Wood species can also affect the risk of mold. Species with more sapwood or more stored sugars are at a higher risk of fungal attack. Mold spores can usually be brushed from the wood surface, leaving little evidence of their presence; however, the fungus is still very much alive in the wood and can continue to grow and produce new spores if the wood remains wet.

The benefits are very high rigidity and low cost, but is difficult to mold, is very brittle, and cannot get wet. The cellulose expands and leeches the carbon black used to color the pallets. This type of plastic is often used in the production of one time use pallets or export pallets, this means that once they are sent out there will not be an expectation to have them returned.
