摘要

A coextrusion apparatus, a single-layer extrusion apparatus, a retrofit kit, as well as to a method for measuring a layer thickness, for producing a plastic film, and for retrofitting an extrusion apparatus. From the state of the art, it is known to add a detection agent in the form of a fluorescent granulate into the starting material at the extruder, in order to be able to measure the layer thickness of the layer in the film composite produced from this starting material. However, it is proposed to feed in a detection agent only beyond the extruder. This leads to a clearly shorter running time of the detection agent through the system and thereby to clearly faster measurability of changes in the production parameters.
