Container with globe-like particles and an inner metal layer and method for its fabrication

A method for producing a container made of a plastic composition having an inner coating on an inner surface of the container, the inner coating having a maximum thickness of 1000 nm and comprising at least one metal layer,

• the 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.
