• Protective. Another thing cardboard doesn’t do is seal off and protect the contents of your container. Plastic on the other hand does, if you buy a sealable container. Plastic bins with lids can keep out moisture and protect your possessions from the elements. This makes them perfect for self storage, or an attic or basement which may be susceptible to humidity and mold.

• Transparent. You have the option of buying clear plastic bins, which unlike wood, cardboard, or metal, are see-through. You can figure out what’s inside instantly without having to open and close your bins. You may find it easier to see at a glance than labeling, and you don’t have to worry about labeling every side of your boxes this way.
