A ball can comprising a can base and a can wall, wherein the can wall at least in one or more sections comprises a roughened surface and wherein, for marking the can, a layer of another material is applied to the can wall such that the surface roughened at least in one or more sections is at least partially exposed;
- wherein the layer of another material has another density than the density of the ball can material, wherein a difference in density is at least 0.02 g/cm3;
- wherein the ball can comprises polyethylene terephthalate;
- wherein a roughness of the can wall is characterized by one or more of the following parameters:
- Ra at least 0.5 μm, Ra at least 1.0 μm, Ra at least 1.5 μm, Ra at least 2.0 μm, Rz at least 2.0 μm, Rz at least 4.0 μm, Rz at least 6.0 μm, Rz at least 8.0 μm, Rz at least 10.0 μm.
A ball can comprising a can base and a can wall, wherein the can wall comprises a roughened surface and wherein, for marking the can, a layer of another material is applied to the can wall such that the roughened surface is at least partially exposed;
- wherein the can wall comprises an outer circumference and wherein the layer of another material extends around at least 50% of the outer circumference;
- wherein the layer of another material has another density than the density of the ball can material, wherein a difference in density is at least 0.02 g/cm3;
- wherein the ball can comprises polyethylene terephthalate;
- wherein a roughness of the can wall is characterized by one or more of the following parameters:
- Ra at least 0.5 μm, Ra at least 1.0 μm, Ra at least 1.5 μm, Ra at least 2.0 μm, Rz at least 2.0 μm, Rz at least 4.0 μm, Rz at least 6.0 μm, Rz at least 8.0 μm, Rz at least 10.0 μm.
A ball can comprising a can base and a can wall, wherein the can wall comprises a roughened surface and wherein, for marking the can, a layer of another material is applied to the can wall such that the roughened surface is at least partially exposed;
- wherein the roughened surface of the can wall is sufficiently transparent that it can be seen with a naked eye whether there is a ball in the ball can;
- wherein the layer of another material has another density than the density of the ball can material, wherein a difference in density is at least 0.02 g/cm3;
- wherein the ball can comprises polyethylene terephthalate;
- wherein a roughness of the can wall is characterized by one or more of the following parameters:
- Ra at least 0.5 μm, Ra at least 1.0 μm, Ra at least 1.5 μm, Ra at least 2.0 μm, Rz at least 2.0 μm, Rz at least 4.0 μm, Rz at least 6.0 μm, Rz at least 8.0 μm, Rz at least 10.0 μm.
