Claim 17:
18. The container according to claim 11, wherein the container is obtainable by a method comprising:
preparing the plastic composition comprising at least one base polymer material and at least a first additive, wherein at least 2.5% by volume of a total volume of the plastic composition is made up by the first additive and wherein the first additive comprises globe-like shaped particles having a hardness on the Mohs scale of at least 4;
extrusion blow molding of the container by
a) heating and blending the prepared plastic composition until at least the base polymer material is plasticized;
b) forming a parison by a die and a blow pin, wherein the globe-like shaped particles of the first additive are accumulated on an inner surface of the parison resulting from shear forces exercised by die and blow pin;
c) blow molding of the parison to form the container, wherein globe-like shaped particles of the first additive which located on the inner surface of the container increase the surface area and the hardness of the inner surface of the container;

applying the at least one metal layer of the inner coating onto the inner surface of the container, wherein the applied metal layer bonds to the globe-like shaped particles of the first additive located on the inner surface of the container.
