The polymer coextrusion process is a new method of sheet metal lining. It allows to substitute lacquers for steel protection in food packaging industry. It consists in extruding different polymers in the same die in order to get a multi-layer product which will provide simultaneously adhesion properties (on metal) as well as mechanical and printing properties for the coating. The coextrusion process may exhibit flow instabilities at the interface between the two polymer layers. These instabilities depend on several parameters, e.g. processing temperatures and flow rates, differences in viscosity and elasticity. The objective of this study is to check the influence of processing and rheology parameters on the instabilities. Finite element nu...
