Mehrschichtformkörper, Haftschicht(en) für denselben sowie Verwendung dieses Mehrschichtformkörpers
摘要
<p>The invention relates to adhesion/separating intermediate layers for recyclable multi-layer mouldings consisting of an inner and an outer layer and, if appropriate, middle layer(s), where the adhesion/separating intermediate layers consist of at least one starch moulding compound, are soluble in an aqueous medium and the layer materials of the multi-layer moulding can thereby be separated and recycled. The invention further relates to a process for dissolving adhesion/separating intermediate layers with a simultaneous separation of the individual layer materials of the multi-layer moulding so that these layer materials can be reused.</p>
