Plastic Bin Boxes of molded polypropylene plastic are virtually indestructible. Reinforced edges give additional strength. Bin boxes are water-proof and unaffected by grease and oil. A hanglock molded into the back of each bin secures it to the shelf above and prevents contents from spilling out when bin is fully extended.

Except Plastic Bin Boxes there are also Corrugated Bin Boxes, but they are not strong and destructive, that’s why plastic bin boxes are much more better.
