how to deal with fog of disposable pet sushi box?

         The fog inside the sushi box is because the box is so airtight that the water generated by the sushi has no space to emit fog. The solution is to put holes in the lid of the packaging box to let the water vapor out.But in fact no need do that , because the disposable pet sushi box manufacturer always cover a anti fog coating on the PET lid .it looks clear and can increase the appetite.
