in the raw material by the process used to convert it. Semi-crystalline materials such as PP are quite sensitive to variations process heat transfer conditions. Steve H Web searches on the materials (and their makers) should uncover some useful info IP: Logged |
