Lightweight PalletsAlthough 85% of all unitized loads shipped in North America weigh less than 1, 000 pounds, most companies still use heavy wood pallets. Wood pallets are made to carry loads in excess of 2, 500 pounds, and can increase shipping costs, raise disposal fees, pile up in landfills and sometimes cause damage to the products theyre supposed to protect. Wooden pallets are even now prohibited by some countries and companies because wood-boring parasites love them.
