Panel, in particular floor panel, ceiling panel or wall panel, covering composed of a plurality of panels, and method of recycling panels
By introducing an intermediate adhesive layer and a non-adhesive area into the panel, the bonding strength is reduced, which solves the problem of incomplete layer separation during panel recycling and improves recycling efficiency and material purity.

AI Technical Summary
Technical Problem
In the recycling process, existing panels are difficult to completely separate due to the high bonding strength of the adhesive, resulting in incomplete separation of each layer, which leads to pollution of the basic material processing stream and low recycling efficiency.
Method used
The intermediate adhesive layer consists of adjacent adhesive and non-adhesive areas, which reduces the adhesive strength and allows the panel to be completely peeled off with appropriate peeling force after use, making it suitable for recycling.
Benefits of technology
This achieves complete separation of each layer of the panel, improving the purity and recycling efficiency of the basic material stream during the recycling process.

Abstract
A panel (1), in particular a floor panel, a ceiling panel or a wall panel, having a planar design, the panel (1) having a top side (7), a bottom side and a plurality of side edges (3a-3d); the panel having a laminate structure of a plurality of layers (28, 30, 32) adhered to each other, wherein the plurality of layers extend parallel to the plane of the panel and comprise: a core layer (28) having a lower side and an upper side; and a top layer (30) disposed directly or indirectly on the upper side of the core layer; wherein at least two layers of the panel, in particular the top layer and the core layer, are adhered to each other directly or indirectly by means of an intermediate adhesive layer (27); wherein the intermediate adhesive layer consists of adjacent intermediate regions comprising non-adhesive intermediate regions and adhesive intermediate regions; wherein the intermediate adhesive layer establishes an adhesive strength between two layers such that a durable adhesion is obtained between the two layers and allows a complete peeling of the two layers when the two layers are subjected to a sufficient peeling force.
