There are provided a food container having a silicon incorporated diamond like carbon (Si-DLC) layer and a method thereof. The food container includes a container made of a plastic material; an intermediate thin layer formed on a surface of the container; and a Si-DLC layer formed on the intermediate thin layer. Accordingly, it is possible to provide porous plastic container having a Si-DLC layer and a manufacturing method thereof, which can implement high oxygen barrier properties and excellent mechanical characteristics by stably depositing a Si-DLC layer on a food container having lower surface energy without breaking the Si-DLC layer.
