Vacuum-barrier packaging One day on March, at first, I went to on-site which cargoes were packed by local stuffs with manager, and I learned a lot of things there. I interested in ‘Vacuum-barrier packaging'. This is the way which transport precision instrument to protect from rust. I knew this way, but I have never seen the process. And I did not know that this packaging needs with desiccants in cargoes. Local stuffs did with practices hand, cargoes were quickly finished to pack up. I was very surprised at these sights. Moreover I have seen wooden boxes at Japanese warehouse, but I have never seen how to assemble the wooden boxes too. I went to on-site to see actual cargo and I thought it is important to see cargoes with my own eyes.
