Abstract
There are provided a food container having improved oxygen barrier properties and a manufacturing method thereof. The food container includes a container made of a plastic material, a buffer thin layer formed on a surface of the container and having a thickness of 5 to 30 nm, and an oxygen barrier thin layer formed on the buffer thin layer. Accordingly, it is possible to provide a food container and a manufacturing method thereof, which can remarkably improve oxygen barrier properties by depositing, using a plasma method, an oxygen barrier thin layer on a porous plastic container having low surface energy without breaking the oxygen barrier thin layer.
