Recyclable label foil

Recyclable label foil (3) for in-mold labeling of synthetic containers to be produced by extrusion blow molding, with at least three co-extruded layers, where at least one core layer is located between two top layers and where at least one of the top layers consists of a sealable synthetic material that softens at or below the temperature of the blow mold, characterized in that

• the top coatings (3.1, 3.3) are made of polyethylene and the core layer (3.2) of polypropylene, and
• the two top layers (3.1, 3.3) each have about the same thickness and in that the core layer (3.2) has about 5 times to 20 times the respective thickness of one top layer (3.1, 3.3).

Recyclable label foil (3) as set forth in one of the aforementioned claims, characterized in that at least the core layer (3.2) is filled with mineral filler materials such as chalk, lime, titanium oxide or talc with a fill content of 5 to 40 percent in weight.

Recyclable label foil (3) as set forth in one of the aforementioned claims, characterized in that the filler material is talc with an average particle size of 2 to 20 μm, preferably with a particle size of 2 to 5 μm.

Recyclable label foil (3) as set forth in one of the aforementioned claims, characterized in that the label foil (3) is a five-layer co-extruded product, where a coextruded adhesion-supporting layer (7.1, 7.2) with a thickness of 5 to 8 μm is located between each of the top layers (3.1, 3.3) and the core layer (3.2).
