The present invention is a container assembly that includes an inner tube formed from a plastic that is substantially inert to bodily fluids and an outer tube that is formed from a different plastic. Collectively, the container assembly is useful for providing an effective barrier against gas and water permeability in the assembly and for extending the shelf-life of the container assembly, especially when used for blood collection. The outer surface of the inner tube and/or the inner surface of the outer tube are provided with a matte finish that forms an array of peaks and valleys. The valleys form circuitous paths that accommodate a flow of air to facilitate insertion of the inner tube into the outer tube. The circuitous paths also allow air to vent during processing to low pressure.
