Packing peanuts are a void-fill packaging product made typically of expanded polystyrene.  Consisting of over 99.6% air, they consist of small pieces of sturdy protective packaging that is used to fill in the empty space between merchandise and exterior cartons to ensure that what you’re shipping (or receiving) will not rattle or suffer damage in transit.  Easy, durable, and effective!  JustShippingSuplies now offers you biodegradable packing peanuts from Staples.  Economical and environmentally friendly, these peanuts are static-free and made from corn starch, allowing them to easily dissolve in water.  Safety is a top concern when shipping merchandise or belongings, and nothing is easier that packing peanuts; just pour the peanuts into the unoccupied space(s) in the box to be shipped, seal the box, and ship.
