A system for coinjection molding a multi-layer container includes an injection molding apparatus, a camera, and a controller. The injection molding apparatus is configured to coinject a plurality of polymeric materials into a mold cavity to form a multi-layer container including an inner layer, an outer layer, and a barrier layer located between the inner layer and the outer layer. The camera is configured to capture an image indicating a location of the barrier layer within the multi-layer container. The controller is configured to monitor the location of the barrier layer using the image captured by the camera, compare the location of the barrier layer to a threshold location, and provide a control signal to the injection molding apparatus based on the location of the barrier layer relative to the threshold location.
