Abstract

Coextrusion is an important method for making barrier and optical products at large scale. In these multilayer polymer films, adhesion is critical for performance, yet is difficult to predict by small scale experiments. Past work has shown vast differences between bilayers produced in coextrusion (continuous process) versus lamination (batch, quiescent process). In this work, a small scale coextruder die is designed and attached to a dual-bore capillary rheometer. Model films are quickly produced for adhesion testing, with adhesion showing a strong dependence on residence time.
