Plastic container for dry solid food

摘要

A plastic container for a dry solid food, characterized in that it has a DLC (Diamond Like Carbon) film formed on the inner surface thereof, and has a steam permeability of 0 to 0.006 g/container/day and a steam permeability of 0 to 0.011 ml/container/day. The above gas permeability can be achieved by controlling the composition, density and film thickness of the DLC film. The plastic container can be suitably used for a dry and powdery food which has a smell, is susceptible to deterioration of quality by oxygen or is prone to agglomeration between fine particles by moisture and a dry and solid food which is markedly susceptible to deterioration of quality by moisture.
