Packaging material for yam transport storage using it with yam transport storage containers

摘要

[Problems] to consumption areas from origin and while maintaining a natural look immediately without also harvest that causes reduction of the yam, transported, and also makes it possible to store long days. The A yam 20 in a non-permeability of the container body 2 it will be placed in a plurality of stages. In doing so, while the container body 2 and the yam 20, during the yam 20 of each stage, between the yam 20 and the lid 3, placing an open cell flexible polyurethane foam sheet 12. Preferably, the open-celled flexible polyurethane foam sheet 12 between the between the container body 2 and the yam 20 and the yam 20 and the lid 3 is a two-layer structure, it keeps hydrolysis the required amount of water on the outside of the sheet. Instead of the two-layer structure, using an open cell flexible polyurethane foam sheet 10 with profile machining may be performed there hydrolysis process. .BACKGROUND
