Flexible software for modeling polymeric film production by use of blown extrusion has been developed. It consists of library of mathematical models for extrusion and forming blown film, sub-system for changeover to new type of film and sub-system for investigation of extrusion and forming for film quality control under film production. The sub-system for changeover allows to choose the equipment of extrusion line on technical and economic indices, to synthesize 3D model of the line and to generate regulation ranges of regime parameters for given type of film. The sub-system for investigation allows to calculate temperature profiles of heating and cooling material, geometrical and optical characteristics of film depending on regime parameters for stages of extrusion and forming and to evaluate regime parameters ensuring given quality of polymeric film.
