摘要

The present invention is a plastic container coated with a multi-layer barrier coating. The multi-layer barrier coating is useful for providing an effective barrier against gas permeability in containers and for extending shelf-life of containers, especially plastic evacuated blood collection devices. The coating has a first layer comprising an acrylate primer coating material, a second layer comprising a metal oxide and a third layer comprising an organic material.
