/Panel, In Particular A Floor, Ceiling, Or Wall Panel; A Covering Constructed By A Multitude Of Such Panels; And A Method For The Recycling Of Such A Panel
Abstract

A panel of a planar design having a top side, a bottom side and multiple side edges, which panel has a laminated structure of layers that are adhered to each other. The layers include a core layer having a lower side and an upper side, and a top layer which is provided on the upper side of the core layer either directly or indirectly. At least two layers of the panel are directly or indirectly adhered to each other by an intermediate adhesive layer. The intermediate adhesive layer is composed of adjacent intermediate zones which include non-adhesive intermediate zones and adhesive intermediate zones, which intermediate adhesive layer establishes an adhesive strength between the two layers, such that a durable adhesion between the two layers is obtained, and a clean delamination of the two layers is allowed for when the two layers are subjected to a sufficient delamination force.
