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 30nm, 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.

Description

technical field [0001] One aspect of the present invention relates to a food container and a manufacturing method thereof, and more particularly, to a method that can deposit an oxygen barrier thin layer on a porous plastic container with low surface energy by using a plasma method without destroying the oxygen barrier thin layer. Layer to significantly improve the oxygen barrier properties of the food container and its manufacturing method. Background technique [0002] In order to preserve perishable foods for a long period of time, it is very important to provide food containers with oxygen barrier properties. [0003] Plastic food containers have the advantages of low production cost and easy mass production, but have the disadvantage that oxygen barrier properties are significantly reduced by the porous structure, a unique feature of plastics. [0004] In order to solve such disadvantages, research into a technique of coating thin layers on plastic food containers usin...
