Temperature Isolation in Blown Film Dies, 2001 Polymers Laminations & Coatings Conference Proceedings

Damir Naden--Market demands that blown film processors produce multilayer film with the ability to thermoform and with improved properties such as barrier to moisture and oxygen. These properties require the use of materials with widely divergent melt temperatures. To coextrude materials of different melt temperatures, each individual material must be processed at its own ideal temperature. Temperature isolation in tested dies allows coextrusion of film consisting of materials with a melt temperature difference of up to 150 C. Based on trial results in Japan, USA and Canada this paper will demonstrate the ability to provide consistent temperature in each layer and super temperature isolation.
